Tips
Add context about where the image is used (e.g., product page, blog post) for more relevant alt text.
The "standard" option (under 125 characters) is best for most use cases.
For decorative images that don't convey information, use empty alt text (alt="") instead.
Always review AI-generated alt text — it's a strong starting point but may miss nuances.
Frequently Asked Questions
What is alt text and why does it matter?
Alt text (alternative text) describes images for screen readers used by visually impaired users. It's required by the EU Accessibility Act (June 2025) and improves SEO.
Is this compliant with WCAG and EAA standards?
The AI generates descriptive alt text following WCAG 2.1 Level AA guidelines. Always review the output — AI suggestions are a starting point, not a final answer.
Is this AI alt text generator private? Do you upload my images?
No uploads — ever. The AI model runs on your computer, so your images stay on your computer and nothing is sent to OpenAI, Anthropic, or anyone else.
