diffpdfc

Use diffpdfc to compare PDF files using the command line. In a console (i.e., in a Command Prompt window opened by running cmd.exe) enter, e.g., diffpdfc.exe -Hc -r report.pdf old.pdf new.pdf and see any differences highlighted in report.pdf.

This commercial console (command line) program for Windows is ideal for testing, quality assurance, and scripted comparisons. (See also Why Compare PDFs?)

If you require an easy-to-use Windows application, use our DiffPDF application instead.

diffpdfc can say whether two PDFs are the same or different, and it can optionally output one or more reports that show any differences. The reports can be textual in .csv (Excel), .json, and .xml format and visual in .png and .pdf format. Multiple reports can be output at the same time.

Comparisons can be made based on the text regardless of layout, or based on appearance (which accounts for fonts, colors, layout, diagrams, images, etc.) diffpdfc is cloud-free: it runs on your own computer without the size or page limits of online tools—some customers compare PDFs with thousands of pages.

diffpdfc is useful for anyone who needs to compare PDFs, reports, books, or labels—for example, archivists, engineers, journalists, packagers, publishers, researchers, software testers, and translators. diffpdfc is used by many kinds of organization, including banks, insurance companies, and Government.
