You can scan documents with an Android phone using Google Drive or Files by Google. Drive is convenient when you want the file in your Google account; Files by Google is useful when you want a PDF saved on the phone.
A document scan differs from an ordinary photograph: the app can straighten the page, crop the background, and combine several pages into one file. You still need to check the result before submitting it.
Prepare the page before opening the scanner
Place the document flat on a surface that contrasts with the paper. Use even light and avoid glare, particularly on glossy receipts or laminated cards. Hold the phone above the page with the camera roughly parallel to it.
Wipe the camera lens with a suitable soft cloth if text looks hazy. Moving closer is usually better than relying on heavy digital zoom, provided the entire page still fits in view.
For a multi-page document, arrange the pages in order first. Check whether the recipient requires a PDF, separate images, a color scan, or a maximum file size. That determines what to export.
Scan into Google Drive
These steps follow Google’s current Android document scanning instructions. Button labels can differ slightly with app updates.
- Open Google Drive and confirm the account in the profile menu.
- Tap the Camera button. If your version presents an add menu, choose Scan.
- Allow camera access if requested, then frame the page.
- Capture it automatically or use manual capture.
- Review the preview. Adjust Crop and rotate or the filter if necessary.
- For another page, tap Add and repeat the capture.
- Tap Done, give the document a recognizable name, and choose PDF for a combined document or JPG where available for an image.
- Select the destination folder and tap Save.
Open the saved file and inspect it. If you need it on another device, wait for the upload to finish and confirm that you can open it from that account. Saving into Drive does not make the file public, but later sharing settings can expose it.
Use a descriptive name such as rental-agreement-signed.pdf instead of leaving several files with indistinguishable scan titles.
Prefer a PDF stored on the phone? Use Files by Google
Files by Google is a particular app; it is not necessarily the same as the manufacturer’s app called Files or My Files. Update it if the scanning option is missing.
Open Files by Google, tap Scan, and capture the page. Use the preview controls to correct the crop, rotate it, or add another page. Tap Done when the document is complete.
According to Google’s Files scanning guide, scans are saved as PDFs in the Scanned folder within Downloads. Look under Recents, use the Documents category, or search for the filename.
The saved PDF is not automatically backed up to Drive merely because both apps are made by Google. Share or upload it separately if you need an additional copy. For another phone, see how to transfer data from Android to Android.
Check the scan at reading size
Zoom in on small print, dates, signatures, and reference numbers. A page that looks sharp as a thumbnail can still contain blurred text. Retake a blurred page rather than trying to hide the problem with a stronger contrast filter.
Check all four edges. Automatic cropping sometimes removes a handwritten note or a signature near the margin. For multiple pages, confirm the page count and order before sending the file.
Searchable text is helpful, but optical character recognition can misread handwriting, faded receipts, and unusual fonts. Verify important amounts and names against the visible page. A searchable PDF is not necessarily an editable word-processing document.
When the attachment is too large
Use a PDF for a multi-page document and avoid unnecessarily high-resolution duplicate images. If compression is needed, work on a copy and check that the smallest text remains readable afterward.
For private records, choose an approved offline tool or service rather than uploading the file to an unfamiliar compression website. Keep the readable original until the recipient confirms the file was accepted.
Fix capture or saving problems
If the scanner shows a black camera view, check the app’s camera permission in Settings > Apps > [app name] > Permissions. Close other camera apps and reopen the scanner.
If the file will not save, check available phone storage. Use safer ways to free up Android storage before deleting documents you still need. For Drive, also check connectivity and available account storage.
A screenshot is appropriate for information already on the display, not a paper document. If that is what you need, use how to take a screenshot on Android instead. Before sharing either kind of file, remove unnecessary personal information and check the actual attachment you are sending.
