What audio formats are supported?

This tool supports MP3, WAV, AAC, OGG (Vorbis), FLAC, and M4A. You can convert from any of these formats to any other.

What bitrate should I choose?

128kbps is acceptable for speech. 192kbps is good for general music. 256kbps is high quality. 320kbps is the maximum for MP3 and offers near-CD quality.

Is FLAC better than MP3?

FLAC is lossless (no quality loss) but creates larger files. MP3 is lossy but much smaller. Use FLAC for archival and MP3 for everyday listening or sharing.

Does conversion happen on a server?

No, all audio conversion happens in your browser using ffmpeg.wasm (WebAssembly). Your files never leave your device — it's completely private.

Can I convert large audio files?

Yes, most audio files convert quickly. Files up to 100MB work well in-browser. Very large files may take longer due to browser memory limits.
