A paper document needs to become a PDF and you have an iPhone in your pocket — that is a complete workflow by itself. iPhone can scan documents to PDF for free in two ways: the scanner built into the Notes app, and a browser-based scanner with auto-detection that runs entirely on the device.

Here is how to scan a document to PDF on your iPhone, both ways.

Scan with the built-in Notes app

Every iPhone ships with a document scanner hidden inside Notes. It needs no download and produces a PDF you can share anywhere:

  1. 1Open Notes and start a new note (or reuse an existing one).
  2. 2Tap the camera icon in the toolbar, then tap Scan Documents.
  3. 3Hold the iPhone over the page — the yellow auto-detector frames it and captures when it focuses.
  4. 4Keep scanning pages; each is added to the same document.
  5. 5Tap Save, then tap the document thumbnail and choose Export as PDF (or long-press it and pick Share).
  6. 6Share to Files for a permanent copy, or AirDrop/email the PDF.

The Notes scanner is quick and automatic, and it is the best zero-setup option for a document staying inside Apple’s ecosystem.

Scan in Safari with auto page detection

For more control — filters, rotation before saving, and a review step before each page is locked in — a browser-based scanner runs in Safari:

  1. 1Open the Scan PDF tool in Safari on your iPhone.
  2. 2Tap Open camera and allow camera access when prompted.
  3. 3Centre the page in the frame and hold steady while the detector outlines it.
  4. 4The outline turns green when stable and captures automatically, or tap the shutter for a manual shot.
  5. 5On the adjust screen, rotate or apply a filter, then tap Save; keep going for more pages.
  6. 6Tap Done and download the finished PDF to Files.

Make the result smaller if needed

A scan of a dense page can land at a few megabytes, which is over some email limits. Compress the finished PDF in your browser afterwards to bring it under the limit without visibly hurting text.

Frequently asked questions

How do I scan a document to PDF with an iPhone for free?+

Open the Notes app, tap the camera icon, and choose Scan Documents. Scan the pages, then use Share to save the document as a PDF. Safari-based scanners do the same with more control.

Where does the Notes scanner save scans?+

Inside the note you scanned them into. Export the document with Share to save it as a standalone PDF in Files, or send it directly.

Can I scan multiple pages into one PDF on iPhone?+

Yes. Continue scanning in the Notes app and every page joins the same document; a browser-based scanner does the same and delivers one multi-page PDF.

Do I need a scanner app?+

No. The Notes app has scanning built in, and browser-based scanners run in Safari with no install.

Is my scan uploaded anywhere?+

The Notes scanner stores scans in your iCloud account. A browser-based scanner processes the document on your iPhone with no upload to a server.
