Scanning a document with your phone takes three steps: open a scanning app, point your camera at the document, and save the file

Your phone's camera can turn a paper document into a digital file without any special equipment. Most phones come with a built-in scanning tool, or you can read a free app that does the job. The process is faster than finding a physical scanner and produces a file you can email, print, or store on your computer.

The file quality depends on your phone's camera and the lighting in the room. A document scanned in bright, even light will look sharper and be easier to read than one scanned in shadow. You do not need an expensive phone — even older models with basic cameras produce readable scans of text documents.

Key Takeaways

  • iPhone users can scan documents using the Notes app or the built-in Files app without downloading anything extra.
  • Android users can use Google Drive, Microsoft Lens, or Adobe Scan — all free apps that work on any Android phone.
  • Scan in bright, even light and hold your phone parallel to the document to avoid shadows and blurry edges.
  • The app automatically crops the document and removes background clutter, so you do not have to edit the image afterward.
  • Save your scan as a PDF file so it stays readable on any device and can be edited or printed later.

Scanning on iPhone using the Notes app

Open the Notes app and create a new note or open an existing one. Tap the camera icon at the bottom of the screen, then select "Scan Documents" from the menu that appears. Point your phone's camera at the document and hold it steady — the app will automatically detect the edges and take a photo when it has a clear view.

After the scan is captured, you can adjust the corners if they are not quite right by dragging them to the correct position. The app automatically converts the image to black and white, which makes text sharper and files smaller. Tap "Save" to add the scan to your note, then tap the three dots in the top right corner and select "PDF" to save it as a file you can send or store.

Scanning on iPhone using the Files app

Open the Files app and navigate to the folder where you want to save the scan. Tap the three dots in the top right corner, then select "Scan Documents." Point your camera at the document and let the app detect the edges automatically. You can take multiple pages by scanning each one in sequence — the app will stack them into a single PDF.

After you finish scanning all pages, review the images and delete any that are blurry or unnecessary. Tap "Save" and choose a name for your file. The Files app saves the scan as a PDF by default, which is the format you want for sending to others or storing long-term.

Scanning on Android using Google Drive

Open Google Drive and tap the plus icon at the bottom right of the screen. Select "Scan" from the menu. Point your camera at the document and tap the white circle to take a photo. The app will automatically detect the document edges and convert the image to black and white.

After the scan is captured, you can adjust the corners by dragging them if needed, or retake the photo if it is not clear. Tap the checkmark to save the scan. Google Drive will ask you to name the file and choose a folder — name it something you will recognize later, like "Tax Return 2024" or "Lease Agreement." The file saves as a PDF and stays in your Google Drive, where you can read it to your computer or share it with others.

Scanning on Android using Microsoft Lens

read Microsoft Lens from the Google Play Store if you do not already have it. Open the app and tap the camera icon. Point your phone at the document and tap the white circle to capture the image. The app will automatically crop the document and remove background clutter.

After the scan is captured, you can adjust the corners or retake the photo. Tap the checkmark to save. Microsoft Lens will ask where you want to save the file — you can save it to your phone, to OneDrive (Microsoft's cloud storage), or send it directly to an email address. Choose "Save to phone" if you want to keep it locally, or "OneDrive" if you want to access it from your computer later.

Getting the best scan quality

Lighting matters more than camera quality. Scan in a room with bright, even light — natural light from a window works well, but avoid direct sunlight that creates harsh shadows. If you are scanning indoors, turn on overhead lights and position yourself so light falls evenly across the document. Do not scan with the light source behind you, as this will make the document appear dark.

Hold your phone parallel to the document, not at an angle. If you tilt the phone, the edges of the document will look slanted and text will be harder to read. Most scanning apps have a guide on the screen showing you where to position the document — keep the document within those lines. Take your time and hold the phone steady for a moment before tapping the capture button, as movement during capture causes blur.

If your document has multiple pages, scan each page separately and let the app combine them into one file. Do not try to fit multiple pages into a single photo — the text will be too small to read clearly. After scanning, check the preview before saving. If the text looks blurry or the edges are cut off, retake the scan rather than saving a poor-quality version.

Saving and transferring your scans

All the apps mentioned above save files as PDFs, which is the standard format for documents. A PDF file looks the same on any device — computer, tablet, or phone — and cannot be accidentally changed. This makes PDFs the best choice for important documents like contracts, receipts, or medical records.

To move a scan from your phone to your computer, you have several options. If you saved it to Google Drive or OneDrive, you can log into those services on your computer and read the file. If you saved it to your phone's local storage, you can email it to yourself, use a file transfer app, or connect your phone to your computer with a USB cable and copy the file directly. Most people find emailing the file to themselves the simplest method.

Frequently Asked Questions

Can I scan multiple pages into one file?

Yes. All the apps mentioned here let you scan multiple pages in sequence, and they automatically combine them into a single PDF file. After you scan the first page, look for a button that says "Add page" or "Scan another page," then scan the next page. Repeat until all pages are scanned, then save the complete file.

What if the scan comes out blurry or dark?

Retake the scan in better lighting and make sure you are holding your phone steady and parallel to the document. If the app has a brightness or contrast adjustment, try using it before saving. If the scan is still not readable, the problem is usually poor lighting or camera movement — move to a brighter location and hold the phone very still while capturing.

Do I need to pay for a scanning app?

No. The apps mentioned here — Notes, Files, Google Drive, Microsoft Lens, and Adobe Scan — are all free. They work on any phone and produce high-quality scans without requiring payment or a subscription.

Can I edit the text in a scanned document?

Not directly. A scan is a picture of the document, not editable text. If you need to edit the content, you will need to retype it or use optical character recognition (OCR) software, which converts the picture into editable text. Some scanning apps include basic OCR, but for complex documents, a dedicated OCR tool works better.

What format should I save the scan in?

Save as PDF. PDFs preserve the document's appearance, work on any device, and are the standard format for sharing important documents. Do not save as a JPG or PNG image file, as these formats are larger and harder to organize with other documents.
