Redbubble requires images with a minimum resolution for each product type. For example, a large poster may need 7632×10200 pixels. If your source image is smaller, Redbubble will reject it. ResizeFlow AI-upscales your design to meet these requirements automatically.
Printify requires source images to be at least 300 DPI at the product's print dimensions. For a 16×20 inch poster, that means a minimum of 4800×6000 pixels. ResizeFlow generates files that meet or exceed these specifications.
Yes! ResizeFlow generates multiple aspect ratios and sizes from one source image. This lets you list the same design across posters, mugs, t-shirts, and more — each with the correct dimensions.
The industry standard is 300 DPI at the final print size. This ensures sharp, professional-quality output. ResizeFlow automatically targets 300 DPI for all generated files.
