PDF Duplicate Page Finder
Upload your PDF and instantly see which pages are duplicates, which are similar, and which are blank no download or install needed.
A long PDF built from scanned pages or merged files often hides duplicate pages you’d never spot by scrolling through manually. This tool scans every page, compares both the text and the visual layout, and flags exact duplicates, near-identical pages, and blank pages so you know exactly what’s in your document before deciding what to do about it. Everything is processed locally in your browser. No upload to a server, no sign-up, completely free.
Quick Answer

What is a PDF Duplicate Page Finder?
A PDF Duplicate Page Finder is a tool that scans a PDF and identifies pages that repeat without changing or removing anything from the file. It checks each page two ways: by comparing the actual text content, and by comparing a visual fingerprint of how the page looks, so it can catch duplicates even when a page was rescanned or slightly shifted. Beyond exact duplicates, it also flags pages that are only partially similar (useful when two versions of a page differ slightly) and pages that are blank. This tool only finds and reports it doesn’t delete anything, which matters when you want to review what’s duplicated before deciding what to keep.
When Would You Use This?
Use case 1:
You’ve merged several scanned documents into one PDF and suspect some pages were scanned twice, but don’t want to check hundreds of pages by hand.
Use case 2:
You’re reviewing a long report or contract and need to confirm there are no accidentally duplicated or blank pages before submitting it.
Use case 3:
You received a PDF from someone else and want to verify its contents are clean before relying on it or forwarding it further.
Use case 4:
You want to know exactly which pages are duplicated before deciding whether to remove them reviewing first, acting second.
Frequently Asked Questions
Does this tool remove the duplicate pages it finds?

Can it detect blank pages too?
Yes, blank or visually empty pages are detected and flagged separately from duplicates and similar pages.
Does this tool upload my PDF to a server?

Is there a page limit?
You can scan very large PDFs; for files with more than 500 pages, the tool will ask you to confirm before scanning, since it may take longer.
Can I download a report of what was found?
Yes, click “Download report” to get a text file listing every duplicate, similar, and blank page detected.
