Altovexa

Compress product images to WebP and generate alt text for them. Pages load with lighter images.

Altovexa compresses your product images and converts them to WebP, replacing each original with the optimized copy and restoring your image order afterwards. Images that are already efficiently encoded are skipped and do not count toward your monthly allowance. It can also write alt text for images that have none, applying one AI-written caption across every image on a product. Reports show the file sizes recorded before and after each run, and you can test any product page live.

• Bulk image compression with automatic WebP conversio
• AI alt text written once per product, applied to all its images
• Automatic optimization of every new product you creat
• Live page speed testing on any product page
