Remove Duplicate PDF Pages.

Open one PDF up to 100 MB and 750 pages, then click Find duplicates. The tool compares page size, rotation, rendered appearance and selectable text. Candidate matches receive a second visual check at a higher resolution before they are grouped.

This is a conservative comparison of rendered pages, not a comparison of PDF file bytes and not a guarantee of identical hidden document structure. A changed number, watermark, scan alignment or page dimension can keep two pages separate. Two blank pages can also match. Review the proposed removals before using the result.

Find duplicates groups matching pages without deleting them. The group cards show the page numbers and which copies will be kept or removed. Click a page in a group to preview it and keep that copy instead of the other copies in the same group.

A checked thumbnail means removal; the active preview indicator is separate. Uncheck a suggested removal to keep an additional copy. You cannot mark the final retained copy in a group for deletion. Unique and protected pages have no removal checkbox. For arbitrary page removal, use Remove Pages from PDF.

Keep first is selected initially. Keep last retains the final occurrence of each matching page instead. All remaining pages stay in their original relative order; this tool does not rearrange the document.

Keep all pages clears every removal. Use suggested restores the current first-or-last preference. Changing that preference or running Find duplicates again replaces manual choices. Start uses your reviewed choices without another scan unless the document has not been analysed.

Two pages can look the same while containing different destinations, comments or field values. Pages with PDF annotations, including links and form widgets, are excluded from automatic matching. Documents containing optional content layers are kept without comparison because hidden layers may differ.

A message shows how many pages were excluded. Password-protected PDFs must be unlocked first. Editing any signed PDF changes the document and can invalidate existing signatures; use the unsigned source when possible.

Start removes the selected copies and prepares one PDF. It also runs detection first if you have not used Find duplicates. If nothing is marked, the original PDF is returned without being rewritten.

When pages are removed, the output retains original page objects rather than rasterizing them. Direct internal destinations to a removed copy are redirected to a retained copy. Check bookmarks and navigation in your PDF viewer after editing. The download summary reports removed and retained page counts. File size savings vary; removing duplicate pages is not a redaction or compression service.

The comparison runs on your device and your PDF is not uploaded for processing. Arabic and other scripts are compared as rendered content and existing text; the tool does not translate, rewrite or run OCR on the document.

The limit is one PDF up to 100 MB and 750 pages. Thumbnails load as needed and whole-document checking starts only after you click Find duplicates or Start. Complex image-heavy PDFs take longer. The bounded visual comparison can miss differences smaller than its rendering resolution, so review important documents.
