Free AI Alt Text Generator: Optimize Your Images SEO
Our AI alt text generator uses artificial intelligence (BLIP vision-language model) to automatically create SEO-optimized alt text descriptions for your images. Improve web accessibility and natural SEO with relevant alt text generated in seconds.
What is Alt Text (Alternative Text)?
Alt text (alt attribute) is a textual description of a web image serving two critical purposes: (1) Accessibility - allows screen readers to describe the image to visually impaired users, (2) SEO - helps search engines (Google, Bing) understand image content and improves ranking. Good alt text is descriptive, concise (125 characters max recommended) and contains relevant keywords.
How Does AI Alt Text Generation Work?
Our tool uses BLIP (Bootstrapping Language-Image Pre-training), a vision-language model developed by Salesforce Research. This AI visually analyzes your image to detect objects, people, actions, colors, context and generates a natural description in French or English. Processing happens 100% locally in your browser via Transformers.js - your images are NEVER sent to our servers.
Why Use an AI Alt Text Generator?

Image SEO Improvement
