Questions

Is it free?

Yes. There is no account, watermark or daily limit.

Do you store my files?

No. We don't store your files on our servers or keep a copy of anything you make. These tools are built privacy first.

Which format should I pick?

MP3 plays almost everywhere. M4A sounds slightly better at the same size. WAV and FLAC keep everything, and FLAC is smaller than WAV.

Why is there a 1 GB limit?

It keeps the free tool fast and reliable. On older browsers the limit can be 200 MB. For larger files or automated work, use the MediaTofu API. FLAC files are limited to 200 MB.
