Frequently asked questions

What can I do with Fillpen?

Open any PDF and fill it in — type into its real form fields, or add text anywhere on the page — then sign it, add stamps like a tick or today's date, mark it up with pen, highlighter and shapes, reorder or rotate pages, and export a flattened copy you can save, share or print. You can also build a PDF from photos and merge several PDFs into one.

Does Fillpen work offline, and is my document private?

Yes. Fillpen does all of its work on your device, so it works offline and your documents never leave your phone unless you choose to save, share or print them. There is no account and nothing is uploaded; the only thing that goes online is the ads that keep the app free.

How do I sign a PDF?

Three ways: draw your signature with a finger, type it in a handwriting style, or import a photo of a signature (the background is removed for you). Saved signatures and initials go in a small library, so next time you just tap to place one, then move, resize or recolour it. The finished copy is flattened, with no watermark.

Is Fillpen free, and does it show ads?

Fillpen is free, with no in-app purchase and nothing to unlock. It is supported by ads, shown on screens like Home and after an export — never while you are filling or signing a document. Where the law requires it, you are asked about ads before any is shown, and you can change that choice at any time in Settings.

Is Fillpen on Android and iPhone?

Fillpen is built for both Android and iPhone, and is coming soon to Google Play and the App Store — this page and its privacy policy are published ahead of the listings.
