What You Need Before Scanning Documents on iPhone
Before scanning, set yourself up for the best results. A tiny bit of prep makes a huge difference in quality.
- An iPhone running a recent version of Apple’s iOS.
- Good lighting (natural light is best).
- A flat surface to place your document.
- A clean camera lens (wipe it with a soft cloth).
That’s it. Whether it’s a last-minute form, an important receipt, a signed contract, or school notes, you can scan, edit, and send everything straight from your phone.
Method 1: Scan Documents on iPhone Using the Notes App
The Notes app on your iPhone is one of the easiest ways to scan documents and it’s completely free. You don’t need to install anything or create an account. The scanner is built right in and automatically turns your paper into a neat, cropped PDF.
- Open the Notes app.
- Open an existing note or create a new one by tapping the pen icon.
- Tap the attachment icon above the keyboard.
- Choose Scan Documents from the options.
- Place your document on a flat surface and hold your iPhone over it. The app will auto-detect the edges.
- You can turn on flash or apply filters like Grayscale, Black & White, etc.
- It automatically captures the scan if Auto Shutter is enabled. Or you can press the shutter button to capture the document and crop it to your preference.
- Tap Keep at the top right corner to repeat for more pages. If you don’t like the scan, tap Retake.
- Finally, tap the checkmark to save the scans.
Your scan is now stored inside the note as a PDF. Now, you can tap the down arrow next to Scanned Documents and rename the PDF, send it via Mail, Messages, AirDrop, print it, or save it to Files.
Method 2: Scan Documents on iPhone Using the Files App
If you want the scanned file saved directly as a PDF in storage (instead of inside a note), use the Files app.
- Open the Files app and move to the Browse tab.
- Choose On My iPhone or iCloud Drive under Locations.
- Tap the three dots in the top-right corner.
- Choose Scan Documents.
- Position the document in your camera view and tap the shutter button just like in Notes.
- Repeat scanning more pages and tap the checkmark button to save it.
- Name the file and choose where to store it.
Now you have a proper PDF file ready to upload anywhere.
How to Edit Scanned Documents on iPhone
After scanning, you’re not stuck with the first result. The iPhone gives you built-in editing tools. I’ll show you the steps using a scanned document in the Notes app.
- Open the note with the PDF.
- Tap the square icon next to the document name. It will show you all the scanned pages in the PDF.
- Now, tap the three-dot icon on the page you want to edit.
- Rotate: Turn the page left or right.
- Crop Page: It will display the original page with cropping handles. Once done, tap the checkmark.
- Apply different filters: Switch between color, grayscale, black & white, or photo mode.
- Add more pages to an existing scan: You can insert a blank page, a document from Files, or scan new pages.
- Delete Page: Remove that specific page.
All changes update instantly and can be undone. So, don’t worry about accidental deletion.
