How to add an electronic signature in Apple Notes on iPhone
What you actually have is a PDF attached to a note, or a document you scanned into one. Here is how it gets signed and sent back, on the phone in your hand — no printer, no scanner, no account.
Option A · free · nothing to install
Apple Notes’ own scanner and Markup — free, already installed
Notes scans a paper form with the camera and marks it up in the same app, at no cost. For a single form that is the whole job.
- Open what you have in Apple Notes. What you are dealing with is a PDF attached to a note, or a document you scanned into one.
- Get it to a screen that can sign. Tap the attachment to open it, then use the Markup icon — Notes can also scan a paper form straight into a note with Scan Documents.
- Sign it. Tap the + at the bottom right of Markup, choose Signature, sign with your fingertip, tap Done, then drag the signature onto the line and pull the blue handles until it sits on the line rather than through the text underneath.
- Send it back. Share the signed copy from the note using the share icon.
If this is a one-off, stop here. The free route above signs the document and sends it back. Where it gets slow is repetition: Apple Markup holds one signature and no initials, text boxes do not snap to the form’s lines, there is no date shortcut, and nothing you place is flattened into the page.
Option B · with Signed
Sign it with Signed instead
Same document, fewer taps — because the signature, the initials and the date are already saved, and everything you place is flattened into the exported PDF.
- Share the PDF into Signed. From the same share sheet you reached out of Apple Notes, pick Signed — or import the PDF from inside the app. It stays on your iPhone: nothing is uploaded and there is no cloud copy.
- Drop in the signature you already saved. Tap the signature line and place the signature you made once — drawn with a fingertip, typed in a real handwriting style, or generated with AI. You never redraw it per document.
- Fill in the rest of the page. Add the date, your initials, your name, text and checkmarks with the matching tools. Today’s date fills itself in and saved initials are one tap per page.
- Export a flattened PDF and send that. Export the signed copy flattened, so the signature and every field become part of the page rather than a layer someone can drag off it. Then share the signed copy from the note using the share icon.
The catch with Apple Notes
Notes can scan and it can mark up, which covers a lot of ground for free. What it cannot do is keep a reusable signature — you redraw it every time, which is fine once and tedious weekly.
Signed signs PDFs. It does not convert file formats, sync your files, or send documents out for someone else’s signature — which is why anything that is not already a PDF goes through Apple Notes’s own export first.

Signed is a signing tool, not legal advice. Whether an electronically signed copy is accepted depends on the document, the counterparty and where you are — for anything high-stakes, check what your jurisdiction requires, including whether a notary or witnesses are needed.
