Generate descriptions for WordPress images

Alt Magic Pro sends images to a cloud-based AI service, which analyzes image content and surrounding post context to generate descriptive alt text. Use it for new uploads or images already in your media library, then review and edit the wording before or after applying it. Generated text can support accessibility and image SEO; check that each description fits the image and its role on the page.

Choose images and batch size

Generate text automatically for new uploads, work with individual images, or process existing media in bulk. CSV upload supports batch work across larger libraries. The service reports processing speeds of more than 10,000 images per hour for high-volume processes.

• Generate alt text in more than 150 languages.
• Use WooCommerce product information as context for product images.
• Where supported, generate captions, titles, and descriptions alongside alt text.
• View, edit, and regenerate previously processed images.
• Optionally create descriptive filenames for existing images or new uploads with AI image renaming.

Alt Magic Pro works with Yoast, Rank Math, SEOPress, Squirrly SEO, and AIOSEO. It also has a web app interface. It can scan Brilliant Directories pages and generate alt text, which you must upload to those images manually.

Credits and image data

The service includes 50 free monthly credits for alt text generation and AI image renaming, with additional volume available. It requires an internet connection, an Alt Magic account, and an API key. Image files or URLs are sent to the service for analysis and processing; basic plugin usage events are also transmitted for service improvement. Review the service’s privacy practices and terms before sending image data.
