Sign PDF Support

Sign a PDF from Mail or WhatsApp

1. Tap the PDF attachment to open it.
2. Tap the Share button, then Sign PDF in the list of actions. If it is not there, scroll to the end of the list, tap Edit Actions, and add Sign PDF.
3. Tap the line to sign. Tap Done: the share sheet opens with the signed copy. Send it in WhatsApp, attach it in Mail, or save it to Files.

You can also tap Sign PDF in the row of apps at the top of the share sheet: the document opens in the app instead.

How placing works

As in Markup: every tool places one thing, then switches off.

• Sign: tap on or just above a line. Your signature snaps onto it at a size that fits; with no line nearby it goes where you tapped. Sign is on when a document opens; tap Sign again for the next signature.
• Initials: the same, with your initials.
• Text: tap where the text goes, then pick today's date, your name, email, phone or address, or type anything. If it is too long for the line, the app says so.
• Check: tap a box; the tick lands in the box.
• What you place is selected right away, with a dot at each corner: drag it to move it (onto another page too), drag a dot to make it bigger or smaller, or tap Remove. Tap the page elsewhere to deselect. A quick flick, or a drag that starts anywhere else, scrolls the page. With no tool on, double-tap zooms.
• Pressing a tool that is already on keeps it on.
• Undo takes back the last step. It never turns a tool on, so your next tap on the page places nothing.
• When you tap Done with marks on more than one page, the app first shows where they are, so nothing goes out by mistake.
• Nothing is filled in by itself: no date or initials appear unless you place them.

Scanning paper

Tap Scan paper. The first time, the app explains why it needs the camera, then iOS asks. If you said no, turn it on in the iPhone Settings app › Apps › Sign PDF › Camera. Opening PDFs from Files and other apps works without the camera.

Change my signature

On the app's Home screen, tap Profile, then Signature or Initials, and draw again (or tap Type instead).

Pricing

• Your first 3 signed documents are free, with no watermark. The sample lease does not count, and sharing the same document again does not count twice.
• After that, Pro signs everything: Pro Yearly with a one-week free trial, Pro Monthly, or Pro Lifetime, a one-time purchase. Prices are shown in the app in your currency.
• Purchases can only be made in the app, not from the share sheet. Once you have Pro, the share-sheet action knows it too.

Restore, manage or cancel Pro

To restore a purchase on a new iPhone, open the app, tap Profile, then Restore Purchases. To manage or cancel a subscription, open the iPhone Settings app, tap your name, then Subscriptions, or tap Manage subscription in the app's Profile. Cancel at least 24 hours before the period ends to avoid renewal. Refunds are handled by Apple at reportaproblem.apple.com.

Is my signature legally binding?

Sign PDF puts your own signature on a document, as signing the paper by hand would. Whether a particular document can be signed this way depends on who asked you to sign it and on local law. The app is not a certified digital-signature service.

Privacy

The app never uploads your documents or signature. The app sends anonymous step counts (no content, names, file names or signatures), which you can turn off in Profile. Read the privacy policy.
