Image Resizer

No, absolutely nothing gets uploaded anywhere—this tool operates entirely within your web browser using JavaScript and the pdf-lib library for client-side PDF processing. When you select a PDF file, your browser reads it directly from your local storage, processes all page removal operations in browser memory, and generates the modified PDF locally before offering it for download. The file never leaves your computer at any point in the workflow. You can verify this privacy guarantee yourself: open your browser's developer tools (press F12 in Chrome, Firefox, or Edge), switch to the Network tab, select and process your PDF, and observe that zero network requests are made to any server during the entire operation—the network activity will be completely silent except for the initial page load. This architecture provides absolute privacy for sensitive documents: confidential business contracts, legal filings with privileged information, medical records with protected health information, financial documents with personal data, or any private materials can be processed without any risk of server exposure. Unlike server-based PDF tools where you must trust the provider's claims about deleting files after processing (with no way to independently verify), our browser-based approach makes server uploads technically impossible—the code simply does not include any server communication functionality. For organizations with strict data security policies (legal firms with attorney-client privilege requirements, healthcare providers with HIPAA compliance obligations, financial institutions with regulatory data protection mandates), this verifiable client-side processing provides the compliance assurance that IT and legal teams require before approving tool usage. The trade-off is that browser-based processing has file size limits (50MB) and may be slower for very large documents compared to server-based tools with dedicated processing hardware, but for most users the absolute privacy guarantee outweighs these minor limitations.

The two modes provide opposite approaches to page selection, and choosing the right one dramatically affects efficiency. Remove mode (the default) deletes all pages you select and keeps everything else—this is ideal when you want to eliminate a few unwanted pages from a larger document. For example, removing 5 blank pages from a 50-page scanned contract, deleting 3 pages of sensitive information from a 30-page report, or eliminating a 2-page appendix from a proposal. With Remove mode, you select the pages you do not want and the tool discards them. Keep mode does the opposite: it keeps only the pages you select and removes everything else—this is perfect when you want to extract a few specific pages from a large document. For example, extracting pages 15-20 (6 pages) from a 200-page manual, pulling out pages 45, 67-72, and 88 (9 pages total) from a 150-page research paper, or grabbing just the title slide and conclusion slides (pages 1 and 78-80) from an 80-slide presentation. With Keep mode, you select the pages you want and everything else gets discarded. The efficiency difference is substantial: imagine a 100-page document where you only want pages 5-8. In Remove mode, you would need to select 96 pages (1-4, 9-100)—extremely tedious. In Keep mode, you just select 4 pages (5-8) and you are done. Conversely, if you want to remove just pages 5-8 from that same 100-page document, Remove mode requires selecting only 4 pages while Keep mode would require selecting 96 pages. The general rule: if you are keeping more pages than removing, use Remove mode; if you are removing more pages than keeping, use Keep mode. The tool makes switching between modes easy—just select your pages once, then choose the appropriate mode button based on your intention. For complex scenarios, sometimes it helps to count: "I have a 75-page document and want pages 10-15, 30-35, and 50-65 (total 27 pages). That means I am keeping 27 and removing 48, so Keep mode is more efficient." The visual page counter helps with this decision—it shows "X pages selected" in real-time, letting you compare selection count to total page count to determine which mode requires less work.

