Key features

Nothing is uploaded

The audio is processed by your own device, inside the browser. Your files never leave your computer or phone.

Up to 10 files at once

Drop a whole batch of files at once, up to 500 MB each, and download the results individually (one by one) or all together as a .zip.

Fast

Audio is light work on most devices: most files are processed in just a few seconds, with a progress bar for the longer ones.

Clean sound

A high-quality encoder (LAME for MP3, AAC, Vorbis, Opus, FLAC) at the bitrate you choose. Lossless formats stay lossless.

Simple options

MP3 to M4R asks only for what really matters and uses sensible defaults, so the first result is usually the right one.

Free, no account, no watermark

No sign-up required, no limits on the number of files, nothing extra added on your audio. Just a single ad keeps the site running.
