Is my audio uploaded anywhere?

No. The reversal runs entirely in your browser, so your audio never leaves your device.

What does reversing audio do?

It flips the order of the sound samples so the clip plays from the end to the beginning — everything you hear is played backwards.

Which audio formats can I reverse?

You can reverse MP3, WAV, M4A, AAC, and OGG files. The output can be saved as MP3 or WAV.

Will reversing reduce the audio quality?

The clip is decoded and re-encoded. Choose WAV for an uncompressed result or MP3 for a smaller, good-quality file.

Can I reverse a track back to normal?

Yes. Reversing an already-reversed file restores the original playback order.

Does it work on mobile?

Yes. It works in modern mobile browsers, though very long files process faster on a desktop.

Yes. There are no watermarks, sign-ups, or file-size limits beyond what your device can handle.
