diff-pdf is a command-line tool for visually comparing two PDF files, with options to output a diff-highlighted PDF or view differences in a simple GUI. It is written in C++ and provided as-is with no active development or support.

Use cases

• visually compare two pdf files
• generate a pdf highlighting differences between two pdfs
• check if two pdfs differ in a script via exit code
• compare translated pdfs by shifting pages side by side
• view two pdfs side by side and zoom in on differences

When to choose

• you need visual (rendered) PDF comparison rather than text extraction diff
• you want a scriptable diff tool with a nonzero exit code on differences
• you need a diff-highlighted PDF output for review

When to avoid

• you need active support, bug fixes, or new features - the project is unmaintained
• you only need textual PDF diffing without rendering
• you are unwilling to build from source on platforms without precompiled binaries
