Image Alt Text Generator for Accessibility and SEO
Generate clear image alt text and longer picture descriptions for accessibility, SEO, product pages, blogs, and learning materials.
Alt text helps screen reader users understand important images, and it also gives search engines more context. A good image alt text generator should create concise, accurate descriptions without keyword stuffing.
PictureDescription can help you create short alt text as well as longer image descriptions for accessibility and content workflows.
What good alt text includes
Good alt text usually describes:
- the main subject
- the action or purpose
- important visible context
- text shown in the image, if relevant
It should not repeat nearby captions or include phrases like “image of” unless that wording is useful.
Alt text examples
- “Teacher helping two students with a worksheet in a classroom.”
- “Red running shoes on a grey background.”
- “Person using a laptop beside a cup of coffee.”
Alt text vs long description
Alt text is short and functional. A long picture description can include more detail, mood, background, and interpretation. Use alt text for accessibility attributes and longer descriptions for study notes, content briefs, and image analysis.