Yes, the range input field supports sophisticated selection syntax that lets you specify complex page patterns in a single expression, dramatically faster than clicking individual pages. The syntax accepts: individual page numbers separated by commas (5,8,12,20), page ranges using hyphens (1-10 means pages 1 through 10 inclusive), and any combination of both (1-5,8,12-15,20,25-30). This makes it easy to select complicated patterns: "1-3,5,7-9" selects pages 1, 2, 3, 5, 7, 8, and 9 (useful for removing scattered blank pages), "10-20,35-45,67" selects pages 10-20, 35-45, and page 67 (perfect for extracting multiple chapters), or "1,5,10,15,20,25" selects every fifth page (maybe you want only section divider pages). The syntax is forgiving: spaces are ignored, so "1-5, 8, 12-15" works identically to "1-5,8,12-15". Page numbers are validated against your document—if you enter "1-100" but your PDF only has 75 pages, the tool selects 1-75 and ignores the invalid numbers. After entering your range expression and pressing Enter or clicking apply, the visual page grid updates immediately to highlight all selected pages, giving you instant visual confirmation that your selection is correct before processing. This range syntax is particularly powerful for documents with patterns: removing all even-numbered pages (2,4,6,8,10...), extracting alternating sections, or selecting regular intervals. For very large documents, the range syntax can save minutes compared to manual clicking: selecting pages 1-50 and 100-150 from a 200-page document means typing "1-50,100-150" (about 2 seconds) versus clicking 100 individual page buttons (probably 60+ seconds even clicking quickly). The feature also helps avoid errors: when manually clicking 50+ pages, it is easy to accidentally miss one or select the wrong page; the range syntax ensures exact precision. Pro tip: if you want to select most pages with just a few exceptions, sometimes it is faster to use "Select All" and then click to deselect the few pages you do not want, rather than using range syntax to specify many ranges. The tool gives you multiple approaches—visual clicking, range syntax, and bulk operations—so you can choose whatever feels fastest for your specific selection pattern.

Your original PDF file is never modified—the tool creates a completely new PDF file with your changes while leaving your original untouched and intact on your device. This "non-destructive editing" approach is critical for safety and workflow flexibility. Here is what happens technically: when you select a PDF, your browser reads the file into memory and displays it in the tool interface, but the file itself remains exactly as it was on your storage. When you process page removal or extraction, the tool uses the pdf-lib JavaScript library to construct an entirely new PDF document by copying only the desired pages from the original (in their original quality and format), then offers this new PDF for download with a modified filename (typically "removed-pages-[original-name].pdf" or "kept-pages-[original-name].pdf" to distinguish it from the original). Your original file stays in its original location with its original name, completely unchanged. This safety-first design means you can experiment fearlessly: if you accidentally remove the wrong pages, simply reload the original file and try again—you have not lost anything. For workflows requiring multiple versions of a document (creating different customized versions for different audiences), you can process the same original PDF multiple times with different page selections, generating as many customized versions as needed while always having the pristine original to return to. This also protects against browser crashes or errors: if something goes wrong during processing, your original file is safe because it was never being edited directly. The non-destructive approach contrasts with desktop PDF editors like Adobe Acrobat where "delete pages" typically modifies the open document directly (requiring you to remember to "Save As" rather than "Save" if you want to preserve the original). Our tool eliminates that risk by making it impossible to overwrite your original—you always get a new file, always keep your original. For archival or legal workflows where document preservation is critical, this guarantee provides essential peace of mind. The only consideration is storage: you will end up with both the original and processed versions, consuming more disk space than if you replaced the original, but most users find this trade-off worthwhile for the safety and flexibility it provides.

The file size limit is 50MB, which accommodates most typical business documents, reports, manuals, and even lengthy publications—though the actual page count this represents varies enormously depending on content type. A text-heavy document with minimal graphics might have 1,000+ pages within 50MB, while a photo album or design portfolio with high-resolution images might reach 50MB with only 50-100 pages. There is no hard page count limit—if your file is under 50MB, the tool will process it regardless of whether that is 50 pages or 500 pages. However, practical performance considerations apply for very large documents: files approaching the 50MB limit or containing hundreds of pages may take longer to process (potentially 10-30 seconds instead of 1-3 seconds for typical documents), require more browser memory (which could cause slowness if your computer has limited RAM or many other applications running), and may strain older devices or mobile browsers that have less computational power. The visual page grid displays all pages as thumbnails, which works well up to a few hundred pages but becomes unwieldy for extremely long documents (scrolling through 1,000 page thumbnails would be tedious, though the range input syntax provides an alternative to clicking). For optimal performance, the tool works best with documents under 200-300 pages or 30MB, though it can handle larger files if your device has adequate resources. If you encounter slowness or browser unresponsiveness with a very large file, try these approaches: close other browser tabs and applications to free memory, use a desktop computer rather than a mobile device if available, or split your large PDF into sections using a PDF splitter tool, process each section separately, then merge the results back together if needed. The 50MB limit exists primarily to prevent browser crashes that would waste your time—attempting to process a 200MB file could exhaust browser memory and crash the tab, losing your selection work. If your document exceeds 50MB, you have several options: use desktop PDF software like Adobe Acrobat (which has no file size limits but requires purchase and installation), compress the PDF first to reduce file size (our PDF Compressor tool or others), or split the document into smaller sections and process them individually. For most users, though, the 50MB limit is not restrictive—typical business documents, contracts, reports, presentations, and even substantial manuals generally fall well under this threshold. A useful benchmark: 50MB can accommodate roughly 5,000 pages of plain text, 500 pages of typical business documents with some graphics, or 100 pages of high-resolution photo-heavy content, so unless you are working with extremely large publications or image-intensive materials, you will likely never hit the limit.

