Create Digitally Accessible PDFs
You can add alt text to objects in Affinity documents to describe their visual content. Assistive tools such as screen readers use this information to describe objects to the reader, improving accessibility.
You can set tags for objects with the Tags panel (this panel is usually hidden; you can switch the setting in the Window menu to display it).
In the panel, you can either enter your own alt text or instruct your Affinity program to use the information embedded in the title, description, or headline fields of placed images (via XMP metadata).
All objects that do not count as the main content may be marked as decoration. Screen readers will then ignore these decorations. If an object is selected, the program will show a corresponding note in the panel.
Adding alt text to an object:
- Select the object.
- Carry out the following steps in the Tags panel:
- To set the alt text yourself, choose the option Custom and type your desired alt text in the corresponding box.
- To generate alt text using the metadata of a placed image, select the desired fields (XMP:Title, XMP:Description, or XMP:Headline).
When you later export the PDF file, simply select the option Tagged PDF in order to integrate the alt text in the file.
Marking objects as decoration:
- Select the object.
- Select the option Mark as Decoration in the Tags panel.
