Despite the available guidelines and tools to build accessible websites, many still fail to be accessible and usable by the blind users. Web content adaptation has been used as an approach to enhance website accessibility by applying automatic transformation techniques. We describe here a system that automatically increases webpage accessibility by applying three different techniques: link enrichment, image enrichment, and navigation enrichment. Preliminary evaluation of these techniques reveals that the prototype successfully eliminates half of the accessibility errors identified by validating tools and it performs equally well regardless of the accessibility compliance level of the website.
