The [ShortPixel AI Alt Text Generator](https://shortpixel.com) solves all of this in one lightweight, install-and-forget WordPress plugin. Whether you’re running a blog, an online store, or a large media-heavy website, this plugin analyses your images with AI and generates accurate, SEO-optimised image data, automatically on upload, or in bulk for your entire library. ### 💡 Why ShortPixel AI Alt Text Generator? ### 🧠 AI-Powered Image SEO * **Automatically generate ALT tags** – The AI analyses each image and writes a relevant, descriptive ALT text, improving both SEO and screen-reader accessibility. * **Generate image captions** – Create human-readable captions for every image without any manual effort. * **Generate image descriptions** – Produce rich, contextual descriptions stored in WordPress’s native description field. * **Update image titles with SEO-friendly ones** – Automatically replace generic image titles with SEO-friendly alternatives. ### ⚙️ Smart Settings & Control * **Generate image SEO data on upload** – Automatically trigger AI generation the moment an image is uploaded to your Media Library, based on your configured settings. * **Preserve existing Image SEO data** – When enabled, all existing ALT tags, captions, and descriptions are retained.

The AI will produce ALT texts, captions, and descriptions in the language of your choice, making it ideal for multilingual websites. ### 📦 Bulk Mode * **Generate AI Image SEO in bulk for your entire library** – Process all images in your WordPress Media Library at once. * **Preview mode** – Test and fine-tune AI results before applying new ALT texts and descriptions in bulk. Review what the AI generates for a sample of images before committing to a full library update. ### 🛒 WooCommerce Support * Seamless support for WooCommerce product images. * AI-generated ALT text and descriptions for product gallery images improve product discoverability in search engines. ### ♿ Accessibility * Improve website accessibility by ensuring all images have properly generated ALT text and metadata. * Helps your website comply with WCAG accessibility guidelines. ### External services This plugin connects to ShortPixel services to validate your API key, check your available quota, generate AI-based image SEO data, and optionally create a ShortPixel account or send deactivation feedback when you choose those actions. #### ShortPixel API and AI service Service: `https://api.shortpixel.com/` and `https://capi-gpt.shortpixel.com/` Used for: validating your API key, checking available quota, and generating AI image SEO data such as ALT text, captions, titles, and descriptions.
