A free, fast, and privacy-first suite of 43 online file processing tools
FileTools was created to solve a frustrating problem: most online file conversion tools are slow, cluttered with intrusive ads, require account signups for basic features, or quietly store your data on their servers. We believed there had to be a better way — a place where anyone could process files quickly, without paying with their privacy or their patience.
Our mission is simple: provide free, professional-grade file processing tools that work instantly in your browser, respect your data, and never put barriers between you and getting your work done. Whether you're a developer handling API data exports, a designer compressing images for the web, a student converting research files, or someone who just needs to merge a few PDFs — FileTools is built for you.
FileTools provides 43 distinct tools organized into five practical categories, covering the file processing needs most people encounter in daily work:
Every tool is documented with a complete guide explaining what it does, when to use it, and how it works. We invest heavily in clear, helpful content because we believe a good tool isn't just code — it's a tool that teaches you how to use it well.

FileTools is built with industry-standard, open-source technologies known for reliability and performance. We deploy on a hardened Linux server with monitoring, automated backups, and best-in-class security practices.
For browser-side tools we use JavaScript's native APIs (Web Crypto API, FileReader, Canvas, JSON.parse) to ensure the highest level of privacy and the fastest possible response times. Nothing leaves your device when it doesn't need to.
FileTools accepts files up to the following sizes — generous limits that cover the vast majority of real-world use cases:
If you need to process files larger than these limits, our CSV Splitter and PDF Splitter tools can break them into manageable chunks first.
Running and maintaining 43 tools, hosting infrastructure, SSL certificates, and bandwidth costs money. We support FileTools through two transparent revenue streams:
We will always keep all 43 tools free for everyone. There is no premium tier, no paywall, no signup-to-unlock. The tools work for you whether you support us or not.
FileTools is designed to load fast and work everywhere. The interface uses minimal JavaScript, system fonts where possible, and progressive enhancement so the tools function even on slower connections. Every page is responsive — tools work on phones, tablets, laptops, and desktops without any device-specific app or extension.
We also prioritize accessibility: semantic HTML, proper ARIA labels where needed, keyboard navigation, and high-contrast text. Our goal is for FileTools to be usable by anyone, anywhere, on any device.
We genuinely care about user feedback. If you have a feature request, bug report, suggestion for a new tool, or just want to say hi, we'd love to hear from you. Visit our contact page to send us a message — we read every one and reply to as many as we can.
Thank you for using FileTools. Whether you're here for a quick file conversion or you've made us part of your daily workflow, we appreciate your trust. Now go get that file processed.
