Audio Converter

Converting between MP3, WAV, and OGG runs locally in your browser via ffmpeg.wasm — nothing gets uploaded. The first time you use it, the conversion engine (~30 MB) downloads once; later conversions will be faster.
Click or drag & drop audio (MP3, WAV, OGG, FLAC, and more)

Frequently asked questions

Does audio quality drop during conversion?

It depends on the formats: converting between lossy formats (like re-encoding MP3 at a different bitrate) can reduce quality slightly; converting to a lossless format (WAV) keeps the original quality.

Does the file get processed on a server?

No, the whole conversion runs locally in your browser via WebAssembly — the audio file never leaves your device.
