What are OTTO's product image requirements?

OTTO images must be JPG or PNG in RGB color mode, at least 500 x 1000 pixels, with a maximum side length of 4500 pixels and filenames free of special characters or umlauts. CMYK is not supported.

What is the minimum OTTO image size?

OTTO's API best practice gives a 500 x 1000 pixel minimum (the onboarding PDF lists 480 x 960); CatalogPrep uses the stricter 500 x 1000. The maximum side length is 4500 pixels.

What background does OTTO recommend for the main image?

OTTO recommends the main image be a cutout or use a light, neutral background such as light grey, white, or off-white. CatalogPrep can add a neutral background and improve product fill.

Does OTTO allow text or energy labels in the product image?

OTTO guidance keeps energy efficiency information separate from the product image. CatalogPrep flags energy-label and text-overlay risk for manual review rather than hard-blocking it.

What file formats and filenames does OTTO require?

OTTO accepts JPG and PNG only, in RGB color mode (not CMYK), and filenames must not contain special characters or umlauts. CatalogPrep converts format, converts CMYK to RGB, and cleans filenames.

What are common OTTO image rejection reasons?

Common issues are CMYK color mode, images below 500 x 1000, a side longer than 4500 pixels, unsupported formats, or filenames with special characters or umlauts.
