Frequently asked questions

How are duplicates detected?

Pages are compared by content hash. Visually identical pages are flagged as duplicates.

Will it detect near-duplicates?

No. Pages must be content-identical to be flagged. Minor differences like different page numbers or headers will not be detected.

Which copy is kept?

The first occurrence of each page is kept. All subsequent identical copies are removed.

Can I preview which pages will be removed?

Yes. The tool lists all detected duplicate pages before removal. You can review and confirm before downloading.
