Use the Built-In Notes App or Files App to Scan Without Extra Software

Your iPhone has a document scanner built in. You do not need to read anything. Open the Notes app, tap the camera icon at the bottom of the compose window, then tap "Scan Documents." Position your phone over the document, and your iPhone will automatically detect the edges and capture the page. You can scan multiple pages in one session — each one adds to the same document. When you are done, tap "Save" and choose where to store it.

If you prefer to use the Files app instead, open it, navigate to a folder where you want to save the scan, tap the three dots in the bottom right, select "Scan Documents," and follow the same process. Both methods save your scan as a PDF, which you can then open in any document editor or email to someone else.

The scanner automatically crops the document, removes shadows, and adjusts the color so text is readable. If the automatic settings do not look right, tap "Retake" and try again from a different angle or distance.

Key Takeaways

  • The Notes app and Files app both have built-in document scanners — you do not need to install a separate app.
  • Scans save as PDFs that work with any document editor or email program.
  • Your iPhone automatically detects document edges, removes shadows, and adjusts color for readability.
  • You can scan multiple pages in one session and edit or delete individual pages before saving.
  • Scans are stored on your phone by default, but you can move them to cloud storage like iCloud Drive or Google Drive after scanning.

How to Adjust Scan Quality and Color Settings

After you capture a page, the scan appears on your screen with adjustment options. Tap the thumbnail of the scan to open it. At the bottom, you will see buttons to change the filter — options include "Original," "Grayscale," "Black and White," and "Color." Tap each one to see how it changes the appearance. "Black and White" makes text sharper and files smaller, which is useful if you are scanning printed documents. "Color" preserves any colored text or images.

If the automatic crop cut off part of your document, tap "Crop" and drag the corners to include the full page. If the page is tilted, tap "Rotate" to straighten it. These edits only affect the saved file, not the original document.

Before you save, review all the pages you scanned. Swipe left or right to move between them. If one page is blurry or captured at a bad angle, tap the trash icon to delete it and retake that page.

Save Your Scans to the Right Place for Your Workflow

When you tap "Save" in Notes or Files, your scan goes into that app by default. If you scanned in Notes, the PDF appears as an attachment in that note. If you scanned in Files, it saves to the folder you selected. From either location, you can move it later.

To save a scan directly to cloud storage, open Files after scanning, navigate to iCloud Drive or Google Drive, create a new folder if you want to organize by project or date, and move the PDF there. This keeps your scans backed up and accessible from your computer or other devices. If you use a document editor like Google Docs or Microsoft Word, you can also open the PDF in that app and save it to your account.

Consider creating a folder structure before you start scanning — for example, "Medical Records 2024" or "Home Repairs" — so you can find scans later without searching through dozens of files.

Email or Share a Scan Directly From Your iPhone

After you save a scan, you do not have to navigate back to find it to share it. In Notes, open the note containing the scan, tap and hold the PDF thumbnail, and select "Share." In Files, tap and hold the PDF and select "Share." A menu appears with options to send via Mail, Messages, AirDrop, or any other app you have installed.

If you are sending to someone outside your contacts, Mail is usually the fastest option. The PDF attaches automatically. If you are sharing with someone on the same Wi-Fi network, AirDrop is faster and does not use email. Messages works if you want to send to a specific person and have a text conversation about it at the same time.

Organize Multiple Scans Into One Document

If you scanned several pages and want to combine them into a single PDF before sharing, the easiest method is to scan all pages in one session. When you finish, all pages are already in one file. Tap "Save" and give it a name like "Tax Return 2024" or "Lease Agreement."

If you scanned pages at different times and want to merge them, you will need a document editor. Open Google Docs, create a new document, and insert each PDF as an image. This is slower than scanning in one session, but it works if you have already saved the individual scans. Alternatively, some PDF apps like Adobe Acrobat Reader (free version) let you combine PDFs, though the free version has limits on how many files you can merge at once.

Troubleshoot Common Scanning Problems

If your iPhone does not recognize the document edges, make sure the document is flat and well-lit. Shadows from your hand or phone can confuse the scanner. Try moving to a brighter area or adjusting the angle. If the text is still blurry after you save, the original photo was out of focus — delete it and retake the scan, holding your phone steadier and waiting for the camera to focus before capturing.

If the scan is too dark or too light, the automatic exposure adjustment did not work well. Retake the scan and try a different distance or angle. If you are scanning a glossy document, angle your phone slightly to reduce glare. If the file is too large to email, use the "Black and White" filter to reduce the file size, or upload it to cloud storage and send a link instead.

If you cannot find the scan after saving, check the Notes app or Files app where you saved it. Scans do not appear in the Photos app unless you explicitly save them there. If you saved to iCloud Drive, make sure you are signed into iCloud on your iPhone — go to Settings, tap your name, and check that iCloud Drive is turned on.

Frequently Asked Questions

Can I scan a document without the Notes or Files app?

The Notes and Files apps are the only built-in scanners on iPhone. Third-party apps like Adobe Scan, Microsoft Lens, or Evernote also have document scanners, but they require downloading and often ask for an account. The built-in option is faster if you just need a quick scan.

What format does my iPhone scan save as?

Scans save as PDF files. PDFs work with any document editor, email program, or web browser. You can also convert a PDF to another format like Word or image files using a document editor or online converter, though the built-in PDF format is usually the best choice for sharing and storing.

Can I edit the text in a scanned document?

Not directly from the scan itself. If you need to edit text, you can open the PDF in a document editor like Google Docs or Microsoft Word, which have optical character recognition (OCR) that converts the scanned image into editable text. This works best with clear, printed text and may have errors with handwriting or unusual fonts.

How much storage does a scanned document use?

A single page scan typically uses 500 KB to 2 MB, depending on the filter you choose. "Black and White" uses less space than "Color." A 10-page document might use 5 to 20 MB. If storage is tight, move scans to cloud storage like iCloud Drive or Google Drive to free up space on your phone.

Can I scan a document that is larger than my phone screen?

Yes. Position your phone over one section, capture it, then move to the next section and capture again. Each section becomes a separate page in the same scan. This works for large posters, blueprints, or multi-page documents you want to keep as one file. Just make sure there is some overlap between sections so you can see where they connect.
