// How it works

Three steps. Zero uploads.

01
Drop
Drag your PDF onto the page. It stays on your device.
02
Flatten
Form fields, annotations, and layers are baked into each page at 150 DPI. No server involved.
03
Download
Save the flattened PDF. Nothing was ever uploaded.
// Why this is different

Your PDF never leaves your machine.

Most online flattening tools upload your document to a remote server, rasterise it there, and send back the result. Your forms, signatures, and annotations pass through infrastructure you cannot audit.

fwip works differently. The flattening engine runs entirely in your browser. Your PDF 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.

What does it mean to flatten a PDF?▾
Flattening renders every layer of a PDF — form fields, annotations, comments, and interactive elements — into static page content. The result looks identical but nothing is editable. fwip does this entirely in your browser.
How do I flatten a PDF without uploading it?▾
Drop your PDF onto fwip. Each page is rendered at 150 DPI and reassembled into a clean, non-editable PDF. The entire process runs locally in your browser. No server is involved.
Why would I need to flatten a PDF before sharing?▾
Flattening ensures the recipient sees exactly what you see. It prevents accidental edits to form fields, hides underlying layers, and avoids rendering differences across PDF readers. It is especially useful before printing or archiving.
Does flattening a PDF change the file size?▾
It depends on the content. PDFs with many vector elements or embedded fonts may grow slightly since pages become raster images. Image-heavy PDFs often stay about the same size or shrink.
