Source: [Allegro — Rules for images in the gallery and in descriptions](https://help.allegro.com/en/sell/a/rules-for-images-in-the-gallery-and-in-descriptions-8dvWB8Y2PIq). Checked 27 September 2026.

- **Size:** At least 500 pixels on the longer side; uploads up to 26 megapixels; images are shown at up to 2,560 × 2,560 pixels, and larger ones are scaled down proportionally
- **File:** JPG, JPEG or PNG (WEBP also through the API or a file); any proportions, such as 1:1, 4:3 or 16:9; only the sRGB profile for full colour fidelity
- **Background:** The thumbnail — the first image — on white, RGB 255.255.255; in the Fashion categories and kids' clothing and footwear, a uniform white or uniform light grey (HSV value V of at least 0.8); other gallery images may use any background
- **Fashion thumbnails:** Allegro's Fashion guidance: clothing on a model, from the front, uncropped, taking up around 80% of the photo height and/or width; shoes, jewellery, watches, purses, backpacks and sunglasses without a model
- **Models:** Models may appear with the product in any category; images in which Allegro recognises a face are hidden from the Allegro Product Catalog and the product change request form
- **Not allowed:** On the thumbnail: watermarks, logos, text, icons, frames or other decorations; in gallery images: added text or your logo
- **AI images:** Under the EU AI Act, AI-generated or AI-modified photos that might appear authentic must be labelled; Allegro names an AI-generated background and virtual models as examples, and its label option adds an AI label to the photo as a watermark

## Allegro, answered.

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

At least 500 px on the longer side, up to 26 MP, shown at up to 2,560 × 2,560; JPG or PNG. Fashion thumbnails: plain white or light grey.

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

Yes. The free [image size checker](https://herofab.app/tools/allegro-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?**

From Allegro — Rules for images in the gallery and in descriptions, read on 27 September 2026. Marketplaces update their rules; the [official page](https://help.allegro.com/en/sell/a/rules-for-images-in-the-gallery-and-in-descriptions-8dvWB8Y2PIq) is the final reference.