Yes, the tool preserves all document features perfectly because it copies pages at the PDF object level rather than rendering and recreating them. When you process a PDF, the pdf-lib library (which powers this tool) operates on the actual PDF data structures—it extracts complete page objects with all their associated resources (text, images, fonts, annotations, metadata) and includes them in the new PDF exactly as they existed in the original. This means: all text remains searchable and selectable with identical fonts and formatting, all images maintain their original resolution and quality (no recompression or quality loss), all hyperlinks (both external URLs and internal document links) work exactly as before, any form fields remain functional with their original properties, bookmarks and table of contents entries are preserved, page layouts and dimensions stay identical, and document security settings (except passwords, which are removed during processing) are maintained. You can verify this yourself: process a PDF with complex formatting, hyperlinks, or embedded media, then compare the original and processed versions—they will be visually and functionally identical except for the removed pages. The quality preservation is "lossless"—you are not losing fidelity or introducing compression artifacts the way you would if the tool were rendering pages to images and recreating the PDF. This is crucial for documents where precision matters: legal contracts where every word must be exact, technical manuals where hyperlinked cross-references must work, academic papers where citations and formatting must be preserved, or any professional document where quality degradation would be unacceptable. One caveat about internal page references: if your PDF has hyperlinks that point to specific page numbers (like "see page 45"), and you remove pages before page 45, those page numbers will no longer be accurate because the page numbering changes when pages are removed. The links themselves still work (they point to whatever is now at that position), but if the document has text saying "page 45" that text will not automatically update to reflect the new page number. This is a limitation of PDF structure, not our tool—even professional PDF editors cannot automatically renumber textual page references. For most documents this is not an issue because page references are uncommon, but it is worth knowing if you are working with heavily cross-referenced technical documents. Similarly, table of contents entries that list page numbers may become inaccurate after page removal. If this matters for your document, you may need to regenerate the table of contents after processing (which typically requires the source document application, like Microsoft Word, rather than PDF tools). For most use cases—removing blank pages, deleting sensitive sections, extracting chapters—these edge cases are irrelevant and the tool provides perfect quality preservation.

