PDF Duplicate Page Finder

When you scan a document or merge multiple PDFs, the same page can appear more than once. Duplicate pages increase file size and make reading confusing. The PDF Duplicate Page Finder helps you visually compare all pages inside a PDF, find identical or highly similar pages, and remove unnecessary duplicates in your browser.

What does this tool do?

• Compares all pages in your PDF visually
• Finds identical and highly similar pages
• Groups duplicates together with similarity percentage
• Shows duplicate page count, group count and pages remaining
• Allows you to adjust similarity threshold from 80% to 100%
• Keeps first page of each group and removes the rest
• Downloads cleaned PDF automatically

Why remove duplicate pages?

Scanned books and contracts often contain repeated scans of the same page. Merged reports or assignments may include the same certificate or invoice twice. Cleaning duplicates reduces file size, saves printing cost and improves reading flow without affecting original quality.

What is similarity threshold?

The threshold controls how strict the comparison is. At 100% only exact duplicates are found. At 98% recommended, pages that look almost the same but have minor scan differences are also detected. Lower values like 80% will find similar but not identical pages. You can move the slider to reduce false detections.
