Remove Duplicate Pages from PDF.

The tool checks more than a thumbnail. It compares page geometry, text information and rendered appearance, then confirms candidate groups at a higher rendering resolution.

Two scans of the same paper may differ through noise, skew or compression and therefore may not match. This is not a fuzzy search for similar topics or wording.

Keep first is the initial preference; Keep last can be useful when later copies are the ones you want to retain. Review the suggested removals before export.

You can adjust choices within a group, but at least one copy must remain. A matching page is not automatically unnecessary in every reading sequence.

Pages with annotations or optional content layers are protected because an identical-looking picture may conceal different comments, links, form values or layers.

If a page is not suggested, do not assume the tool failed to see it. Use a manual page-removal workflow only after you have checked the differences that matter.

The output removes chosen duplicate page objects and redirects references from a removed copy to a retained member of its group. It does not rasterize every retained page.

Check the resulting order and any important links or references. If you keep every page, the tool can return the original bytes unchanged.