No, the tool cannot process password-protected or encrypted PDFs—if you attempt to upload a secured document, you will receive an error indicating the file is encrypted and cannot be processed. This limitation exists because PDF encryption prevents unauthorized access to the document structure, and page removal requires reading and manipulating that structure. When a PDF is password-protected (either with a user password that prevents opening, or an owner password that restricts editing/printing/copying), the file's content is encrypted using cryptographic algorithms. Without the correct password to decrypt the file, software cannot access the page objects needed for removal—the internal data is essentially scrambled. Even if we added password input functionality allowing you to unlock the PDF for processing, browser-based JavaScript PDF libraries have limited support for the various encryption standards used by different PDF creation tools, which could result in corruption or compatibility issues. If you need to remove pages from a password-protected PDF, follow this workflow: use desktop PDF software (Adobe Acrobat, Preview on Mac, or other tools) to open the encrypted PDF with the password, then "Save As" or "Export" an unencrypted version (most PDF tools offer a "Remove Security" or similar option when saving, provided you have the password to open the file). Once you have an unencrypted version, you can process it with our tool. If you need the final document secured, use desktop software to re-apply password protection after page removal. This three-step process (decrypt, remove pages, re-encrypt) maintains security while enabling page manipulation. The inability to handle encrypted PDFs is actually a security feature: if our tool could bypass PDF password protection, it would represent a security vulnerability. The fact that secured PDFs cannot be processed confirms that PDF encryption is working as designed to prevent unauthorized manipulation. For most users, this is not a significant limitation—the majority of PDFs are not password-protected, and when they are, you typically have the password (since you created or received the file) and can remove encryption temporarily for processing. For organizational workflows with many encrypted PDFs, consider processing documents before applying encryption as the final step, or maintain both encrypted and unencrypted versions (encrypted for distribution, unencrypted for internal editing). The tool does preserve most document security settings (like copy restrictions or printing restrictions) when processing unencrypted PDFs, so if your original had those settings, the processed PDF will maintain them (though these settings can be removed by recipients with appropriate tools, so they should not be relied upon for true security—only password encryption provides real protection).

The comparison involves trade-offs between convenience, privacy, cost, and feature depth—different tools suit different needs rather than one being universally "better." Our browser-based tool excels at: instant availability (no software download, installation, or updates required), absolute privacy (files never leave your device, no server uploads), zero cost (no subscription, one-time purchase, or per-use fees), simplicity (intuitive interface with no learning curve), and cross-platform compatibility (works on Windows, Mac, Linux, ChromeOS, even tablets and phones with modern browsers). For straightforward page removal tasks—deleting blank pages, removing confidential sections, extracting specific pages—it provides fast, effective results in seconds without any software commitment. Adobe Acrobat Pro ($20-30/month subscription or $200+ perpetual license) and similar desktop editors provide advantages in: advanced features (batch processing hundreds of files, OCR for scanned documents, comprehensive editing, form creation, advanced security options), no file size limits (can handle multi-gigabyte PDFs), enhanced performance (faster processing of very large documents using native code rather than JavaScript), and sophisticated page manipulation (rotating, reordering, inserting pages from other documents, splitting by bookmarks). Desktop software also handles edge cases better: automatic renumbering of page references, table of contents regeneration, and advanced link management. For professionals who manipulate PDFs daily (legal staff, publishing professionals, document management specialists), need batch processing capabilities, or work with extremely large or complex documents, commercial desktop software provides productivity justification for the subscription cost. For occasional users who remove pages a few times monthly, individuals who need absolute privacy for sensitive documents, teams who want to avoid per-user licensing costs, or anyone working on managed/locked-down computers where software installation is not permitted, the free browser-based tool delivers sufficient functionality without ongoing costs or administrative overhead. Alternative options include: free desktop tools like PDFtk or PDF-XChange Editor free version (more features than browser tools but require installation and have steeper learning curves), online server-based tools like Smallpdf or iLovePDF (similar convenience to ours but require uploading files, raising privacy concerns), built-in OS tools like Preview on Mac (free and capable but Mac-only), and command-line tools like Ghostscript (powerful and free but require technical expertise). The decision factors: How often do you need page removal? (daily professional use → consider paid software; occasional use → browser tool works), How sensitive are your documents? (confidential materials requiring absolute privacy → browser-based essential; public documents → any option works), What is your budget? (no budget → browser tool; professional budget → evaluate subscription ROI), and What is your technical comfort? (prefer simple visual interfaces → browser tool; comfortable with command-line → consider open-source tools). Many users adopt a hybrid approach: use our free browser tool as the go-to solution for routine page removal and sensitive documents, while maintaining an Acrobat subscription or desktop tool for specialized tasks like batch processing, complex document assembly, or advanced editing that browser tools cannot handle. The key insight is that "better" depends entirely on your specific needs—a free instant tool that absolutely protects privacy might be far better for someone handling confidential legal documents than a feature-rich commercial tool that requires uploading files to servers, even though the commercial tool has more capabilities.
