How to Use Compare PDF

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