Frequently Asked Questions
What does the Alt Text Generator output?
It produces the text that goes inside an image's alt attribute: a short, descriptive phrase conveying what the image shows and why it matters on the page. You can paste it straight into your HTML or CMS image field.
How does it know what's in my image?
You describe the image and its context in the prompt, the tool then turns that into clean, properly phrased alt text. The richer your description of the subject and the page context, the more accurate and useful the result.
What makes alt text WCAG-compliant?
Good alt text describes the image's meaning and function concisely, avoids redundant phrases like "image of," and leaves purely decorative images with empty alt text. The generator follows these conventions so screen-reader users get a clear, non-repetitive experience.
How long should alt text be?
Keep it concise, typically a short sentence. Screen readers read the whole string aloud, so overly long alt text becomes tedious. The tool aims for a focused description rather than a paragraph; put extra detail in surrounding captions instead.
Does alt text actually help SEO?
Yes, modestly. Search engines use alt text to understand images, which helps them surface in image search and adds relevance context to the page. It's an accessibility feature first, with image-SEO as a genuine secondary benefit.
Should every image get alt text?
Functional and informative images need it; purely decorative images should have an empty alt attribute (alt="") so screen readers skip them. Describe the image's role in your prompt and the tool will phrase it appropriately.
Is it free to use?
