About this tool
One converter for the common audio formats. Upload MP3, WAV, M4A, AAC, OGG, FLAC or Opus and choose the output: MP3 for compatibility, M4A (AAC) for Apple devices, OGG Vorbis as an open format, WAV for editing, or FLAC for lossless archiving at roughly half the size of WAV. FFmpeg does the conversion on our server.
Frequently asked questions
Does converting to FLAC or WAV improve quality?
No. They are lossless, so they preserve exactly what is in the source — including any loss from an earlier MP3 or AAC encoding.
What do the quality options mean?
Standard: MP3 192 kbps, AAC 160 kbps, Vorbis q5. High: MP3 320 kbps, AAC 256 kbps, Vorbis q8. WAV and FLAC are always lossless.
Is Audio Format Converter private?
Your file is uploaded over an encrypted connection and processed in a private temporary folder on our server. The uploaded file and the result are deleted from the server as soon as processing finishes — whether it succeeds or fails — and the result is sent straight to your browser. If an upload is interrupted part-way, its temporary data is removed automatically within about 30 minutes. We do not keep copies.
