Accessible math in PDF – finally!

A long-awaited breakthrough has arrived for digital accessibility: complex mathematical equations in PDF files are now fully navigable and readable by assistive technology using MathML.

This development, aligning creation software, modern PDF standards, compatible viewers and assistive technology, finally closes the accessibility gap between the web and downloadable STEM documents. This is a game-changer for students and professionals with print disabilities, providing rich, structured content instead of inaccessible images.
