AI alt text generator for images

In many countries, yes, and the exposure is growing fast. In the US, the ADA (Americans with Disabilities Act) requires websites to be accessible to people with disabilities, and missing alt text is one of the most commonly cited violations. In 2025, over 8,600 ADA website lawsuits were filed, with e-commerce sites making up around 69% of targets. First-time violations can carry fines of up to $75,000, rising to $150,000 for repeat offenses plus legal fees.

The European Accessibility Act (EAA), which came into force in June 2025, extends similar requirements to any business serving customers in the EU. The compliance standard for both is WCAG 2.1 Level AA, and missing alt text is one of the most frequent failure points.

Bulk generation is one of the core use cases AltTextLab is built for. You can process your entire media library in a single run, whether that's a few dozen blog images or tens of thousands of product photos. WordPress, Shopify and WooCommerce users can trigger a full-library batch directly from their CMS dashboard. For developers, the API handles batch requests at scale with no extra configuration needed.

No. By default, AltTextLab only generates alt text for images that currently have an empty or missing alt attribute. Anything you've written manually stays exactly as it is. If you ever want to regenerate alt text across your entire library — including images that already have descriptions — that's available as an explicit, opt-in option. You're always in control.

Yes. AltTextLab lets you provide custom keywords, product attributes, and brand context that the AI factors into its output. This is especially valuable for e-commerce: product images can include the product name, material, color, and category naturally within the description — not stuffed in, but written in a way that reads well for both users and search engines. You can configure keyword preferences at the account level or customize them per batch.

Yes, in two specific ways. Google uses alt text as a primary signal for understanding and ranking images in Google Image Search, which can be a meaningful traffic source for visual businesses. It also adds relevant textual context that helps Google understand the overall topic of your page. For newer AI-powered search surfaces (like Google AI Overviews or ChatGPT), alt text also affects whether your products and images appear in LLM-generated recommendations — a gap that's growing in importance.
