GOOD TO KNOW
A few habits make phone scans as readable as a flatbed scanner.
| TIP | WHY | THEN |
|---|---|---|
| Use daylight or a bright lamp | Shadows make text harder to read | Keep your own shadow off the page |
| Lay the page flat on a dark surface | Edges are easier to find and crop | The app finds them automatically |
| Hold the phone straight above | Tilted photos make lines slant | Crop and straighten afterwards |
| Run OCR afterwards | Scans are pictures until text is added | OCR PDF makes them searchable |
Use even lighting and keep the camera parallel to the page. Review every page before saving.
