How do I convert audio between formats?

Pick your target format (MP3, WAV, OGG, M4A or FLAC), drop your file, and the converter re-encodes it in your browser. Then download the result.

Is my file uploaded to a server?

No. Conversion runs locally via WebAssembly — your audio never leaves your device. The first conversion loads the audio engine once per visit.

Which formats are supported?

Input: most common audio and video files. Output: MP3, WAV, OGG, M4A/AAC and FLAC.
