Audio editing FAQ
Can it extract audio from video?
Yes. When ffmpeg.wasm can read the video, the first audio track is used.
Are files uploaded?
No. Decoding, trimming, merging, and encoding run locally.
Why is the first conversion slower?
The open-source ffmpeg.wasm engine must load once and is then reused on the page.
