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.
  • Watermarks are added above existing page content. They do not remove sensitive information or prevent copying.
  • Use PNG or JPEG images. Text uses a standard PDF font; unsupported characters are reported.
