AI Image Alt Text Generator
Upload an image for the AI to read directly, or describe it yourself, and get concise, accessibility-focused alt text without turning the alt attribute into a keyword dumping ground.
The core result is calculated in your browser. Optional AI assistance explains the result when available, but it never replaces the underlying calculation or checklist.
What This Tool Does
The core tool combines the visible subject, page context, and important detail you provide into a concise alt-text draft. When you upload an image instead, optional AI assistance reads it directly and drafts a concise alt text, a longer description, and a decorative-image note from what it actually sees.
What the Results Mean
Good alt text communicates the useful visual information needed in context. It should not begin with “image of” or carry unrelated SEO keywords.
What It Does Not Tell You
Reading an uploaded image depends on the optional AI step; if it is unavailable, describe the image yourself instead. The AI can misread small or blurry text and should not be trusted to identify specific people, brands, or exact locations. Uploaded images are sent to an AI vision provider only to generate the description and are not stored by this tool. Decorative images may be better served by an empty alt attribute: alt="".
AI Image Alt Text Generator FAQ
Should every image have descriptive alt text?
No. Decorative images should usually use an empty alt attribute so assistive technology can skip them.
Should alt text contain keywords?
Only when that language naturally describes useful visual content in context.
Can this tool see my image?
When you upload one and AI assistance is available, yes—it reads the image directly rather than relying only on your typed description. Without AI assistance, or without an upload, you need to describe what is visible yourself.
