Frequently asked questions
- Does this compare the visual layout, or just the text?
- Just the text content of each page — formatting, images, and layout changes aren't detected, only what words were added, removed, or changed.
- What if pages were inserted or removed in the middle of the document?
- Pages are compared by their position (page 1 vs page 1, page 2 vs page 2, and so on). If pages shift because something was inserted earlier in the document, everything after that point may show as heavily changed even if the actual content is the same — just on a different page number.
- Does this work on scanned PDFs?
- Only if they already have a text layer. A scanned page with no selectable text has nothing to compare — run OCR PDF on each file first to give them one.
