CommonLook PDF Validator

A 100% Free and Complete PLUGIN for Testing PDF Accessibility

Our free PDF Validator combines CommonLooks’ proven PDF technology and feature set into the perfect tool for testing and validating documents.

Fast PDF Verification – Assured!

Unlike other PDF verification products, PDF Validator provides users with a certification report for each tested document. Communications and compliance specialists can rest assured that their PDFs are compliant with accessibility standards. With other verification products, it’s not uncommon that documents will pass the tests, but still not be accessible and compliant.

  • Works as a plugin within Adobe Acrobat
  • Verifies and validates document compliance automatically
  • Only PDF checker that tests against Section 508, WCAG 2.0 AA, PDF/UA and HHS standards
  • Customize checkpoints to each standard, to meet organization’s accessibility needs
  • And it’s Free!

PDF Validator Features

  • View and Verify appropriate Metadata including Title, Subject, Author, Keywords, Language, and Country
  • Verify that the document will display the Title (not the file name)
  • View and Verify accurate Bookmarks
  • Check that fonts are properly embedded in the document
  • Test that characters in text objects are mapped to Unicode
