How to add your signature to multiple pages of a PDF on iPhone

Most documents want one signature at the end. Some don’t. A settlement agreement, a multi-part consent form, a contract with a signature block after each section — these ask you to sign in two, three, sometimes half a dozen places across the same PDF.

On an iPhone that’s entirely doable without printing anything. But there’s a specific way it goes wrong that’s worth knowing before you send the file back, because you won’t see it happen.

Option 1: iOS Markup (free, built in)

Apple’s Markup handles multi-page PDFs, and it does let you place a signature on more than one page:

Open the PDF in Files, or tap the attachment in Mail.
Tap the pencil (Markup) icon in the top corner.
Tap + → Signature. Draw one with your finger, or pick a signature you’ve saved before — saved ones are reusable, so you only draw it once.
Drag it onto the first signature line and size it with the corner handles. (If it lands twice the size of the line, resizing a signature on a PDF on iPhone is a two-second fix.)
Scroll to the next page that needs it, tap + → Signature again, and pick the same saved signature. Repeat for each page.
Tap Done, then share the file back.

Where Markup is enough: two or three signature spots on a document you’re signing once. It’s free, it’s already on your phone, and if that’s your situation you genuinely don’t need an app for it.

The thing to check before you send it

This is the part that catches people out. On some iOS versions, placing signatures across several pages of one PDF and tapping Done saves the first one and silently drops the rest. No warning, no error — the file just goes back with one signature on it and blanks where the others were.

It’s the same underlying issue behind a lot of iPhone signing complaints: Markup signatures live in the PDF’s annotation layer, a separate editable layer sitting on top of the page, and that layer doesn’t always survive being written back. (That layer is also why a signature can vanish when the recipient prints the file — see how to flatten a signed PDF on iPhone for what flattening does and why it fixes it.)

So make this a habit, every time:

After tapping Done, reopen the file and scroll through every page. Don’t trust the editing view — check the saved file.
If signatures are missing, do them one page at a time: place a signature, tap Done, reopen, place the next, tap Done. Slower, but each save is small enough to stick.
Keep the original until the recipient confirms they got what they needed.

Option 2: a signature app (the route built for this)

If you’re placing the same signature four or five times, or you sign multi-page documents regularly, a dedicated app removes both the repetition and the annotation-layer risk:

Open the PDF in Mail, Gmail, Files or Outlook and tap Share.
Choose Signed (or save it to Files and import from there).
Create your signature once — draw it properly, type your name in a real handwriting style, or let AI generate one from your name. It’s saved to your library, so every placement after that is a tap.
Go page by page and tap it onto each signature line. Your initials and an auto-filled date are one tap each as well, wherever they’re asked for.
Tap Finish. You get a clean, flattened PDF — every signature baked into the page rather than floating above it — and you share that straight back.

Two things change with this route. The signature is identical on every page, because it’s the same saved image rather than a fresh finger-drawing each time. And because the export is flattened, there’s no separate layer to lose on save or ignore at print time — what you see when you tap Finish is what the recipient gets.

The privacy angle worth knowing: the big business e-sign services upload your document to their cloud in order to route it between parties. For a contract you received and just need to sign and return, none of that machinery applies — Signed is local-first, so the PDF never leaves your iPhone.

Signature on every page, or initials?

Worth separating, because senders ask for different things and the answer isn’t the same:

“Initial each page, sign at the end” — by far the most common pattern on leases and NDAs. That’s a different (and much smaller) mark, and it has its own walkthrough: how to add initials to every page of a PDF.
“Sign here, and here, and here” — multiple full signature blocks, usually because the document bundles several agreements or needs a signature per section. That’s this page.
Both — do the per-page initials first, then go back and place the full signatures and dates. Finishing one element at a time means less scrolling and far less chance of skipping a spot.

A few practical notes

Zoom in to place, zoom out to check. Placing at high zoom gets the signature sitting on the line; scrolling out afterwards catches the one that landed in the margin.
Do the last page last. The final signature block usually also wants a date and sometimes a printed name — knock out the repeat signatures first, then finish that block properly.
Signing more pages doesn’t make a document count for more. Page-by-page signing is a convention some counterparties ask for — a way of showing you read each page — not a property that changes what a document is worth. Placing a signature image on a PDF is a normal way to complete everyday paperwork, but it isn’t legal advice; if the document is high-stakes, check what that specific document actually requires.

Which should you pick?

Two or three signature spots, one time → Markup. Free, fine — just scroll through the saved file before you send it.
Several spots, a long document, or you sign these regularly → an app, for the consistent signature and the flattened export you don’t have to think about.
