Audio Converter

Convert audio files between MP3, WAV, OGG and more

The free online audio converter transforms tracks between MP3, WAV, OGG, AAC, FLAC and M4A right inside your browser. Whether you're a podcaster preparing episodes for distribution, a musician archiving lossless masters, or a student converting lecture recordings, you can switch between formats privately and instantly.

MP3 dominates portable players and casual listening, WAV is the gold standard for editing, FLAC preserves studio quality without bloating file size, and OGG and AAC give the best web and mobile compression. With a single tool you can move freely between all of them — no installs, no signups, no servers.

Audio conversion is essential whenever you need cross‑device compatibility, smaller file sizes for streaming, or higher fidelity for editing. By keeping everything client‑side, our converter ensures that confidential interviews, copyrighted music, and unreleased recordings never leak outside your device.

Frequently asked questions

How do I convert MP3 to WAV online?

Upload your MP3 file, select WAV as the output format, choose your desired bitrate, and click Convert. Everything processes in your browser — no uploads needed.

Can I convert FLAC to MP3 without losing quality?

Our converter lets you choose a high bitrate (320kbps) when converting FLAC to MP3 to minimise quality loss. Note that MP3 is lossy, so some quality reduction is expected.

What audio formats does the converter support?

We support MP3, WAV, FLAC, AAC, and OGG as both input and output formats, with bitrate options from 64kbps to 320kbps.

Can I convert multiple audio files at once?

Yes. Upload multiple audio files and they will all be converted to your chosen format simultaneously with batch processing.
