Frequently asked questions (5)

Is it free?

Yes — completely free, with no sign-up, no watermarks, and no limit on how many files you reverse.

What's reversing audio good for?

Sound design and effects, reverse-cymbal/swoosh transitions, the "say it backwards" challenge, and checking songs for reversed/hidden messages.

Are my files uploaded anywhere?

No. Reversing happens locally in your browser, so your audio never leaves your device.

Does it change the quality?

No — reversing just plays the same samples in the opposite order, so the audio quality is unchanged (saved as MP3 or WAV).

Which formats can I use?

Whatever your browser can decode — MP3 and WAV work everywhere, with M4A, OGG and FLAC where supported.
