Before you save

  • Use an unlocked, untagged PDF up to 100 MB and 500 pages. Digitally signed, XFA, scripted and unsupported files are refused. Your original stays unchanged.
  • Highlights, rectangles, text and ink are standard PDF annotations with appearance streams. Reader support for editing them can vary.
  • Annotations do not remove or conceal underlying information securely. Use Redact PDF for that. Text uses a standard PDF font.
