About Audio Converter

Different apps, devices, and platforms expect different audio formats — a video editor might want WAV, a podcast host might require MP3, and an archivist might prefer lossless FLAC. Our free audio converter switches your file between MP3, WAV, OGG, AAC, and FLAC in your browser, with a bitrate option so you can balance file size against audio quality for the compressed formats.

Upload your file, choose the output format and bitrate, and download the converted result — no software install, no watermark, and no signup required.

Frequently Asked Questions

1. Which formats can I convert between?

You can upload MP3, WAV, or OGG files and convert to MP3, WAV, OGG, AAC, or FLAC.

2. What bitrate should I choose?

192 kbps is a good default for most listening. Choose 320 kbps for the highest quality on compressed formats, or 128 kbps if you need a smaller file size.

3. Does converting to a lossless format like FLAC restore lost quality?

No — converting a lossy file (like an MP3) to a lossless format doesn't add back detail that was already discarded during the original compression. It's only lossless going forward from that point.
