Why should text be avoided as images?

Text should be avoided as images because it hinders accessibility for screen readers. When text is presented as an image, assistive technologies like screen readers cannot interpret or vocalize the content, leaving visually impaired users unable to access important information. Screen readers rely on textual information that is embedded in the HTML, which they can then read aloud. Images of text do not provide this functionality, thus isolating individuals who depend on such tools for navigating the web.

Providing text in a standard format also allows for features such as rescaling, reflow, and the ability to accommodate various accessibility tools, ultimately fostering an inclusive web environment. When text is rendered as an image, it negates these advantages and can significantly detract from the overall accessibility of the website.
