Success Criterion 1.4.5 - Level AA
Images of Text
Do not use images to display text. Always use plain text to allow the text to be adapted to the user's preferences. The font size inside an image often scales to a limited extent or not at all. As a result, the text cannot be read by everyone.
Exception: If an image of text does scale or if text as image is specifically needed to convey information.
Text in an image will not be read by the screen reader. As a result, blind people cannot perceive the text.
When using text in an image, the text scaling preferences of visually impaired people are not taken into account.
“Are no images used to display text?“
This can be tested visually or by using a screen reader.
