Find Duplicate Pages - Free Online Browser Tool

Detect identical or near-identical pages and report or remove the repeats.

Duplicated pages turn up through merges, through scanning the same sheet twice, and through a template that was already applied. They are hard to spot by eye in a long document and embarrassing to send. This identifies them by comparing content and appearance.

This find duplicate pages utility runs completely inside your web browser.

How to Use the Find Duplicate Pages Tool

Four steps, and the whole thing runs locally on your own device.

  1. Load the document

    Works on anything, but it takes longer the more pages there are.

  2. Choose how strict to be

    Exact compares page content. Near-duplicate also compares appearance, catching pages re-scanned from the same original.

  3. Report or remove

    Reporting changes nothing. Removing keeps the first copy of each group and deletes the rest.

  4. Download

    Removal comes with a list of which page matched which.

Frequently Asked Questions

Why are several blank pages reported as duplicates?

Because they genuinely are identical to each other. A document with blank separator pages will flag them, so check the list before removing.

What is the difference between the two modes?

Exact matches pages that share the same underlying content, which finds duplicates copied during a merge. Near-duplicate also compares how a page looks, which finds two separate scans of the same sheet.

Which copy is kept?

The first occurrence. That is usually the right choice, because in a merge the first copy is normally the original and the rest are the accidental repeats.

Could two different pages be flagged by mistake?

In exact mode, no — it compares content rather than appearance. In near-duplicate mode a coarse visual sample could group two genuinely different but similarly laid out pages, so read the report before removing.

Does this renumber anything?

No. Removing a page leaves the others with their original numbers, which is usually what you want for a document under discussion.
