Focused review

See which pages changed before opening every detail

A clear summary separates changed, unchanged, added, and removed pages so you can review the important differences first.

Visual evidence

Highlight changes directly on the revised document

Detected regions are outlined on page previews and in the downloadable report, making layout, text, and image changes easier to verify.

Predictable pairing

Compare pages in matching document positions

Page 1 is compared with page 1, page 2 with page 2, and so on. Added or removed pages are identified when one document is longer.
