About the Free Audio Converter: Video, WAV, M4A to MP3
Completely free: free account, no credits, no limit. It runs in your browser, so your audio stays on your device.
The Audio Converter turns any file your browser can play into an MP3 (128, 192 or 320 kbps) or a WAV. That includes the sound of MP4, MOV and WEBM videos, so it doubles as a free video-to-MP3 converter.
Unlike most online converters, the file is never uploaded: it is decoded and re-encoded on your device, so private recordings stay private and big files don’t wait in a queue.
Converting a low-quality file to a higher bitrate can’t add quality back. Song tags and cover art are not copied to the new file.
What you can use it for
- ✓Extract the audio from a video as MP3
- ✓Make a WAV smaller to share it
- ✓Turn M4A voice memos into MP3
- ✓Convert MP3 to WAV for an editor that needs WAV

Frequently asked questions
Which formats can I convert?
+
Anything your browser can play: MP3, WAV, M4A/AAC, FLAC, OGG and the audio of MP4, MOV and WEBM videos. Safari and Chrome support slightly different sets; if one fails, try the other browser.
Which MP3 quality should I choose?
+
192 kbps is a good default. Choose 320 kbps for music you care about, 128 kbps for speech or to keep files small.
Can I convert a YouTube link?
+
No. It converts files on your device. Downloading from YouTube breaks its terms.
Is there a file size limit?
+
Up to 100 MB per file, because the whole file is converted in your browser’s memory.
Is it really free?
+
Yes. It is completely free, with a free account: no limit and no watermark. It runs in your browser, so your audio stays on your device.
