Image Assets Built for Performance Max Asset Groups
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.

How Performance Max assembles ads from your asset group
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.
Product clarity for Shopping-adjacent placements
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.
Covering every required aspect ratio, not just one
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.

“We used to book a studio every quarter. Now one product photo gives us the hero, lifestyle and detail shots in a single pass, and the catalogue finally looks like one brand instead of six separate shoots.”

“The garment is genuinely the same in every frame — colour, print and trims all hold. That was the part I did not believe until we ran our own SKUs through it.”

“Glass and reflections are where most tools fall apart. Ours come out clean, so we can photograph a new scent the week it launches instead of waiting on a studio slot.”

“Metal finish and stone detail survive a zoom now, which is what our listings actually needed. We stopped reshooting pieces that came back soft.”

Frequently Asked Questions
What image formats does a Performance Max asset group need?
At minimum square (1:1) and landscape (1.91:1) images, with portrait/vertical formats recommended for surfaces like Discover and YouTube Shorts.
What happens if I only upload one image format?
Google's system will auto-crop it to fill missing formats, which can cut off part of the product or leave awkward padding.
Should product images for Google Ads look like lifestyle ads or plain listings?
For Shopping-adjacent placements, a clear, accurately colored product image without heavy styling tends to match shopper expectations better than a lifestyle scene.
Can I generate all required formats from one product photo?
Yes — square, landscape, and portrait versions are generated from the same source photo so the asset group is complete.
