How to sign a PDF without printing it
Updated July 2026
The old routine — print the PDF, sign it with a pen, scan or photograph it, email it back — wastes twenty minutes and produces a blurry, crooked page. Every part of it is replaceable. Here’s how to sign a PDF without printing anything, wherever you are.
(No scanner either? The same phone replaces both — see how to sign a document without a printer or scanner.)
(Started from paper rather than a PDF? That’s a slightly different job — see how to sign a scanned document on iPhone.)
On an iPhone or iPad
The fastest path if the document is in your email right now:
- Built-in: open the PDF → Markup (pen icon) → + → Signature → draw with your finger → place it → Done. Fine for a one-off.
- With a signature app: Signed keeps a saved signature (drawn or AI-generated) ready to place, auto-fills the date, handles initials and text fields, and exports a flattened PDF — the signature becomes part of the page instead of a floating annotation someone could remove. Import → tap → Finish → share back. Under a minute.

Signing on a tablet with a stylus? The result is a lot closer to your real ink — see how to sign a PDF on iPad with Apple Pencil.
On a Mac
Open the PDF in Preview → click the Markup toolbar → Signature → create one with the trackpad or by holding a signed piece of paper up to the camera. Preview saves it for reuse. Place, resize, export.
On Windows
Adobe Acrobat Reader (free) → Fill & Sign → draw or type a signature → place it. Or open the PDF in Microsoft Edge, which has a built-in draw tool for quick scribbles.
No matter the platform: get a decent signature first
A rushed mouse-scribble looks worse than your pen signature ever did. Two fixes:
- Draw it big in our free signature generator (browser-only, nothing uploaded) and download a transparent PNG you can reuse forever.
- Or type your name and pick one of 15 handwriting styles — see your name rendered in each on the cursive signature pages.
Is a PDF signed this way “real”?
For the everyday documents this guide is about — leases, permission slips, freelance contracts, waivers, offer letters — a signature image placed on the PDF is the standard way these get signed in practice, and it’s what the sender expects when they email you a PDF. The honest caveats:
- Whether any signature (ink included) is legally binding depends on your jurisdiction, the document type, and the parties’ agreement.
- For high-stakes documents — deeds, court filings, notarized instruments — ask a lawyer or use a certified e-signature service with identity verification.
- Prefer a flattened export (the signature merged into the page) over a floating annotation, so it can’t be moved or deleted downstream.
The 60-second version
Email arrives → open the PDF in Signed → tap the signature line → your saved signature + today’s date drop in → Finish → reply with the signed copy. Printer stays off.

Signing it in the app it arrived in
Most paperwork turns up as an attachment in something — mail, a chat, a cloud drive. These walk through getting the file out of that app, signed, and sent back, and most of them do it with Apple’s Markup, which is free and already on your iPhone.
