Most WordPress sites are missing alt text on over half their images — every one a keyword Google can’t read and a barrier for screen reader users. Image Alt Text fixes this directly from your WordPress dashboard. View every image with or without alt text, edit inline, copy filenames or titles in bulk, and keep your media library fully optimised without touching individual media files. Whether you have 50 images or 50,000, Image Alt Text gives you a clear table view of your entire media library, shows exactly which images are missing alt text, and lets you fix them all in bulk — no page refresh, no clicking through individual media items. Image Alt Text Pro adds AI-powered alt text generation using OpenAI, Google Gemini, Claude AI, and Hugging Face — automatically on every upload, or across your entire library in one click.
