You don't need a scanner app to turn paper into a PDF on iPhone. The built-in scanner in Notes and Files creates clean, cropped PDFs that you can email, upload or save. Here's how to do it, how to get better results, and how to share and organize the PDF.
Key takeaways
- Use Scan Documents in Notes or Files. Both create PDFs.
- Files saves the PDF straight into a folder; Notes keeps it in a note until you share it.
- Tap Share to email, AirDrop, or save to iCloud Drive.
- Rename the PDF in Files so it's easy to find.
Method 1: Scan with Files
- Open Files and go to the folder where you want the PDF.
- Tap the More button (three dots), then Scan Documents.
- Capture each page (Auto mode captures automatically; Manual uses the shutter).
- Adjust corners if needed and tap Keep Scan.
- Tap Save. The PDF appears in the folder.

Notes or Files?
| If you want to... | Use |
|---|---|
| File the PDF in a folder immediately | Files |
| Keep a scan with notes or a checklist | Notes |
| Upload to a website form | Files, so it's easy to pick |
| Scan quickly and decide later | Notes |
Share the PDF
Tap Share to email, AirDrop or save to iCloud Drive. From the share sheet you can also send it via Messages, WhatsApp or another app, or print it with AirPrint.
Rename and organize
In Files, long-press to rename the PDF so it's easy to find. A consistent naming pattern, such as "2026-10-15 Insurance claim," makes searches simple. Add tags like "Tax" or "Medical" and use folders by year.
Tips for a better PDF
- Scan in bright, even light without shadows.
- Use a dark background to help edge detection.
- Choose Black & White for text documents. It's sharper and makes smaller files, which helps with upload size limits.
- Use Color for photos, receipts with color logos, or ID documents if the recipient requires color.
- Flatten folded or curled pages.
Combining and reordering pages
- While scanning: keep adding pages before you tap Save.
- After scanning: in Files, select several PDFs or images, tap the More button and choose Create PDF to merge them.
- Reordering: open the PDF in Files or Preview (iOS 26 and later) and use the page thumbnails to rearrange or delete pages, where available.
Copying text from a scan
iPhone's Live Text can recognize text in photos and many scanned documents. Open the PDF, touch and hold the text, and choose Copy if it's selectable. For long documents or editable files, a dedicated OCR app may work better. See do you need a scanner app?
File size limits
Some websites limit uploads to a few megabytes. If your PDF is too big, rescan in Black & White, scan fewer pages per file, or use a compression tool. Avoid sending sensitive documents to unknown online compressors.
Signing a PDF
To sign before sending, open the PDF in Files, tap Markup, then the plus button, then Add Signature. See how to sign a PDF on iPhone for free.
Faxing a PDF
If a recipient insists on fax, you'll need a fax service. See how to send a fax from your iPhone.
Scanning ID cards and two-sided documents
For a driver's license or insurance card, scan the front, then flip it and scan the back as the next page of the same document. Both sides end up in one PDF, which is what most forms ask for. Use Color mode for IDs, since some organizations reject black-and-white copies, and only share ID scans with organizations that genuinely need them.
Troubleshooting
- The scanner keeps capturing too early: switch from Auto to Manual so you control the shutter.
- Pages look skewed: drag the corner handles to the page edges before tapping Keep Scan.
- Text is too faint: try the Grayscale filter, or rescan in better light.
- Can't find the PDF: in Files, tap Recents or search for "Scanned Document."
