// How it works

Three steps. Zero uploads.

01
Drop
Drag your files onto the page. Any file type is supported. They stay on your device.
02
Configure
Set your renaming rules — prefix, suffix, numbering, dates, or find & replace. Preview the results live.
03
Download
Download the renamed files as a ZIP. Nothing was ever uploaded.
// Why this is different

Your files never leave your machine.

Most batch rename tools require a desktop app install or uploading files to a server. fwip renames everything in your browser with zero downloads and zero uploads.

fwip works differently. The rename engine runs entirely in your browser. Your data 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.

How do I batch rename files without uploading?▾
Drop your files into fwip. Set a prefix, add dates, or use find & replace. Files are renamed entirely in your browser and never uploaded.
What renaming options does fwip support?▾
Prefix/suffix, sequential numbering, date stamps, find & replace with regex support, and case conversion (upper, lower, title).
Can I preview the new filenames before renaming?▾
