Every "we care about your privacy" page on the internet is a promise. This one is a procedure — 30 seconds, no expertise needed.

1. 1 · Open the Network tab

   Press F12 (or ⌥⌘I on a Mac), switch to Network, and leave it open.

2. 2 · Process a real video

   Go to Compress or Trim, drop a file — the bigger the better — and run the job to completion.

3. 3 · Read the evidence

   You'll see the page's own assets load (HTML, JS, fonts) — and then nothing while your 2 GB file processes. No POST, no PUT, no WebSocket streaming your footage anywhere. There is no server that could receive it.

4. 4 · The airplane-mode version

   Load a tool page, then turn Wi-Fi off entirely. Drop a file. It still works — decoding, encoding and saving are your device talking to itself.

How it actually works

Modern browsers ship the same hardware video encoders that native apps use (the WebCodecs API). LocalVid reads your file from disk in small chunks, decodes and re-encodes on your GPU/CPU, and writes the result back to disk. The only network traffic this site ever makes: loading the page itself, license checks for Pro (a key and an anonymous device hash — never file data), and an optional anonymous page-view beacon you can block without breaking anything.

Compare that with upload-based tools: your NDA'd client footage sits on their servers with a "deleted after 1 hour" pinky-promise, and the 2025 CapCut terms famously claimed a perpetual license over uploads. Structural privacy beats policy privacy — a server that never gets the file can't leak, sell, train on, or be subpoenaed for it.
