The simplest way to improve the accessibility of any PDFs you create is to create your document in another application, such as creating documents in a word processing (e.g. Microsoft Word) or desktop publishing (e.g. Adobe CC InDesign) software with accessibility built in. If needed, these files can then be exported as PDFs, but the ability to build-in accessibility into the native documents will make the exported PDFs more useable. This approach is the most reliable way of achieving optimal accessibility in your PDF documents. If it is necessary to create PDF documents from scratch, there are ways users can ensure they are accessible. Note that this is not recommended – instead aim to create source files in word processing or digital publishing and share with students and others through that format.
If PDFs must be created:
If you have existing PDFs, you can check for accessibility issues and remediate content as required to bring the documents up to standard. This is likely to be the case with PDFs created prior to the introduction of native accessibility checkers in software, or PDFs created by a third-party where the source files are now in the user’s ownership or control.
