Free Audio Converter

An audio converter changes a sound file from one format to another so it plays or imports where you need it. This one outputs MP3 or WAV and can read most common audio and video formats. The conversion happens in your browser.

1. Click Choose files and pick your audio or video. 2. Set Output format to MP3. 3. Click Process audio. 4. Play the result and click Download.

Pick MP3 when you want a small file to share, upload or play on any device. Pick WAV when you plan to edit the audio in a program like Audacity or a video editor and file size doesn’t matter. WAV output takes roughly 10 MB per minute.

No. FFmpeg runs inside your browser, reads the file from your device and writes the converted copy there. The engine is downloaded once from a public CDN and then cached.

The converter is free, with no watermark and no daily limit. Each file can be up to 100 MB and 10 minutes long, and you convert one file at a time.

Yes, in current Safari, Chrome and other modern mobile browsers. Larger files take longer on phones, and a computer is more reliable for files near the 100 MB limit.

Common causes are a file over 100 MB or 10 minutes, a video with no audio track, a damaged file or a protected format. A dropped connection during the first engine download can also stop it, so reload the page and try again.
