The builder supports images (JPEG, PNG, BMP, WEBP, HEIC). We recommend uploading high-quality photos in 300 DPI when, possible to avoid blurry or pixelated designs. The software will show a warning sign on the top left of the builder if an image has a lower resolution that may result in poor printed quality. Another message will appear if the “add to cart” button is clicked without updating the image to a high-quality photo.
