PDF Duplicate Review

Review duplicate PDFs locally. Find identical files and matching extracted text, then export a CSV report. Originals stay untouched.

Find duplicate PDF files on your device with PDF Duplicate Review, a local PDF duplicate checker for Chrome. Compare a batch of PDFs, review matching groups, and export a CSV report without uploading or changing your documents. Compare PDF files in two clearly separated ways: • Byte-identical files — SHA-256 identifies PDFs whose original bytes are identical, even when filenames or folders differ. • Matching extracted text — PDFs with the same page count and normalized page-by-page text are grouped for visual review. Text matches are review candidates, not proof that documents look the same. Images, signatures, annotations, form values, and layout can differ. Open and compare the originals before taking action. HOW IT WORKS 1. Choose PDF files, choose a folder, or drop PDFs into the extension. 2. Review exact groups, text-match groups, and files that need attention. 3. Download a CSV report if you need a review record. LOCAL AND READ-ONLY PDF content, filenames, paths, extracted text, and hashes stay on your device. The extension does not upload, delete, rename, or rewrite source PDFs. Hosted checkout and license verification are the only remote product functions. PLANS Free: up to 10 PDFs per batch. Pro: EUR 49 once, tax included, for version 1. Pro supports up to 250 PDFs per batch, three active browser installations, and no license expiry. There is no recurring fee for version 1. Deactivate an installation before transferring its activation. Future major versions and unlimited support are not included. A fresh online license check is required before a batch larger than 10 PDFs. Request a full refund within 14 days. A completed full refund deactivates Pro and restores the free 10-PDF limit. Mandatory statutory rights remain unaffected. PROCESSING LIMITS 20 MiB per PDF, 200 MiB per batch, 500 pages per PDF, 20 seconds per file, and 5,000,000 extracted characters per PDF. FILES NEEDING ATTENTION Password-protected, malformed, scanned, image-only, oversized, timed-out, and cancelled PDFs are reported and are never presented as unique merely because they could not be inspected. NOT INCLUDED OCR, image comparison, near-duplicate or semantic matching, automatic deletion, PDF rewriting, cloud storage, AI analysis, and legal or records-management advice.
