Audio Converter
Convert audio between MP3, WAV, AAC, FLAC and OGG, or extract the audio from any video, entirely in your browser.
🔒 Your file is processed on your device and never uploaded.
Convert audio between MP3, WAV, AAC, FLAC and OGG, or drop in a video (MP4, MOV, MKV, AVI, WMV, FLV and more) and keep just the soundtrack. The conversion runs inside this page on your own device, so nothing is uploaded and nothing is stored.
That makes it a reasonable choice for recordings you would not want sitting on someone else's server: interviews, voice notes, lecture recordings, unreleased music, or anything covered by a confidentiality agreement.
How to convert audio
- Drop an audio or video file onto the box above, or click it to choose one.
- Pick your output format. MP3 plays everywhere; FLAC and WAV keep full quality at a much larger size.
- Choose a quality preset. This sets the bitrate for compressed formats like MP3, AAC and OGG.
- Click Convert and download the result.
What makes this different
- Extracts audio from video files as well as converting between audio formats.
- Lossless output available: FLAC and WAV preserve the original audio exactly.
- No uploads, no account, no arbitrary length limits, and no watermark or audio tag.
- Works offline once the page has loaded.
Frequently asked questions
- Can I pull the audio out of a video?
- Yes. Drop in an MP4, MOV, MKV, AVI or almost any other video and choose MP3, WAV, AAC, FLAC or OGG as the output. The video is discarded and you get just the soundtrack.
- Which format should I choose?
- MP3 for maximum compatibility, AAC for slightly better quality at the same size, OGG for a good free-format option, and FLAC or WAV when you need lossless audio for archiving or further editing and don't mind the much larger files.
- Does the quality setting affect FLAC and WAV?
- No. Those are lossless formats, so there is no bitrate to trade off; the setting only affects compressed formats like MP3, AAC and OGG.
- Will converting MP3 to MP3 improve the quality?
- No, and it will usually make it slightly worse. Compressed audio loses information permanently, so re-encoding cannot recover it. Convert from the highest-quality source you have.
- Is my audio uploaded anywhere?
- No. Everything happens in your browser. Turn off your Wi-Fi after the page loads and convert a file. It still works, because nothing needs to leave your device.
