Usage

Upload two PDFs and run. The tool compares page count, file size, copyable text layers and content fingerprints; when text extraction is unavailable it still reports page, size and fingerprint differences with diagnostics. Notes: 1. The 15MB file size limit applies; larger files cannot be processed yet. 2. All processing is done locally in your browser; files are never uploaded. 3. After running, scroll the result preview to review each page.
