The basic steps for scanning with your phone
Most phones can scan documents using either a built-in app or a free app from your device's store. On iPhones, open Notes, tap the camera icon, and select "Scan Documents" — the phone will detect the document edges automatically and save it as a PDF. On Android phones, Google Drive has a built-in scanner: open the app, tap the plus sign, select "Scan", and point your camera at the document.
The process takes about 30 seconds per page. Your phone will show you a preview of what it captured, let you adjust the corners if the edges aren't quite right, and then save the file to your phone's storage or cloud account. You can scan multiple pages in one session and combine them into a single file.
Key Takeaways
- iPhone users can scan documents directly in the Notes app without downloading anything extra.
- Android users can scan through Google Drive, which is free and comes pre-installed on most phones.
- Both methods automatically detect document edges and convert the image to a PDF file.
- You can scan multiple pages and save them as one file, then share or email the result immediately.
Scanning on iPhone using Notes
Open the Notes app and create a new note or open an existing one. Tap the camera icon at the bottom of the keyboard, then tap "Scan Documents" from the menu that appears. Point your phone's camera at the document — you don't need to hold it perfectly still. The phone will automatically detect the document's edges and capture it when it's in focus.
After the scan, you'll see a preview with the document corners highlighted. If the corners aren't quite right, drag them to the correct position. Tap "Keep Scan" to save it. To scan another page, tap the camera icon again and repeat. When you're done, the scans stay in that note as a PDF that you can share, email, or print directly from Notes.
Scanning on Android using Google Drive
Open Google Drive and tap the plus sign button in the bottom right corner. Select "Scan" from the menu. Point your camera at the document — the app will automatically capture it when it detects the edges are in frame and the lighting is clear enough. You'll see a preview of what was captured.
If the scan looks good, tap the checkmark to save it. If you need to adjust the corners, tap the crop icon and drag the corners to the right position. To add more pages to the same file, tap the plus sign again and scan the next page. When finished, the file saves automatically to your Google Drive as a PDF and you can rename it, share it, or download it to your phone.
Getting the clearest scans
Lighting matters more than camera quality. Scan in natural light or under a lamp — avoid shadows falling across the document. Hold your phone 6 to 12 inches above the page and keep it as level as possible. The document doesn't need to fill the entire screen; the app will detect and crop the edges automatically.
If the first scan comes out blurry or dark, try moving closer to a light source or tilting your phone slightly. Both iPhone Notes and Google Drive will let you retake a scan if the first attempt isn't clear. Dark or colored paper scans less clearly than white paper, so if you're scanning something important, use white paper if possible.
Where your scans are saved
On iPhone, scans in Notes stay in that specific note. To find them later, open Notes and search for the note by name. You can also export the PDF by tapping the three dots in the note, selecting "Collaborate", and choosing "Copy Link" to share it, or tap the share icon to email it or save it to another app.
On Android, scans go directly to your Google Drive in a folder called "My Drive" unless you choose a different folder. You can access them from any device by logging into Google Drive online, and you can download them to your phone, email them, or share a link. Both systems keep the files on your phone and in the cloud, so you won't lose them if your phone is damaged.
Alternatives if your phone doesn't have a scanner
If your phone is older or doesn't have a built-in scanner, download a free scanning app like Adobe Scan, Microsoft Lens, or Camscanner from your phone's app store. These apps work the same way — point at a document, let the app detect the edges, and save as a PDF. Adobe Scan and Microsoft Lens are free with no ads or paywalls for basic scanning.
Some of these apps offer extra features like automatic text recognition (reading the words in the document so you can search them later) or cloud storage, but you don't need those features for a basic scan. Start with the app that comes with your phone first — if it doesn't work well, try one of these alternatives.
Frequently Asked Questions
Can I scan a document that's not on white paper?
Yes, but the results may be less clear. Colored or dark paper, receipts, and photographs all scan, but they may come out darker or with less contrast. If the text is hard to read after scanning, try adjusting the lighting or moving closer to a light source and rescanning.
What if my scan comes out crooked or has shadows?
Both iPhone Notes and Google Drive let you adjust the corners after scanning. If shadows are the problem, rescan in better lighting. If the document is crooked in the preview, drag the corners to straighten it before saving.
Can I scan multiple pages into one file?
Yes. In iPhone Notes, scan the first page, then tap the camera icon again and scan the next page in the same note — they'll combine into one PDF. In Google Drive, scan the first page, tap the plus sign, and scan additional pages to the same file.
How do I email a scanned document?
On iPhone, open the note containing the scan, tap the share icon, and select Mail. On Android, open Google Drive, find the scanned file, tap the three dots, and select "Share" or "Send". Both will let you email it directly or copy a shareable link.
Do I need an internet connection to scan?
No. iPhone Notes and Google Drive both work offline — the scan saves to your phone first. Google Drive will sync to the cloud when you reconnect to WiFi or mobile data, but the file is safe on your phone either way.
