Remediating a document involves enhancing its accessibility and usability for individuals who are differently-abled. This process identifies and addresses any accessibility barriers within the document, ensuring that people with disabilities can effectively access and utilize its content.
A document is considered accessible when it can be easily read by individuals with vision, hearing, or cognitive impairments, just as it can be by those without any impairments.
Document accessibility benefits diverse audiences by providing clear, straightforward information that is easily understood. Importantly, it ensures usability for a wide audience, including individuals with disabilities and those using various devices, software, and hardware.

Previously, checking document accessibility required substantial manual effort, but now, it can be done with a few clicks using our accessibility checker.
