Frequently Asked Questions
Are my media files uploaded?
No. Processing uses ffmpeg.wasm in your browser. Files never leave your device. The first run downloads a ~25MB media engine from a CDN.
Which formats are supported?
Common containers your browser and ffmpeg.wasm can decode. Pick MP4 for widest compatibility.
