The size our tools make for Heureka
2000 × 2000 px, background: as in your photo, product: as large as the margin allows. The image resizer and the AI white background tool use this preset, which follows the rules above.
The Heureka pages we could read do not state: main image background, aspect ratio, product fill, colour, not on the main image and number of images. We leave these out rather than guess.
Rules for some categories
- Fashion (clothing and footwear): Each colour variant has its own image, about 400 x 400 px (160,000 pixels) or more, no watermarks; clothing preferably on a figure, not folded or hung; footwear images show only the shoes.
Other stated rules
- The minimum is 20 x 50 or 50 x 20 px and 30 kB; the maximum is 2 000 kB.
- The image should not have a transparent background.
- Images must be generic: no discount, bonus or product-advantage messages and no awards. A Heureka Marketplace offer with a watermarked image never takes the top position.
- Heureka downloads images from the shop by URL; a new image needs a new URL.
