Compatible with Windows and Mac (Intel & Apple Silicon). Official website: https://www.nishio.co.jp/pdif/en.html User manual: https://www.nishio.co.jp/pdif/doc-en.pdf
PDiF – Key Features
Compare PDFs as Images PDiF detects even the smallest differences that the human eye might overlook. It allows you to review visual differences across the entire document, including text, graphics, and charts. Blink Comparison Mode Simulates the traditional "blink proofreading" by rapidly alternating between two PDFs. This process is automated, but you can also switch manually if preferred. Compare Multiple Files at Once You can load and compare multiple PDFs or image-based documents in a single operation, streamlining your workflow and saving time. Security You Can Trust PDiF runs entirely on your local PC. It does not upload any files to external servers. Aside from the license check at startup, it doesn’t require an internet connection. Note: Internet is required during license activation. Without it, the software will not launch. Focus Only on What Changed Only the pages with differences are shown, allowing you to focus your attention. Each page is marked with an easy-to-understand ✔ or ✖, showing whether any differences were detected. Supports Image Files Too In addition to PDFs, you can compare image files (JPG, PNG). You can even compare a PDF to an image file directly. Flexible Layout Matching Even if the layouts differ between the two PDFs, PDiF lets you move, rotate, or scale pages in real time to align them for accurate comparison. Handles Page Reordering and Deletion If pages have been removed or reordered, PDiF can still match and compare them effectively. You can insert blank pages to maintain proper alignment during comparison.
