Any image becomes accurate alt text, a caption and keyword tags.
Three simple steps
Upload an image
Drop in a photo, product shot, screenshot or illustration you need described.
Generate the description
AI reads the image and writes concise alt text, a natural caption and a set of keyword tags.
Copy and use
Paste the alt text into your CMS, the caption into a post, and the tags wherever you organize images.
What the alt text generator does
This tool looks at an image and writes the words that describe it: concise alt text for accessibility and SEO, a natural caption for posts and pages, and a set of keyword tags for organizing and searching your library. It is the same image-understanding step behind image to text, focused on describing a picture rather than reading printed words from it. Instead of writing alt text by hand for every image, you upload, generate and copy.
What you get from every image
- Alt text: a short, factual description for the
altattribute - what screen readers announce and search engines read. - A caption: a natural, readable sentence to display alongside the image.
- Keyword tags: relevant terms to label, group and find the image later.
Where alt text and captions help
Accessible alt text means people using screen readers understand your images, which is also a legal requirement in many places. For search, descriptive alt text gives crawlers context they cannot get from pixels, helping images surface in results. And for large libraries, consistent tags make everything findable. It is useful across blogs, online stores, documentation and social media - including images you make with the AI image generator.
Tips for the most accurate descriptions
Upload a clear, well-lit image so the model can read the scene. Review the output before publishing - keep alt text specific and honest rather than keyword-stuffed, and trim it to the detail that matters. For images carrying important printed text, run image to text as well to capture the words exactly. Using AI images responsibly, including how you describe them, is covered in our AI image safety guide.
