How to scan documents with your phone
Contracts, forms, certificates, school letters: a phone scanner can replace the office scanner for a lot of everyday paperwork. The difference between a scan that looks professional and a blurry, shadowed photo comes down to light, background and a couple of settings.
A step-by-step method, then document scanner apps. Some official submissions require original documents or certified copies; check before relying on a phone scan.
Set up light and background
Place the page on a dark, plain surface in soft, even light. Avoid the flash, which causes glare, and hold the phone parallel to the page so your shadow does not fall on it.
Let the app do the cropping
Scanner apps detect page edges, straighten the image and remove the background. Check the corners before saving, and scan multi-page documents into a single file.
Pick the right output
Black and white keeps text crisp and files small; use colour for IDs, photos and stamps. Turn on text recognition (OCR) where available so you can search inside the PDF later.
Name and store it
Use a clear name with date and topic, and keep scans in one organised folder with a backup. For keeping important files safe, see how to store important documents safely; compare apps in document scanner apps.
| Step | What you do | Why |
|---|---|---|
| 1. Light | even daylight, no flash glare | no shadows |
| 2. Background | dark, plain surface | clean edge detection |
| 3. Capture | let the app find the edges | straight, cropped pages |
| 4. Mode | black and white for text, colour for IDs | readable files |
| 5. Save | searchable PDF, clear name | easy to find later |
