What it is

AltText.io generates alt text and image metadata for accessibility, SEO, and stock photography through a web service, extension, and API. The homepage says it can produce alt text in over 130 languages. Its API returns image titles, descriptions, and alt text; stock mode adds buyer-focused keywords, with metadata optimized for Getty Images, Shutterstock, Adobe Stock, iStock, and Alamy. The WordPress plugin handles new uploads and can bulk-process existing images; it requires WordPress 5.0 or later and PHP 7.4 or later. Listed integrations include WordPress, Contentful, Hygraph, DatoCMS, Shopify, WooCommerce, and Magento. It accepts PNG, JPG, and WebP images up to 10 MB. Credit use is one per SEO image, two per stock photo, and three per Getty Images metadata image. Monthly credits roll over only when staying on the same plan. The free plan has 25 image credits per month; Silver costs $19 a month and includes 600 credits. Gold costs $49 a month and includes 2,000 credits. Uploaded images are temporarily stored for processing and automatically deleted when generation is complete.
