PDF comparison report

original.pdf → revised.pdf

Extract the ZIP first, then open this report. Red shows detected visual differences, not a percentage of meaning changed.

• Visual comparison uses page images at up to 108 DPI, with the same scale in both files. Fine changes below this resolution or sensitivity may be missed. This is not a check of every PDF object or byte.
• Page pairing is a suggestion. Automatic mode uses unchanged page pictures as anchors and pairs the remaining pages in order. Repeated or moved pages and several edits around an insertion may need manual review. Unpaired pages are labelled added or removed.
• Text comparison ignores whitespace changes and uses selectable words only. Scan text is not recognized. Closed comments, attachments, bookmarks, signature validity and hidden layers are not compared.
