Audio Converter
Convert audio between MP3, WAV, AAC, and OGG formats, right in your browser.
Different audio formats serve different purposes — MP3 for broad compatibility and small size, WAV for uncompressed quality needed in audio editing, AAC for efficient quality at low bitrates (common on Apple devices), and OGG as an open-format alternative — and moving between them is a recurring need whenever a file arrives in a format your target software or device doesn't handle.
This converter transforms audio between all four formats using a genuine ffmpeg engine running in your browser via WebAssembly, the same underlying technology behind professional desktop conversion tools. Select your source file and target format, and get a properly encoded result — not a simple container swap, but a real re-encode using each format's appropriate codec (MP3 via LAME, AAC via ffmpeg's native encoder, OGG via Vorbis).
Everything processes entirely on your device, so your audio is never uploaded to a server during conversion.

Frequently asked questions
Common mistakes to avoid
- Converting between two lossy formats multiple times, which compounds quality loss with each re-encode.
- Expecting WAV output to be small — uncompressed WAV files are significantly larger than any compressed format.
