// How it works

Three steps. Zero uploads.

01
Drop
Drag your PDF onto the page. It stays on your device.
02
Place
Add signatures, initials, text, dates, or ticks. Drag to position, resize as needed.
03
Export
Download a flattened signed PDF with an audit receipt. Nothing was ever uploaded.
// Why this is different

Your document never leaves your machine.

DocuSign routes your contract through their servers. Adobe Sign does the same. fwip processes everything locally.

fwip works differently. The signing 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.

Is an electronic signature legally valid?▾
In most jurisdictions, yes. Australia's Electronic Transactions Act, the US ESIGN Act, and the EU eIDAS regulation all recognise electronic signatures for most documents.
What's the difference between this and Sign PDF?▾
Smart Sign adds support for initials, text fields, dates, ticks, and an audit receipt. It's the full e-signature workflow vs a simple signature placement.
Can I save my signature for reuse?▾
Yes. Check "Save for next time" and your signature is stored in your browser's local storage. It persists between sessions.
What is the audit receipt?▾
A text file downloaded alongside your signed PDF. It contains SHA-256 hashes of both the original and signed documents, a timestamp, and a summary of placed fields. It provides a verifiable record that the document was signed.
