AltMaster: AI Alt Text SEO

Generate Alt Text For Every Product Image In One Click. Improve Image SEO & Accessibility.

AltMaster writes image alt text for your entire catalog with AI that actually reads each image, or a rule-based alt text template built from vendor, title, SKU, and tags if you'd rather skip AI entirely. Run bulk alt text across store images at once. Rename image filenames so both your alt text and image filenames work for product image optimisation, not just one of them. Follow WCAG alt text guidelines.

• Generate AI alt text that describes what's in the photo, not the product title
• Or build alt text from template like vendor, title, SKU, and tags - no AI needed
• Apply bulk alt text and bulk image editing across your whole catalog in one run
• Rename image filenames in bulk for image SEO and product image optimisation
• Preview every change first, then undo any run or single image, anytime
