AVMint
Built on WebAssembly

Privacy First — Your files never leave your browser

Most online video tools upload your files to a server. AVMint doesn't. Every byte of every file you process stays on your device — we cannot see them, store them, or leak them.

Zero uploads

Your files are never sent to any server. There is no upload progress bar because there is no upload — processing starts the instant you drop a file.

Runs on WebAssembly

AVMint compiles ffmpeg to WebAssembly and runs it inside a Web Worker in your browser tab. The same battle-tested codecs, executed locally.

Works offline

Once the page is loaded, you can disconnect from the internet and AVMint will keep working. Try it — turn off Wi-Fi and convert a video.

No accounts, no tracking

No sign up. No file logs. No analytics on your file contents. We do not even know which files you processed.

How does in-browser processing work?

AVMint loads ffmpeg.wasm — a port of the open-source ffmpeg media toolkit compiled to WebAssembly — directly into your browser. WebAssembly is a low-level binary format that runs inside the same JavaScript sandbox as a webpage, at near-native speed.

When you drop a file, the browser hands the file's bytes to the WebAssembly module. ffmpeg decodes, transcodes, compresses or trims the media inside a Web Worker thread, so your tab stays responsive. The result is written back to memory and offered as a download.

At no point in this pipeline is the file copied to a remote server. Your video, your audio, your metadata, your filename — all of it stays on your machine.

Don't trust us — verify it yourself

You don't have to take our word for it. Here is how to confirm AVMint never uploads your files:

  1. Open AVMint's Compress or Convert tool in a new tab.
  2. Open your browser's DevTools (F12 or Cmd+Option+I) and switch to the Network tab. Filter by 'Fetch/XHR'.
  3. Drop a video file and click Compress. Watch the Network tab — you will see ffmpeg.wasm and core files load once, then nothing else. No POST request, no upload, no traffic carrying your file.

If we were uploading your file, you would see it in the Network tab. We are not.
