All Tools – Free Online Utilities for Everyday Tasks

Images are the most common files people share, publish, and process online, yet they create persistent friction. A product photo taken on a phone is too large to email. A screenshot uploaded to a support portal is rejected because the platform has strict file size limits. A banner image on a website slows down the page, hurting performance and user experience. A logo exported from design software includes transparency, but the destination platform only accepts JPG. These are not edge cases. They happen constantly in professional work, side projects, and everyday communication.

Image tools solve these problems by letting you change dimensions, reduce file size, convert formats, crop to specific aspect ratios, flip or rotate orientation, remove color, add watermarks, inspect embedded metadata, and strip location or camera information before sharing. The most common workflow starts with identifying what broke: if the file is too large, compress or resize. If the format is wrong, convert it. If privacy matters, check the metadata and remove it. If layout is the issue, crop or rotate. Each tool includes a preview so you can verify the result before downloading.

These tools are for developers optimizing web performance, designers preparing assets for consistent layouts, creators publishing to multiple platforms with different requirements, and privacy-conscious users who want to verify that photos do not contain GPS coordinates or timestamps before posting them publicly. Unlike cloud services that require uploads and may store files temporarily, these tools process images directly in your browser. That means your images stay on your device and are not sent anywhere.

PDF files are everywhere because they are portable and preserve formatting across devices and operating systems. But working with PDFs often requires specialized software. You need to merge multiple invoices into one file for accounting. You need to split a long document so you can share only the relevant pages. You need to compress a scanned contract because email attachments have size limits. You need to remove pages from a report before sending it to a client. These are everyday document tasks, yet most built-in PDF viewers do not support editing or transformation.

PDF tools make these operations straightforward. Merge combines multiple PDFs into a single file in the order you choose. Split extracts specific pages or breaks a large PDF into smaller chunks. Compress reduces file size by optimizing images and removing unnecessary data while keeping the document readable. Page removal deletes unwanted pages without affecting the rest of the document. Unlike desktop software that requires installation and licensing, these tools run entirely in the browser. You select files, preview the operation, and download the result. The files are not uploaded to a server, so sensitive documents stay private.

These tools are for business professionals preparing reports, students compiling assignments, freelancers managing invoices, and anyone who regularly works with PDFs but does not want to install heavyweight software or subscribe to a paid service. They handle the most common PDF workflows: combining documents, extracting sections, reducing file size, and removing pages. For documents that do not need advanced editing, these tools provide a fast and private alternative to cloud services.

Developers spend significant time debugging, validating, and transforming data during daily work. An API returns minified JSON that is unreadable without formatting. A JWT token needs to be decoded to inspect its claims. A regex pattern needs to be tested against sample text before deploying it to production. Metadata tags on a page need to be verified for SEO compliance. Structured data needs validation to ensure search engines can parse it correctly. Hash values need to be generated for file integrity checks. These are not major engineering problems, but they interrupt the workflow when you have to find the right tool, install dependencies, or use a third-party service that may log your data.

Developer tools solve these friction points by providing instant, browser-based utilities. JSON formatters pretty-print minified code with proper indentation. JWT decoders extract headers and payloads without requiring server-side validation. Regex testers show real-time matches and capture groups. Meta tag checkers scan a URL and report what search engines and social platforms will see. Structured data validators parse JSON-LD and report errors or warnings. Hash generators create checksums for verifying file integrity. These tools are built for speed: paste or upload data, get the result immediately, and continue working.

These utilities are for frontend developers optimizing pages, backend engineers debugging tokens, SEO specialists validating markup, content creators checking Open Graph tags, and anyone who needs quick access to common data transformations without switching contexts or installing packages. Because the tools run in the browser, they work offline once loaded, and sensitive data like API tokens or private URLs never leave your device.

Running a business, managing finances, or planning purchases involves constant calculations. A seller on an e-commerce platform needs to calculate the net amount after marketplace fees and GST. A customer wants to know the final price after applying a discount. A borrower needs to understand the monthly EMI for a loan. A business owner wants to calculate the selling price that achieves a target profit margin. A freelancer needs to compute GST on invoices. A person tracking health goals needs to calculate BMI. These calculations are not complex, but doing them manually is error-prone and time-consuming, especially when they need to be repeated frequently.

Business and calculator tools provide accurate, instant results for common financial, health, and planning calculations. GST calculators compute tax amounts and net prices based on Indian tax rates. Discount calculators show the final price and savings after applying percentage discounts. EMI calculators break down loan payments into monthly installments with interest. Profit margin calculators determine selling prices that achieve desired margins. Commission calculators compute earnings for sales roles. Marketplace fee estimators show net revenue after platform fees. BMI calculators assess health metrics. These tools eliminate manual errors and provide clear, actionable results.

These calculators are for small business owners managing pricing and taxes, e-commerce sellers calculating net revenue, freelancers preparing invoices, individuals planning loans or purchases, and anyone who needs quick, reliable calculations without spreadsheets or formulas. The tools are designed for Indian business contexts, with support for GST rates and marketplace platforms commonly used in India, but the core calculations apply globally.

1. Identify the problem first. Start by understanding what you need to fix: file size, file format, data validation, calculation, or transformation. This helps you choose the right tool category quickly.
2. Navigate by category or search. If you know the category (image, PDF, developer, calculator), use the category pages linked in the header. If you are exploring, browse this full tools list. Each tool name describes its purpose clearly.
3. Read the tool page before using it. Every tool includes an explanation of what it does, who should use it, step-by-step instructions, and frequently asked questions. This prevents common mistakes and helps you understand the trade-offs (for example, compression quality versus file size).
4. Upload files or paste data directly. File-based tools like image compressors and PDF mergers require file uploads. Text-based tools like JSON formatters and regex testers accept direct input in text fields. Files are processed locally in your browser, not uploaded to a server.
5. Preview results before downloading. Most tools show a preview of the output so you can verify the result before downloading. For image tools, check the preview at the actual size you will use it. For calculators, verify the numbers match your expectations.
6. Download and verify. After processing, download the result and verify it works as expected in the destination where you will use it. Keep the original file until you confirm the processed version meets your needs.
7. No sign-up or data storage. Tools work immediately without creating an account. Files are processed in your browser and are not stored on any server. Once you close the page, the data is gone. For sensitive files, this is a privacy advantage.
