Why Text Looks Blurry in a Photo PDF and How to Fix It

Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points
  • Causes are shooting (focus, shake, darkness) or too much compression
  • Retaking is the most effective; quality settings can also help
  • Use a size limit only as small as you need

Text in your PDF looks blurry. There are two main causes: a problem when shooting, or too much shrinking.

Cause 1: shooting

Cause 2: too much compression

Choosing "Small file" quality or a small size limit makes the file smaller but the text rougher.

What to do, in order

  1. First zoom in on the original photo and check whether the text is readable.
  2. If it is blurry, retake it.
  3. If the photo is sharp, rebuild the PDF with higher quality.
When there is a size limit, put readability first and use the largest size the limit allows.
