It can act like a quiet CLI checker through exit status, emit a highlighted diff PDF, or open a simple viewer for page-by-page inspection. ### Project history The upstream GitHub repository was created in 2009 and describes diff-pdf as a simple tool for visually comparing two PDF files. The README now labels the project as provided as-is and not actively developed, while still welcoming patches. The project has kept a traditional autotools build and depends on wxWidgets, Cairo, and Poppler. GitHub releases show continuing tagged maintenance from the 0.3 series in 2019 through 0.5.3 in 2026. ### Adoption history diff-pdf became useful to packagers because it fills a precise automation gap: comparing rendered PDFs in CI, document workflows, and release checks where textual diffs do not describe visual output. The README documents installation through Windows release ZIPs, Chocolatey, Homebrew, MacPorts, Fedora/CentOS packages, and openSUSE builds. ### How it is used Common usage is diff-pdf a.pdf b.pdf for an exit code, --output-diff=diff.pdf for a marked-up artifact, or --view for an interactive GUI. That mix makes it useful both in scripts and in manual document review. ### Why package nerds care The package is a good example of Unix packaging around graphical document infrastructure: a CLI front end with GUI mode, native library dependencies, and real value in reproducible document testing. ### Timeline -
