# Product photos ready for Heureka.

Virtual try-on on a white studio background shows clothing worn on a model, the presentation Heureka.cz's fashion conditions prefer, while background removal to white or product studio on white shows shoes on their own; generation is briefed to keep each product's colour, shape, material, logos and details. 2K and 4K output stays within the 4,096 × 4,096-pixel maximum, but a 4K file can exceed the 2,000 kB limit, so the seller compresses or resizes it before it goes into the feed.

Made with Herofab · Remove background

## What Heureka asks for, covered.

### Clothing on a figure

Virtual try-on on a white studio background shows garments worn rather than folded or hung, as Heureka.cz recommends for fashion.

### White, not transparent

Background removal to white matches Heureka's preference, since its feed specification says images should not have a transparent background.

### Watermark-free output

Images made on a plan or with a credit pack carry no watermark, which Heureka blocks and which keeps Marketplace offers out of the TOP position.

### Main image

- **Background colour:** White background (recommended)

**All Heureka image requirements**

Source: [Heureka — Jak správně posílat obrázky](https://sluzby.heureka.cz/napoveda/jak-spravne-posilat-obrazky/). Checked 27 September 2026.

- **Size:** At least 20 × 50 or 50 × 20 pixels and 30 kB, with at least 175 × 175 pixels recommended; at most 4,096 × 4,096 pixels and 2,000 kB
- **Formats:** JPEG and PNG are supported on both official pages; the XML feed specification also lists WebP and BMP, while the image help page says only .jpeg, .png and .jpg are currently supported
- **Background:** Ideally white; the XML feed specification adds that an image should not have a transparent background
- **Clothing and shoes:** Heureka.cz's fashion conditions require a quality image in the matching colour for every colour variant and recommend 160,000 pixels (about 400 × 400) or more; clothing should not be shown folded or hung but ideally on a figure, and a shoe image should show only the shoes
- **Not allowed:** A watermark, a discount or bonus, a specific seller's logo, or any highlight of the product's strengths, awards included; such images are blocked
- **Heureka Marketplace:** A shop in Heureka Marketplace that sends watermarked images does not appear in the TOP position on the product card, even with the best offer; it is shown only in the price comparison
- **Feed:** The main image goes in IMGURL and further views, such as another angle or the whole package, in IMGURL\_ALTERNATIVE; a new image needs a new URL

## Heureka, answered.

**What size should Heureka product images be?**

Heureka feed images: at least 20 × 50 px and 30 kB, 175 × 175 px recommended, at most 4,096 × 4,096 px and 2,000 kB; ideally white, not transparent.

**Can I check my images before uploading?**

Yes. The free [image size checker](https://herofab.app/tools/heureka-product-photo-checker) reads each file in your browser and tests it against these rules; the image is not uploaded.

**Where do these figures come from?**
