CommonLook PDF


CommonLook® PDF, a plugin for Adobe Acrobat®allows users to easily and rapidly check and correct PDF documents and forms to ensure compliance with the United States’ Section 508 regulations and other accessibility standards.

The only PDF editor other than Adobe’s Acrobat recognized in the W3C’s PDF Techniques for WCAG 2.0, CommonLook PDF is significantly faster and more efficient than Adobe Acrobat when verifying and correcting tags in PDF files.

Beyond efficiency and process optimization, CommonLook PDF includes comprehensive auditing of manual and automatic validation points in a definitive CommonLook Report.
