Flip a sound so it plays from the end back to the start — for reverse sound effects, hunting for backmasked messages in songs, meme edits and transitions, or the reverse-singing challenge. Drop in several files to reverse them all at once, or pick a video file to reverse just its sound.

## How to use

1. Upload one or more audio (or video) files
2. Choose the output format and bitrate
3. Click reverse and download the result

## Features

- Whole track reversed sample by sample
- Batch supported
- Reverse the sound straight from a video file
- MP3 / M4A / WAV / FLAC / OGG / OPUS output
- FFmpeg runs locally

## FAQ

### Does reversing lower the quality?

Reversing itself is lossless — it only changes the order of the samples. Choose WAV or FLAC for a bit-perfect result, or 192 kbps or higher if you want MP3.

### How do I reverse only part of a file?

Cut the part you need with the Audio Trimmer first and reverse that, or reverse the whole file and trim it afterwards.

### Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

### Do I need to sign up or pay?

No. The site is completely free, requires no account, has no usage limits and adds no watermarks.
