PDF Differ

At PDF Differ, we believe that accuracy and efficiency are key to professional workflows. Our Mac app is designed specifically for designers, editors, and art directors who need a fast, precise, and reliable way to compare PDFs. Whether you’re reviewing design layouts, proofing editorial content, or ensuring print accuracy, PDF Differ simplifies the process, allowing you to catch even the smallest differences effortlessly.

Our Mission
We created PDF Differ to solve a major pain point in the industry: the lack of an intuitive and efficient PDF comparison tool tailored for creative and publishing professionals. Most traditional PDF comparison tools fall short—they struggle with different paper sizes, don’t account for printer’s marks, or fail to provide a side-by-side visual comparison that truly highlights changes. PDF Differ eliminates these limitations by offering both rasterization and text comparison modes, giving users complete flexibility in how they review their files.

What Makes PDF Differ Unique?
✔ Dual Comparison Modes – Use text comparison for precise document proofing or raster comparison to detect even the smallest design changes.
✔ Handles Different Paper Sizes – Compare PDFs with no restrictions on document dimensions.
✔ Ignores Printer’s Marks – Focus on content differences without distractions.
✔ Compare Spreads & Pages – Perfect for editorial teams working on multi-page documents and layouts.
✔ Fast & Intuitive Workflow – No steep learning curve—just drag, drop, and compare.
