How to add a signature to a PDF on iPad

Add signatures to PDFs on iPad in Safari, with finger or Pencil. Save once, stamp on as many pages as you need.

Lease, NDA, school form — anything that arrives as a PDF needs a signature, and the iPad is the natural place to do it. The Pencil makes the signature look real; the big screen makes the document readable.

Getting the signature onto the page shouldn't take ten taps.

Fastest path in Safari

Open Safari. Drag the PDF in from Files or Mail (Split View makes this trivial). Go to Flint's signer, upload the file, tap Add signature. Sign with finger or Pencil. Drop it onto the signature line. Done.

The whole flow is under thirty seconds for a single signature, slightly longer for documents that need initials on every page.

Initials, dates, and fields

Most signed PDFs need more than one mark. Initials on each page, date next to the signature, sometimes a printed name. Flint's signer saves the signature once and lets you stamp it anywhere — and the text tool handles dates and printed names.

If the PDF has form fields, edit the PDF to fill them before signing.

Sharing the signed copy

Once downloaded back to Files, share via Mail, AirDrop to your Mac, or drop into Drive. If the original came from a Mail thread, jumping back to Mail and attaching the signed copy takes two taps.

FAQ

Can I use Apple's Markup signature instead?

Markup signatures work but are tied to the Mail-based signing flow and don't handle multi-page initials gracefully. For one-off finger signatures in Mail, Markup is fine. For anything serious, Flint's flow is faster.

Is the Pencil signature better than finger?

Visually, yes — pressure variation makes the line look like a real signature. Legally, both are equivalent in most jurisdictions. Use whichever feels right; the result is the same legally.

Can I save my signature for next time?

Within a session, yes — the signature stays loaded for the document. Across sessions, Flint deliberately doesn't store signatures for privacy. Each new session, draw it again — twenty seconds.
