This makes your phone not just a scanner, but also a smart text reader.

4. Tips for Perfect Scans Using Your Phone

To get professional-quality scans, follow these simple tips:

1. Use Good Lighting

Place the document under bright, even lighting.
Avoid shadows and reflections.

2. Lay the Document on a Dark Background

This helps the scanner detect edges clearly.

3. Hold Your Phone Steady

Keep your hands steady or place the phone on a stand for ultra-clear scans.

4. Clean the Camera Lens

Dust or fingerprints can reduce clarity.

5. Use Auto-Capture Mode

Most scanner apps automatically take the photo when aligned correctly.

6. Apply Filters Wisely

Use “Document,” “Black & White,” or “Clear” mode for crisp results.

5. Create Multi-Page PDFs on Your Phone

If you need to scan several pages:

On Android (Google Drive):

• Tap Scan

• Tap “Add page” after each scan

• Save as a single PDF

On iPhone (Notes App):

• Keep scanning multiple pages

• Tap “Save”

• iPhone auto-combines all pages into one PDF

Scanner apps like Adobe Scan and Lens also support multi-page scanning.

6. Store and Share Scanned Documents Easily

Your phone makes storing and sharing files very easy:

Save To:

• Google Drive

• OneDrive

• iCloud

• Dropbox

• Local storage

Share As:

• PDF

• Image file (JPG/PNG)

• Text file (OCR)

This is faster than using a traditional scanner or computer.

7. Best Uses of Mobile Scanning

Turning your phone into a scanner is perfect for:

• Office documents

• ID cards and certificates

• Receipts and bills

• Contracts and forms

• School notes

• Handwritten pages
