Good to know
Picking a format: MP3 is the safe choice that plays anywhere, M4A tends to sound better at the same size, WAV is uncompressed for editing, FLAC keeps the exact sound in less space for archiving, and OGG (Opus) is very efficient at small sizes.
MP3 is the most widely supported audio format. Its lossy compression removes sounds people barely hear, keeping files small, and it plays on virtually every phone, car stereo and speaker.
FLAC is a lossless compressed format. It holds exactly the same sound as WAV in about half the space, making it popular for hi-res music archives, though some phones and car stereos cannot play it.

FAQ
Are my files uploaded?
No. Every conversion runs in your browser on your own device.
Does it work with long videos?
Yes, but it uses your device’s power, so a one-hour video may take a few minutes, and files over 2 GB may fail on phones.
