Frequently asked questions
Is my file uploaded to a server?
No. The converter (FFmpeg compiled to WebAssembly) runs inside your browser, so the file never leaves your device. That also means there is no upload wait, even for big videos.
WAV or FLAC?
Both are lossless. WAV is the most compatible; FLAC is about half the size. Pick FLAC if your editor supports it.
Will the audio stay in sync with the video?
Yes. The WAV starts at the same point as the video, so you can line it back up in your editor.
