DiffPDF is a program for Windows designed for comparing PDF documents by analyzing text and visual differences. Suitable for a detailed side-by-side comparison, the tool helps to verify documents and reports.
Text-based
There is a scanner that detects differences in textual content between two PDFs, highlighting changes such as word modifications, insertions and deletions. Users can maintain accuracy in document revisions. The application also works well when comparing PDFs based on appearance, spotting variations in fonts, images, formatting and graphical elements. This is helpful for detecting unintended layout shifts.
Overlay
Users can view projects in a dual-panel mode for easy comparison or overlay them to spot subtle changes. Such flexibility improves the efficiency of document review. It is also possible to choose between text, appearance or structure-based comparisons. The utility helps to generate tailored results based on report type and review needs.
At the moment of writing this article, the executable file is not available for free. Still, you may use the toolset without any payments for about three weeks.
