Three steps. Zero uploads.

01

02
Arrange
Drag files to reorder. Remove any you don't want. Choose your output format.
03
Download
Get the merged audio file instantly. All files combined in order.
// Why this is different

Your audio never leaves your machine.

Most online audio mergers upload all your files to a server. fwip combines them entirely in your browser — your recordings stay private.

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.

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.

Works offline

The desktop version works with no internet connection at all.

// Questions

Frequently asked.

Can I merge different audio formats?▾
Yes. fwip handles mixed formats — you can merge an MP3 with a WAV and an M4A. All files are re-encoded to your chosen output format during the merge.
Does merging re-encode the audio?▾
Yes. To ensure seamless joins between files (especially with different sample rates or codecs), fwip re-encodes all files into the output format. Quality is preserved using high-quality encoding settings.
Is there a limit on how many files I can merge?▾
The free web version can merge as many files as your browser memory allows — typically 20-50 files depending on size. The offline bundle removes all limits.
Can I reorder the files before merging?▾
Yes. Drag files up or down in the list to change the order. You can also remove individual files with the × button.
What output formats are available?▾
MP3 (compressed, smaller file size) and WAV (uncompressed, lossless quality).
