🤖 AI-Powered Image SEO for WordPress
⚡ Automatically generate ALT text, captions, titles, and descriptions for every image on your site — powered by AI, in seconds.
Poor or missing image SEO data hurts your SEO rankings, degrades accessibility, and costs you visitors. The ShortPixel AI Alt Text Generator 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. Disabling this option allows AI-generated data to overwrite existing metadata.
Use parent Post / Page title for image SEO data – Optionally pass the title of the image’s parent post or page to the AI model for more accurate, context-aware results.
General site context – Provide a detailed description of your website to give the AI model additional context, resulting in more relevant and targeted metadata.
🌍 Multilingual Support
100+ languages supported – Select the output language for all generated metadata. 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.
