Technical Architecture Note:
True semantic text diffing (like Git) is unreliable in PDFs due to absolute coordinate positioning. This tool provides a highly optimized Synchronized Visual Diff. The new Export Diff option mathematically compares the pixels of both documents and generates a visual report highlighting all changes in Magenta. Note that text in the exported diff report is rasterized and non-selectable.
