Frequently asked questions
Is my video uploaded to a server?+
No — conversion runs entirely in your browser using a WebAssembly build of FFmpeg. Your file never leaves your device.
Can I use this on YouTube videos?+
This tool only works with video files you upload from your own device. It can't download or convert videos from YouTube or other sites, which would violate their terms of service.
Why does the first conversion take a while?+
The converter engine (~30MB) downloads once and is cached by your browser — later conversions are much faster.
