Good to know

  • The cleaned pages become pictures, so any text layer on them is lost. Run OCR afterwards to make them searchable again.
  • Black and white gives the smallest file and the sharpest text, but photos on the page lose their shades.
  • Pages you don't choose are left exactly as they were.
