Files are processed in your browser. Nothing is uploaded to a server.
Need a recording as an MP3 for sharing, or an uncompressed WAV for editing? This converter decodes your audio in the browser and re-encodes it to MP3 or WAV. Because everything happens locally, even long voice memos and music files stay completely private.
How to convert audio
- Drop in an audio file your browser can read (MP3, WAV, M4A, OGG and more).
- Choose the output format: MP3 (compact) or WAV (lossless).
- For MP3, pick a bitrate to balance size and quality.
- Click Convert and download the new audio file.
MP3 vs. WAV
| Format | Quality | Size | Best for |
|---|---|---|---|
| MP3 | Very good (lossy) | Small | Sharing, podcasts, music |
| WAV | Perfect (lossless) | Large | Editing, archiving |
Converting a lossy file (like MP3) to WAV will not restore quality already lost; it only changes the container.
Converter features
- Decodes any format your browser supports, exports to MP3 or WAV.
- Selectable MP3 bitrate (e.g. 128, 192, 320 kbps).
- No file-size upload limits imposed by a server.
- 100% local processing — audio never leaves your device.
Frequently asked questions
Why is there no server upload?
Modern browsers can decode and encode audio themselves. Keeping it local is faster for you and far better for privacy.
Which input formats work?
Any format your browser can decode — commonly MP3, WAV, M4A/AAC, OGG and FLAC. Support varies slightly by browser.
Will converting improve quality?
No conversion can add detail that was already discarded. Convert from the highest-quality source you have.
