Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureGoogle and screen readers can't see your product photos: they read the alt text. Writing it by hand for a whole catalog is slow work. PixelUnik looks at each image and describes what that photo shows, different for every angle, in one of seven languages. Review it, ask for another, or save it to Shopify.
Product images often go live with blank alt text, generic filenames, and heavy JPEG files. That makes them harder to find in image search and slows your store. Pixly uses AI to read each photo, propose alt text and descriptive filenames, turn to WebP, and crop to a consistent square. You review every suggestion and approve in bulk, then sync approved images back to your catalog.
- Compress product images significantly without quality loss
- Optimize images to modern WebP format for faster loading
- Batch optimize multiple images at once from your library
- Track optimization history and results in your dashboard
- AI writes alt text and filenames based on what is actually in each photo.
- Review and approve every image before anything goes live in your store
- Auto-Pilot queues new product images for optimization as you add them.
- Store Audit scans your catalog for missing alt text and heavy image files.
