About weconvert.net

weconvert.net is a privacy-first file conversion service. Every conversion runs entirely inside your browser using open-source libraries.

How it works

When you visit a converter page, your browser downloads a small JavaScript bundle that includes a conversion library compiled to WebAssembly or implemented in pure JS. When you drop a file, that library reads the bytes locally and writes out the converted file. Nothing about the file is sent over the network.

We use established open-source libraries: ffmpeg.wasm for video and audio, PDF.js for PDF, SheetJS for spreadsheets, the native Canvas API for most image formats, and many more.

Why client-side?

Most online converters upload your file to their servers, convert it there, and ask you to trust their privacy policy. That model puts your files on someone else's machine — even if they delete them afterwards.

We do it differently. The whole tool runs on your machine. We never receive your files because there is no server-side conversion path.

What we collect

We use privacy-respecting analytics that does not set cookies or track individuals. See Privacy for details.

Open source

The conversion libraries are open source; the website around them is proprietary for now but built on standards (Next.js, React).

Who makes it

weconvert.net is built and operated by a small independent software company in Prague. We fund it by selling desktop apps — see pricing — which is why the web version can stay free without ads following you around.
