// How it works

Three steps. Zero uploads.

01
Drop
Drag your PDF form onto the page. It never leaves your browser.
02
Fill
Type into text fields, tick checkboxes, and select dropdowns — right in the preview.
03
Download
Save your filled PDF. Optionally flatten it so fields can't be edited. Nothing was ever uploaded.
// Why this is different

Your form data never leaves your machine.

Most online form fillers upload your document to a server. That means your personal data — names, addresses, tax details — passes through infrastructure you don't control.

fwip works differently. The form-filling 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.

How do I fill in a PDF form without printing it?▾
Drop your PDF into fwip. The tool detects all fillable fields and lets you type directly into them in your browser. Save and download when done — no printing required.
What does "flatten" mean when filling a PDF form?▾
Flattening burns your typed values into the PDF as fixed text. The fields become uneditable, which prevents accidental changes and ensures the form looks identical on any device.
Can I fill a PDF form without Adobe Acrobat?▾
Yes — fwip fills PDF forms entirely in your browser with no software to install. Acrobat is not required.
What types of form fields does fwip support?▾
Text fields, checkboxes, radio buttons, dropdowns, and list boxes. All standard AcroForm field types are supported.
Is my form data safe when I fill it with fwip?▾
Your file and everything you type stay on your device. There is no server involved, so there is nothing to breach.
