- Powered by FFmpeg compiled to WebAssembly — the engine (~31 MB) loads once, on demand, and is cached by your browser.
- Pick a target format, quality preset and optional resolution — progress is shown live with a full log.
- Handles files up to 200 MB. Everything runs locally: your videos are never uploaded, stored or logged.
Video Converter is part of Upwwards Tools, a free collection of browser-based utilities built by the team at Upwwards. Like the rest of the suite, it's free, requires no sign-up, and keeps your data on your device.
