How to Get the Best Scans from Your iPhone

Regardless of which best free scanner app for iPhone you choose, follow these tips for optimal results:

Pro tips:

• Scan near windows during daytime
• Use overhead lighting to eliminate shadows
• Avoid direct sunlight that creates glare
• Turn on all room lights for indoor scanning

2. Use a Clean Surface

Place your document on a clean, clutter-free surface and remove any dirt, dust, or debris affecting scan quality.

Best practices:

• Use solid-colored backgrounds (white, black, or neutral)
• Ensure documents lie completely flat
• Remove any objects from the frame
• Clean your iPhone camera lens

3. Hold Your iPhone Steady

Hold your iPhone steady while capturing the image to prevent blurriness—use a tripod or stable surface to maintain consistent angle if possible.

Stability techniques:

• Use both hands to hold your iPhone
• Rest your elbows on a table for support
• Take a deep breath and hold it while scanning
• Consider a phone tripod for multiple scans

4. Optimal Distance and Angle

• Hold your iPhone directly above the document (perpendicular)
• Maintain 8-12 inches distance from the document
• Ensure the entire document fits within the frame
• Let the app’s edge detection work its magic

5. Post-Scan Enhancements

• Use the app’s filters to improve readability
• Crop out any unnecessary edges
