- Success Criterion 1.1.1
- Conformance level A
Scanned PDF Images With No OCR Text Underneath
1.1.1 — Non-text Content
Scenario
Setting
A childcare-booking service's scheduling page
What’s wrong
PDF images missing /Alt entries — scanned-image PDFs with no OCR text layer.
Example
Watch a childcare-booking service's scheduling page closely and you'll spot this: PDF images missing /Alt entries — scanned-image PDFs with no OCR text layer.
Why it matters
Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning. On a childcare-booking service's scheduling page, this barrier means they miss information that's only conveyed visually.
How to test
Open the PDF's tags panel (Adobe Acrobat Accessibility Checker or similar): images should have /Alt entries — run OCR on any scanned pages to confirm real text exists underneath.
How to fix
Add /Alt entries to PDF images and OCR scanned pages so real text exists.
Outcome
Corrected, a childcare-booking service's scheduling page now lets a visitor understand the image, video, or audio content.
Who is affected
Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning.
