Accessible PDF

Not all PDFs are created equal

Converting your documents into PDFs and making them available online does not necessarily mean that everyone is able to read them. In fact, the majority of PDFs online are image based, rendering the information virtually unusable by blind and print disabled users.

Key difference between standard and accessible PDFs

Image-based and text-based PDFs (standard PDFs) are not compatible with assistive technology such as screen readers, which means that your blind and partially sighted customers cannot access the information properly, if at all. When a standard PDF is accessed by screen readers, the technology may not process anything, process only parts of the content, may process text out of order, or process tables improperly, thus making readability and usability almost impossible.

Accessible PDFs make use of accessibility features to function properly with assistive technology and considers the needs of blind and print disabled users. An accessible PDF is structured for the proper and logical reading order for your document, which is one of the most fundamental steps towards accessibility.
