We present a polyfill solution for replacing inaccessible images of molecules with fully web-accessible chemistry diagrams. Thereby marked up bitmap images on a client web site are extracted, server side recognised and semantically enriched to generate scalable vector graphics (SVG) with embedded chemical information. These graphics are then re-inserted into the original web page providing readers with accessibility features such as speech output and interactive exploration together with synchronised highlighting and magnification. Our solution works for most combinations of browsers and screen reading software on all major desktop platforms, and while it is currently only implemented for chemical diagrams, it is extensible to other STEM subject areas.
