Details and limits

Numbers follow your selection order, starting at the number you enter. Unselected pages receive no number. The number/last format uses the last number in this new sequence, not the original PDF page count.

Keep your original file and review the export. Signed or certified documents are not supported. Restructuring pages does not support interactive forms and may lose bookmarks, document attachments, or cross-page links. Watermarks and numbers cover content; they do not redact or secure it.
