Frequently asked questions

How much does it cost?

Universal PDF requires a Pro subscription. One subscription unlocks every tool on the site, cancel anytime.

Which audio formats are supported?

This hub converts between MP3, WAV, M4A, FLAC and OGG, and can also extract audio from MP4, MOV and MKV video files. The format picker only enables targets that make sense for your uploaded file, so unsupported combinations are grayed out automatically.

Can I convert several files in one batch?

Not from this page; each upload goes through the picker one file at a time. Repeat the drop-and-convert step for additional files.

Does converting reduce audio quality?

Converting between lossy formats like MP3 and OGG can lose a little quality with each re-encode, since compression is applied again. Converting to or from a lossless format such as WAV or FLAC preserves quality until the file lands on a lossy target.
