We partner with Sienna to bring high-performance accessibility tools to our PDF suite, including our Contrast presets and the Accessibility Reader.
Accessibility in digital documents is often overlooked. Standard PDF viewers provide static experiences that fail users with visual impairments or dyslexia.
By integrating Sienna's technology, we've enabled our tools to go beyond simple viewing. Our Accessibility Reader reflows text for comfort, while our Contrast & Vision tools ensure that every document is legible for every pair of eyes.
Sienna handles the UI presentation layer of accessibility out of the box.
Scale content up to 200% without loss of meaning or functionality.
