The Easiest Way to Compare PDFs

Reviewing document revisions can be tedious. CarePDF simplifies this by creating a smart "Interleaved" view of your files. Instead of switching tabs, you get a single document where the original and revised pages are placed next to each other, making manual review 10x faster.

Why Visual Interleaving?

Automated diff tools often fail with complex layouts or scanned docs. Our approach allows you to:

  • Verify Design Changes: Perfect for proofs, blueprints, and layouts.
  • Spot Text Edits: Quickly read the old and new paragraph in sequence.
  • Check Formatting: Ensure fonts, margins, and spacing are preserved.
  • Universal Compatibility: Works with any PDF, including scans and forms.
