// How it works

Three steps. Zero uploads.

01
Drop
Drag your PDF onto the page. It stays on your device the entire time.
02
Markup
Highlight text, add strikethroughs, or freehand draw on any page. Choose colours, undo freely, and navigate between pages.
03
Download
Save the marked-up PDF. Nothing was ever uploaded.
// Why this is different

Your PDF never leaves your machine.

Most online markup tools upload your document to a server, let you annotate a preview, then process the file remotely. Your content passes through infrastructure you don’t control — for a task your own browser can handle.

fwip works differently. The markup 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 highlight text in a PDF for free?▾
Drop your PDF onto fwip and select the Highlight tool. Draw over the text you want to highlight. You can choose from four colours. Everything runs in your browser with no upload required.
Can I draw on a PDF without Adobe?▾
Yes. fwip lets you highlight, strikethrough, and freehand draw on any PDF page directly in your browser. No Adobe subscription or account needed.
How do I mark up a PDF without uploading it?▾
fwip processes the file entirely in your browser. Your PDF is rendered locally, markups are burned into the pages as images, and the result is saved back to your device. No server is involved.
Does marking up a PDF change the original file?▾
fwip creates a new PDF with your markups baked in. The original file on your device is never modified. You download a separate marked-up copy.
