About FreeConversion
Why we built a PDF tool that never sees your files.
Who We Are
FreeConversion was founded in 2023 by Jonathan Beauchemin, a web developer based in Quebec City, Canada. The tool is entirely built and maintained by Jonathan, with a single mission: make PDF compression genuinely free, fast, and private.
The problem that started everything
A few years ago, I needed to compress a PDF before sending it by email. I Googled "free PDF compressor", clicked the first result, and uploaded my file without thinking twice. The compression worked fine. Then I started wondering: where did that file actually go? Which server processed it? How long was it stored? Who had access to it?
I had no answers — and neither did the tools I was using. Their privacy policies were vague at best. Some didn't even have one. For personal documents, that's unsettling. For business contracts, invoices, or anything remotely sensitive, it's a real risk.
Why WebAssembly changes everything
Modern browsers are remarkably powerful. WebAssembly — a low-level bytecode format supported by every major browser since 2017 — lets you run compiled C++ code at near-native speed, entirely on the user's machine. That meant it was technically possible to compress a PDF without sending it anywhere.
FreeConversion was built around that idea. When you drop a PDF onto our tool, it is processed by a WebAssembly module running inside your own browser tab. Nothing leaves your device. Our servers never see your file — not a byte of it. The network request log stays empty.
Free, and staying free
We keep FreeConversion free because PDF compression should not cost money. The tool is ad-supported, which covers infrastructure costs without putting your documents at risk. No subscription, no account required, no file size limits. Open the page, compress your file, close the tab. That's it.
What we are building toward
PDF compression was the starting point. We are gradually adding other document tools — PDF merging, format conversion, and more — all following the same rule: if it can be done locally, it will be done locally. We believe that "free online tool" and "privacy-respecting" should not be mutually exclusive.
