Webby Simple Alt Builder is a WordPress plugin designed to streamline the generation of image alt text using contextual information from within the site. Addressing common challenges such as images lacking meaningful alt text, the manual effort required for large media libraries, and the prevalence of generic filenames, the tool enables more consistent and descriptive alt attributes without relying on AI or external services.
The plugin generates structured alt text automatically during image upload, leveraging signals like the image filename, post or page title, category, and custom keywords. Users can configure which context sources to include and refine output by setting maximum word or character length, specifying ignored words, and defining decorative terms to skip non-essential images such as icons or background assets. Webby Simple Alt Builder also supports manual generation and preview of suggested alt text for individual images, as well as batch processing for older media, ensuring existing alt text is preserved and not overwritten.
Additional features include a frontend fallback that applies generated alt text only when the saved alt field is empty, a media overview to track which images still require attention, and batch size controls to manage processing workload. The plugin offers a clean uninstall option to remove stored settings if desired.
Webby Simple Alt Builder is intended for agencies, editorial teams, and WordPress maintenance workflows where consistent, accessible, and SEO-friendly image descriptions are important across a large volume of content. Developed by Murillo Rennó at Webby, the plugin focuses on practical, context-aware automation for WordPress sites, supporting improved accessibility and streamlined media management without introducing third-party dependencies.
