Browse by Category

Each category varies in size depending on the scope of tools it covers. Image Tools and PDF Tools tend to have the most tools because those file types support many different operations (resizing, compressing, converting, splitting, merging, etc.). Developer Tools and Text Tools also have substantial collections because developers and writers have diverse needs.

Business Tools and Calculators are more focused, containing tools that solve specific calculation needs like GST, profit margins, EMI payments, and discount percentages. SEO Tools is currently our smallest category, but we are actively adding more utilities for content creators and marketers.

The exact count appears on each category page and on this page in the header stats. We regularly add new tools based on user requests and common workflows we identify, so these numbers grow over time.

Yes. Every tool in every category is completely free to use, with no usage limits, no file size caps (beyond what your browser can handle), and no paywalls hiding "premium features." There are no freemium tiers, no trial periods, and no hidden costs. We display Google AdSense ads to cover hosting costs, but the tools themselves are not monetized.

This applies to all categories—whether you are compressing thousands of images in Image Tools, merging hundreds of pages in PDF Tools, or running complex calculations in Business Tools, there are no charges or restrictions.

We built this site because we got tired of finding "free" tools that turned out to require paid accounts for basic functionality. If we ever changed this model (we have no plans to), we would announce it prominently and grandfather in existing users. For now and the foreseeable future, everything is free.

You do not need an account at all—not for any category, not for any tool. This is not a situation where Image Tools are free but PDF Tools require registration. You can use every tool in every category without creating an account, providing an email address, or logging in.

This design choice has privacy and practical benefits. It means you can bookmark individual tools, share links with colleagues, or use our utilities on public computers without worrying about account management. It also means we do not have access to any personal information about you beyond aggregate analytics (like "someone visited the Image Compressor tool" without knowing who that someone was).

Some users initially assume there must be an account system because most modern web services require one. There is not. Just open the tool and use it.

Absolutely, and this is a common workflow. For example, you might use Image Resizer from the Image Tools category to resize a photo, then use Image Compressor from the same category to reduce file size, and finally use Word to PDF Converter from the Text Tools category to embed that image in a document.

Or you might use PDF Splitter to extract specific pages from a large PDF, then use PDF Compressor to reduce the file size, and finally use Image Converter to turn those PDF pages into JPG images for a presentation.

The categories are organizational convenience, not technical barriers. All our tools process files locally in your browser, so you can chain together operations from different categories in whatever sequence your workflow requires. Download the output from one tool, then upload it to another—no server-side integration needed because there is no server-side processing happening.

Category size reflects both the technical complexity of the file type and the diversity of operations people commonly need to perform. Image Tools and PDF Tools are large because images and PDFs support many operations: you can resize, compress, convert, crop, rotate, flip, merge, split, watermark, and more.

In contrast, Business Tools is smaller not because business needs are less important, but because business calculations tend to be more focused: you calculate GST, profit margins, discounts, commissions, etc. Each tool serves a specific purpose, but there are fewer distinct operations compared to the dozens of ways you might manipulate an image.

Developer Tools could theoretically be enormous because developers need hundreds of utilities, but we focus on the most common tasks: encoding/decoding (Base64, URL, JWT), formatting (JSON, code), generating (UUID, hashes), and testing (regex). We prioritize breadth across categories over exhaustive depth in one category.

We also grow categories based on user requests. If we receive many requests for a certain type of tool, we add it. So category sizes partly reflect what people actually ask for, not just what is technically possible.

Yes, all our tools across all categories are designed to work on modern mobile browsers (Safari on iOS, Chrome on Android). The user interface adapts to smaller screens using responsive design, and the file processing logic runs in the mobile browser's JavaScript engine just like it does on desktop.

That said, some tools are more practical on mobile than others. Text Tools and Calculators work great on phones because you are mostly typing and reading. Developer Tools like JSON Formatter or Hash Generator also work well since they handle text input.

Image Tools and PDF Tools work on mobile, but the experience depends on your workflow. If you are compressing a photo you just took with your phone's camera, that is seamless. If you need to crop an image precisely or merge multiple PDFs, a larger screen and mouse/trackpad might be more comfortable.

The technical capability is there across all categories—the practical usability varies based on the task complexity and your device's screen size. We do not artificially restrict any tools from working on mobile; the browser handles it.

We make these decisions based on three factors: user requests, analytics data, and our own workflow needs. If we receive multiple requests for a certain type of tool (say, audio editing or spreadsheet utilities), we evaluate whether it fits our model of client-side processing and whether we can build it reliably in JavaScript.

Analytics helps us identify gaps. If we see high traffic to a tool page with a "coming soon" note, or if users frequently search for a tool type we do not offer, that signals demand. We also look at which tools get used together—if people frequently move from Image Tools to PDF Tools, we might add image-to-PDF converters or PDF-to-image splitters.

Finally, we build tools we would use ourselves. The site started because we needed to merge PDF invoices late on a Sunday night and did not want to upload them to a random website. When we encounter a similar pain point—needing a specific calculator, text utility, or file converter—we add it.

We are a small team, so we prioritize based on impact (how many people will benefit?) and feasibility (can we build it client-side with reasonable performance?). If you have suggestions, contact us—we genuinely read and consider every request.

Not at the moment—we have designed our category structure to be comprehensive enough that every tool has a logical home. However, we recognize that some tools could arguably fit into multiple categories. For example, is a "Word to PDF Converter" a Text Tool or a PDF Tool? We placed it in Text Tools because the input is a text document, but it could work in PDF Tools too.

In cases like this, we use the "Related Tools" feature to surface relevant utilities from other categories. So even if a tool is categorized one way, you will see suggestions for related tools from other categories when you use it.

If we add a tool that genuinely does not fit our existing categories—like an audio editor or video converter—we would create a new category rather than force it into an inappropriate bucket. Our goal is for the category structure to help people find tools intuitively, not to constrain what we can build.

The All Tools page also exists as a catch-all, showing every utility regardless of category. So even if categorization is imperfect, you can always browse the full list.
