Frequently asked questions
Should I pick MP3 or M4A?
MP3 plays everywhere. M4A (AAC) can usually copy the video's audio without re-encoding — instant and lossless. Pick WAV if you'll import it into an editor.
Which quality should I choose?
128 kbps is plenty for speech, 192 kbps for music, 320 kbps for the highest quality. Nothing can sound better than the source.
Does it work with MOV or WebM?
Yes. It extracts audio from MP4, MOV, M4V, WebM and MKV, and converts audio files (WAV, M4A, OGG) to MP3 too.
Is it really free?
Yes. These tools are completely free — no sign-up, no credits, no watermark. Your file is processed on your device, so it costs us nothing.
Is my file uploaded anywhere?
No. Your file is processed in your browser and never leaves your device. The internet is only used to open the page.
Is there a file limit?
Videos up to 2 GB and 30 minutes. Processing time depends on your device; keep the tab open for long videos.
Which browsers are supported?
Works best in current Chrome, Edge and Opera. Some video tools are limited in Safari and Firefox; a tool tells you clearly when your browser can't run it.
