Features & Capabilities

Generate accurate, descriptive, and accessible alt text for any image directly from your Firefox browser. Perfect for improving accessibility, visibility in search engines and AI search, and overall content quality.

• Right-click, generate, copy — in seconds Right-click any image on any page and select "AltTextLab: Get alt text." An accurate description appears within seconds with a one-click copy button.

• Auto-copy to clipboard Enable auto-copy in the add-on options, and the generated alt text lands in your clipboard the moment it's ready, with no extra click required.

• Works on any website From product pages and news articles to design portfolios and landing pages, this Firefox add-on works on any publicly accessible webpage.

• Four writing styles to match your content Choose between neutral, descriptive, matter-of-fact, and minimal output styles — so the tone of your alt text matches the content it appears alongside.

• 130+ languages Generate alt text in over 130 languages to support multilingual websites and global teams.

• Improves accessibility for visually impaired users Every accurately tagged image becomes meaningful to visually impaired and low vision users who rely on screen readers, helping your site meet WCAG 2.1 AA accessibility standards.

• Boosts image SEO and visibility in AI-generated answers Accurate alt text helps search engines index your images correctly and increases the chances of your content appearing in AI-generated answers from tools like ChatGPT and Google AI Overviews.

• Privacy-first and GDPR-aligned Images are processed on AltTextLab's servers and immediately discarded — never stored, never retained, and never used to train AI models.

• Free forever plan available Every free AltTextLab account includes 25 free credits per month. When you need more, paid plans start at $5/month.
