What Is the Alt Text Generator?
Alt text (alternative text) describes images for screen readers and search engines. The Alt Text Generator helps you write descriptive, accessible alt text based on the image context, page topic, and purpose.
Good alt text improves accessibility for visually impaired users and helps your images rank in Google Image search.
How It Works
Describe the image content and context. The tool generates multiple alt text options following accessibility best practices - concise, descriptive, and focused on the image's purpose rather than just its appearance.

Common mistakes to avoid
- Starting alt text with "Image of" or "Picture of"

When not to use it
- For decorative or purely aesthetic images that don't convey information
- When images already have detailed captions that serve the same purpose
Frequently asked questions
How long should alt text be?
Keep it under 125 characters. Screen readers may cut off longer descriptions. Be concise but descriptive - convey what the image shows and why it matters.
Should decorative images have alt text?
No. Purely decorative images should have an empty alt attribute (alt="") so screen readers skip them.
