Comparison report

Select an original and revised PDF to prepare a side-by-side comparison report layout. Files remain on your device.

Choose an original PDF and a revised PDF, then select the comparison style and highlight treatment for a clear review report.

Are the PDF files uploaded?

No. This page is a frontend-only interface and does not send selected files to a server.

Does it compare PDFs yet?

The current implementation provides the complete interface only. PDF parsing and comparison processing are intentionally not connected.
