Questions
Which format should I pick?
M4A when the video's sound is AAC, as in nearly every phone video, because the sound is copied exactly as it is, in seconds. MP3 when you need a file every player and old device opens. WAV for editing, as it is uncompressed (and about ten times larger).
Are my videos uploaded?
No. Your files are processed on your device. We never upload them.
Does M4A lose quality?
Not when the video's sound is AAC; it is copied without change. Sound in other formats (Opus in WebM, for example) is converted to AAC.
Why doesn't MP3 work in my browser?
Saving as MP3 or WAV means decoding the sound, which needs WebCodecs audio. Safari has it from version 26; Chrome, Edge, and Firefox have it. M4A from AAC sound works in every browser.
