- HTML can be read without problem by screen readers, so it’s a great format to provide students with in addition to PDF documents.
- Some screen readers do not support PDFs, so students using these assistive technologies may not be able to access class materials if they are only available as PDFs.
- Additionally, some PDF documents are encrypted for security purposes in a way that locks out users’ assistive technologies.
- Although PDF documents can be made more accessible, the process can be a hassle and cannot provide the same level of accessibility that an HTML file can.
