MP3 Reverse
Use MP3 Reverse, review the result, and keep the original until the output is checked.
How to use MP3 Reverse
- Select one or more .mp3 files.
- Press Play on the Original Audio and Processed Audio players to compare the two directions.
- Use Reverse MP3 to build the reversed copy.
- Download each <name>_reversed file; a range can be typed in seconds if only part of the track should turn around.
What MP3 Reverse actually does to your file
Reversal works on decoded samples, so the audio is played backwards exactly - nothing about the pitch or length changes. What you get back depends on Output Format: WAV is written as uncompressed PCM and comes out many times larger than the MP3 you loaded, while MP3 and OGG are encoded at the bitrate chosen in Output Quality, so they land close to the size of the original. Listen before you publish, because most recordings end on a decaying tail that becomes an abrupt rise when flipped.
MP3 Reverse FAQ
What does MP3 Reverse do?
Reverse a supported audio file in your browser. Review the backwards preview and download the processed track.
Which files work with MP3 Reverse?
This category commonly supports MP3, WAV, AAC, OGG, and M4A. Use the accepted file types shown in the uploader, because support varies by browser and by the engine behind each tool.
Does this change the file quality?
Any change that alters the samples forces a re-encode, so quality depends on the export settings you pick. If you only need the same audio in another container, choose a setting that does not re-encode.
Will my original file be changed?
No. The work is done on a copy in this tab by your browser's audio decoder and a WebAssembly build of ffmpeg, and the result arrives as a separate download, so your original is still there if you need it.
How is my file processed?
It is not uploaded. The processing is done locally by your browser's audio decoder and a WebAssembly build of ffmpeg, so the practical ceiling is your device's memory and the limit shown beside the uploader - no queue, no account, no copy on a server.
Is the MP3 Reverse free?
Yes. The MP3 Reverse is free with no trial limit, subscription, or watermark on downloads. You can use it for personal and commercial projects without creating an account.
