What OpenCart asks for, covered.
OpenCart's documentation recommends product images between 800 × 600 and 1,200 × 900 pixels and files of 100–500 KB. Herofab's square 2K output is 2,048 × 2,048 pixels and heavier than that, so it is resized and compressed before upload; the JPG download is the lighter file. The suggested first image is a clear front view on a white background, which Herofab's packshot studio delivers: the product alone on a white studio background. OpenCart's recommended sizes are in a 4:3 shape, a ratio Herofab does not offer.
Resize and compress first
Square 2K output is 2,048 × 2,048 pixels, above the 1,200 × 900 pixels at the top of OpenCart's recommended range.
White-background main image
Packshot studio delivers the product alone on a white studio background, the first image OpenCart's documentation suggests.
JPG for photos
OpenCart recommends JPEG for photos; Herofab images can be downloaded as JPG.
