Recommended prompts

  • Make this scanned page easier to read with minimal changes: gently brighten the paper, improve text contrast, reduce visible scanner noise, and preserve handwriting, stamps, tables, and marks.
  • Apply a conservative cleanup: improve readability, reduce scanner artifacts, and preserve the original layout, handwriting, stamps, tables, and marks.
