# tinv

> tinv (tiny video) is a free, open-source tool that compresses ordinary videos into small `.tinv` files — typically 10–50× smaller than the source — using AV1 video and Opus audio, and plays them back in the browser. Nothing is uploaded; there is no account, tracking, or analytics.

- A `.tinv` file is an AV1+Opus video in a small container. It opens only in tinv players (web app, browser extension), not in a plain video player. Title, chapters and compression stats are embedded in the file.
- Convert: the web app encodes short videos in-browser using native WebCodecs AV1 (Chromium browsers: Chrome/Edge). A native Rust command-line tool handles large recordings much faster.
- Play: open a `.tinv` in the web player, or share a link to a hosted file, e.g. `https://tinv.app/?url=https://your-host/lecture.tinv`. Playback works offline once the app is loaded (PWA).
- Price: free. License: open source.
