PDF Visual Diff

Compare PDFs visually and structurally with per-page masks and summaries.

Spot every change between two PDFs. Compare documents visually and structurally with per-page masks, text and object diffs, and signature checks — then read a clear, human-readable summary of what actually changed.

  • Visual, pixel-level PDF comparison
  • Per-page masking to ignore expected regions
  • Text and object-level diffs
  • Digital signature checks
  • Human-readable change summaries
