Export diagrams and screenshots from the draft as image files: export labeled figures and high-resolution screenshots …
Open the PDF file in Adobe Acrobat Pro.
Verify that the PDF contains accessibility tags by opening the Tags pane under View > Show/Hide > Navigation Panes > Tags.
CautionIf the PDF is not tagged, accessibility information cannot be preserved in exported images.
Go to File > Export To > Image and select your preferred image format (such as JPEG or TIFF).
In the export dialog, click Settings or Options (if available) and check for any accessibility or metadata retention options; enable them if present.
NoteMost image formats do not natively support PDF accessibility tags, but some metadata may be retained depending on the format.
Complete the export and save the images to your desired location.
For educational accessibility, manually associate alternative text and descriptions with each exported image using your institution’s learning management system or digital asset management tool.
Best practiceA best practice is to export a tag summary or use Acrobat’s Accessibility Report to help recreate accessibility information for each image in your educational platform.
After exporting, review the images and add alternative text in your course platform to ensure accessibility for all students.
This runs in the Acrobat app - there is no separate API for this task.
In Adobe Acrobat, you can export a PDF to images, but you should make sure to use options that keep accessibility tags, like alt text for images. Some formats, like tagged TIFF or PNG, may help, but you might need to manually add tags after export.
Accessibility tagging helps people with disabilities, like those using screen readers, understand the content of images. Without these tags, some users may not know what is in the image.
No, not all image formats support accessibility tags. Formats like JPEG do not keep tags, but some formats like PNG or TIFF can include alt text or metadata if added properly.
If your images lose accessibility tags, you can use image editing or document tools to add alt text or descriptions back in, so everyone can understand the images.
Exporting PDFs to accessible images helps all students, including those with disabilities, access the content equally. It makes sure everyone can understand and use the images in lessons or assignments.
