Performance Max campaigns don't use one fixed ad — Google's system assembles ads on the fly from an asset group of images, headlines, and logos, then serves them across Search, Display, YouTube, Discover, Gmail, and Maps. Fluxx.work generates the image assets that asset group actually calls for, in the sizes Google's automated assembly needs.
Rather than uploading one finished ad, Performance Max asks for a pool of images at square (1:1), landscape (1.91:1), and portrait/vertical formats, plus headlines and descriptions, and it automatically combines them per surface — a landscape image might run in Display, while a square one runs in a Discover feed. Weak or missing formats in the asset group mean Google either won't serve on that surface or will auto-crop what you gave it.
Performance Max campaigns tied to a Shopping feed surface product images inside Search and Shopping placements where viewers are already comparison-shopping. A clear, accurately colored product image without lifestyle clutter tends to serve better here than a stylized scene, since it mirrors the plain product-listing images shoppers already expect on Search.
Google explicitly recommends supplying multiple aspect ratios per asset group because the system has no fallback beyond auto-cropping a single image when a format is missing. Fluxx.work generates square, landscape, and portrait versions from the same product photo up front, so the asset group is complete rather than partially filled.

“I was worried the product would look different across images. The identity lock is real — colours, logo, everything stays pixel-perfect.”

At minimum square (1:1) and landscape (1.91:1) images, with portrait/vertical formats recommended for surfaces like Discover and YouTube Shorts.
Google's system will auto-crop it to fill missing formats, which can cut off part of the product or leave awkward padding.
For Shopping-adjacent placements, a clear, accurately colored product image without heavy styling tends to match shopper expectations better than a lifestyle scene.
Yes — square, landscape, and portrait versions are generated from the same source photo so the asset group is complete.
Fluxx.work fills out the full aspect-ratio set Performance Max asset groups expect, so Google's automated assembly has real creative to work with instead of an auto-cropped fallback.
