axesCheck, our web-based PDF Accessibility Checker, provides a first impression of what axesSense can do in the background.

Check PDF accessibility in an automated and scalable way

Checking PDFs for accessibility used to be done one file at a time - for example with axesPDF, the PDF Accessibility Checker PAC, or the web-based axesCheck. With axesSense, you can now automate the whole checking process and check many documents at once.

Automate the testing process

With axesSense, checking PDF files for PDF/UA and WCAG compliance literally runs itself. Check your PDF files from a folder structure or based on a specific trigger event.


Save time

axesSense saves you time twice: on the one hand, it relieves you of manual checking, and on the other hand, evaluations can be specifically aggregated, further processed, and even used again as input for other applications.
