- Upload your Original PDF (Document A) on the left, and your Modified PDF (Document B) on the right.
- Click "Compare Documents" to parse text structures and render visual page layouts client-side.
- Switch between "Visual Side-by-Side" (with synchronous page navigation and a pixel-difference heatmap overlay) and "Text Difference Mode".
- Inspect the highlighted modifications: added lines appear in green, while deleted lines appear in red with strikethrough.
