When reviewing legal contracts, engineering drawings, or marketing collateral, comparing text alone is not enough—layout shifts, missing signatures, or altered image figures require visual pixel-by-pixel inspection.

How to Use the Visual Diff Tool

  1. Open the PDF Visual Pixel & Text Diff Engine.
  2. Upload Document A (Original) and Document B (Revision).
  3. Use the Curtain Slider to drag back and forth and see micro-differences overlayed.
  4. Switch to Pixel Diff Map to highlight changed pixels in bright red.
  5. Check the Word-Level Changes panel for extracted text modifications.
