About FormatSwitch.

A small, free toolbox for the everyday file chores no one wants to think about. Merge a few PDFs. Compress a heavy photo. Turn a HEIC into a normal JPG. Done.

It runs entirely in your browser — there's no upload step, no signup, no watermark, and no "pro" tier hiding the good features. The project is supported by donations from people who find it useful.

Why browser-only

Most online converters upload your files to their servers, keep them for a while, and hope you trust their privacy policy. FormatSwitch takes a simpler route: your file never leaves your device. Every conversion happens right in the tab, using WebAssembly builds of the same libraries desktop apps rely on — pdf-lib, PDF.js, Tesseract, and the browser's built-in Canvas encoders.

That means no waiting for uploads on a slow connection, no size limits imposed by a server, and — most importantly — nothing to leak. A merged contract, a scanned passport, an OCR'd medical form: none of it touches a network.

Who's behind it

FormatSwitch is designed and developed by Muktikanta Ojha from India. It started as a personal itch — needing to convert a folder of HEIC photos without handing them to a random website — and grew into the tool you're using now.

There is no company behind the site, no VC funding, and no plans to add a paywall. Growth is deliberately slow: a new tool ships only when it's genuinely useful and can run locally without shortcuts.

How it stays free

The site runs on cheap static hosting because all the heavy work happens in your browser. When someone finds it useful and chips in via UPI, that covers the domain, the hosting, and a coffee for whoever fixed the last bug.

No trackers, no analytics, no cookies. If a tool is missing or something breaks, we'd love to hear from you on the feedback page. The site will grow slowly and stay quiet.
