You don’t need a scanner to send clear copies of documents. With good photos and the right tool, your phone can produce PDFs that look like they came from an office scanner.

Step 1: Take good photos

  • Place the page on a dark, flat surface so its edges stand out.
  • Use daylight or a bright room; turn off the flash to avoid glare.
  • Hold the phone directly above the page, parallel to it.
  • Fill the frame with the page and keep the phone steady.

Step 2: Turn the photos into a scanned PDF

  1. Open Scan Images to PDF.
  2. Add your photos in order.
  3. The tool removes shadows and grey paper tones, leaving sharp black text on white.
  4. Download the PDF.

Step 3: Final touches

When to keep colour

Black-and-white is perfect for text documents. For photos, coloured stamps or ID cards where colour matters, use JPG to PDF instead.
