What Is Image Alt Text Generator?

The Image Alt Text Generator helps you create descriptive, accessible, and SEO-friendly alt attributes for your images. Alt text serves two critical purposes: it describes images for visually impaired users using screen readers, and it tells search engines what an image depicts for image search rankings. Good alt text is descriptive, concise (under 125 characters), and naturally incorporates relevant keywords without keyword stuffing.

Why Use Our Image Alt Text Generator?

  • Generates multiple alt text variations for each image
  • Balances SEO keywords with natural, descriptive language
  • Accessibility-compliant suggestions following WCAG guidelines
  • Character length optimization (under 125 characters)
  • Context-aware suggestions based on image description and keywords

Technical Guide

Alt text goes in the alt attribute of the <img> tag: <img src="photo.jpg" alt="Your alt text here">. Best practices: describe the image content specifically, keep under 125 characters (screen readers may truncate longer text), include relevant keywords naturally (not stuffed), don't start with "Image of" or "Picture of", and use empty alt="" for purely decorative images. Google uses alt text as a primary signal for image search rankings. Images with good alt text are also more likely to appear in Google Discover and web search image carousels.

Tips & Best Practices
