// Why this is different

Your audio never leaves your machine.

Most online audio tools upload your file to a server. fwip reverses audio entirely in your browser — your file never leaves your device.

fwip works differently. The processing engine runs entirely in your browser. Your audio is read from your device, processed on your CPU, and the result is saved back to your device. No server is involved. We literally cannot see your file.

No server processing

Everything runs on your device using WebAssembly. Your file never touches a network.

The desktop version works with no internet connection at all.

// Questions

Frequently asked.

How does audio reversal work?▾
fwip takes every audio sample in your file and plays them in reverse order. The result is your audio played completely backwards — useful for creative effects, music production, or just fun.
Does reversing affect quality?▾
The audio is re-encoded during reversal, but at the same quality settings as the original. There's no perceptible quality loss.
What formats are supported?▾
MP3, WAV, M4A, OGG, AAC, and FLAC. The output format matches your input.
Can I reverse just part of an audio file?▾
This tool reverses the entire file. To reverse a section, first use fwip's Trim Audio tool to extract the portion you want, then reverse it here.
Does this work offline?▾
After the first load, yes. The audio engine is cached in your browser and works fully offline.
