See every featureJuno Studio lets you offer personalized products without custom development. Build a template with text, image upload, design and choice options, place them on your product photos, and assign it to products. Customers see a live preview as they personalize, and their choices carry through to the order. Option prices are added at checkout.

Customers design directly on the product page — typing text, uploading images or sending print files — while you define the exact print area.
