Accessibility is often an afterthought in document design, but for millions of users with visual impairments, it's the difference between being included and being isolated.
What is an 'Accessible' PDF?
An accessible PDF is one that can be easily parsed by screen readers. This means it has a logical structure, alt-text for images, and high contrast for text.
The Problem with Scanned Images
A PDF made purely of JPG images is just a collection of pictures to a screen reader. To make it accessible, you need to use OCR (Optical Character Recognition) to turn those pictures back into selectable text.
When using Kalumbering, we recommend using high-contrast scans to ensure that secondary OCR tools can accurately read your document later.
