How to Scan a Document on iPhone (Notes, Files, and What to Do Next)

Quick answer: Your iPhone has a document scanner built in, no app to install. In Notes, open a note, tap the attachment button and tap Scan Documents; hold the phone over the page and it captures automatically once it detects the page edges. The same scanner lives in the Files app under the More button. Either way you get a multi-page PDF, not a photo, which is what matters when someone asks you to "scan and send" a form. If you need the text out of that PDF afterwards, or need to shrink it for an upload limit, a browser can do both without uploading anything anywhere.

Scanning in Notes (the one most people use)

Apple's official steps:

1. Open the Notes app and open a note, or start a new one.
2. Tap the attachment button, then tap Scan Documents.
3. Position the iPhone so the page fills the screen. Adjust Flash or Filters if you need to.
4. Hold steady. The iPhone captures automatically when it detects the page boundaries.
5. Scan the remaining pages, then tap Save.

The result is saved as a PDF inside the note. Tap it, then use the share button to mail it, message it, or save it to Files.

The auto-capture is the part worth trusting. Hovering and waiting a beat produces a straighter, better-cropped scan than tapping the shutter yourself, because the phone waits until it has locked onto all four corners.

Scanning in Files (better when it is going somewhere else)

If the document is destined for a folder, iCloud Drive, or an upload rather than a note, start in Files instead and skip a step later:

1. Open Files and navigate to the folder you want the scan in.
2. Tap the More button, then tap Scan Documents.
3. Place the document in view of the camera. In iOS 26 you can also pick flash or an image filter here.
4. In Auto mode it scans on its own. To capture manually, tap the Shutter button or press one of the Volume buttons.
5. Save, and the PDF lands directly in that folder.

The volume-button shutter is genuinely useful for thick or curled documents, where you are holding the page flat with one hand and cannot reach the on-screen button.

Getting a better scan

The scanner is good; the lighting usually is not. Three things fix almost every bad scan:

• Kill the shadow. The most common problem is your own head and phone shadowing the page. Put the page near a window with light coming from the side, not from behind you.
• Use a contrasting surface. A white form on a white table gives the edge detection nothing to lock onto. Put white paper on a dark table and the auto-capture fires instantly.
• Pick the right filter. The default colour filter keeps stamps and signatures readable. Black and white produces much smaller files and crisper text for plain printed forms, which matters if there is an upload size limit at the other end.

If a corner comes out wrong, you do not have to rescan: tap the scan, then drag the corner handles to re-crop before saving.

What to do with the scan afterwards

This is where people get stuck, because the iPhone gives you a PDF and the task usually needs something else.

"I need the text, not a picture of the text." A scanned PDF is images of pages; you cannot select or search the words. Run it through a PDF to text extractor: it reads the text layer if there is one, and OCRs the pages if there is not, in 24 languages. Everything runs in your browser, which matters when the document is a contract or a medical form.

"The upload says the file is too large." Scanner PDFs get big fast, especially in colour at several pages. Rescanning in the black and white filter is the first fix. If it is still too large, compress the PDF or convert its pages to images and shrink those.

"They want photos, not a PDF." Some portals reject PDFs. Turn the pages back into images with PDF to JPG.

"I already took photos instead of scanning." If you photographed the pages rather than scanning them, you do not need to start over. Combine the images into a single PDF in page order, which is what the recipient wanted in the first place. To pull the words out of a single photographed page, use image to text.

Scan versus photo: why it matters

Taking a photo of a document and scanning it are not the same thing, and the difference shows up at the other end:

	Photo	Scan
Output	JPG or HEIC image	Multi-page PDF
Perspective	Whatever angle you held the phone at	Flattened to a rectangle
Cropping	The whole table, your hand, the floor	Just the page
Multiple pages	Separate files	One document
Metadata	Carries capture date, and often GPS	Page images in a PDF wrapper

That last row is worth pausing on. A photo of a document carries EXIF metadata including, in most default iPhone setups, the GPS coordinates of where you took it. If you photograph a lease or a payslip at home and email the image, you may be sending your home address along with it. You can check what a given photo reveals with the EXIF viewer, and strip it with the EXIF remover. Scanning avoids the issue, which is one more reason to use the scanner rather than the camera for paperwork.

Frequently asked

Does the iPhone scanner work without an internet connection? Yes. Scanning, cropping and PDF creation all happen on the device.

Can I sign the scan? Yes. Open the PDF, tap the Markup button, then add a signature. This is what most "please sign and return" requests actually need.

Where do Notes scans get saved? Inside the note itself. Use the share button to export the PDF to Files, Mail, or anywhere else. Starting the scan in Files instead saves you that step.

Can I scan on an iPad? Same feature, same steps, in both Notes and Files.

Is there a page limit? No practical limit, though very long colour scans produce large files. Use the black and white filter for anything over a few pages.

Bottom line

The iPhone scanner is in Notes (attachment button → Scan Documents) and in Files (More → Scan Documents), it auto-captures when it sees the page edges, and it hands you a proper multi-page PDF. Use a side-lit page on a contrasting surface and the scans come out straight the first time.

Everything after the scan (pulling the text out, shrinking the file, converting pages to images) can happen in a browser tab without the document ever leaving your device. Start with PDF to text if you need the words, or image to PDF if you photographed the pages instead of scanning them.
