Your audio never leaves your machine.

Most online audio trimmers upload your file to a remote server, trim it there, and send back the result. Your audio passes through systems you don't control.

fwip works differently. The trim 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.

No account required

Drop a file. Get a result. No sign-up, no email, no password.

No subscription

Free in the browser. $99 once for the offline bundle. That's it. Forever.

The desktop version works with no internet connection at all.

Frequently asked.

How do I trim an audio file without uploading?
Drop your audio file into fwip and use the waveform editor to set start and end points. The trim runs entirely in your browser using ffmpeg.wasm. Your file never leaves your device.
What audio formats can I trim?
fwip supports MP3, WAV, FLAC, OGG, M4A, AAC, AIFF, and WMA. The output format matches your input.
Does trimming audio reduce quality?
No. fwip uses stream copy mode when possible, which trims without re-encoding. The audio quality is preserved exactly.
