[Read again · 12 October 2026](https://herofab.app/guides/marketplace-image-rule-changes) - **Main image:** The product page image size defaults to 300 × 300 pixels; an assigned image is scaled so its largest side fits, so a 600 × 400 image becomes 300 × 200 - **Thumbnail:** The thumbnail image size defaults to 150 × 150 pixels and is used on category pages, for related and upsell items and on the home page; 250 is suggested where a responsive theme shows thumbnails too small - **Zoom:** The large image size defaults to 450 × 450 pixels and is the size shown by the built-in 3dZoom option; a range of 600 to 800 pixels is suggested for it - **Resizing:** Images are only reduced to the set sizes, never enlarged; images uploaded by FTP or the file manager and then assigned through a CSV import are not resized by these settings - **Recommended:** Product images are usually best kept to widths of 400 to 600 pixels for display across different screens - **Formats:** Web-linked product images must end in .jpg, .jpeg, .png, .gif, .bmp, .webp or .svg; the image file types allowed for upload to the store are .jpg, .jpeg, .gif, .png, .bmp, .tiff and .tga - **File size:** The file manager accepts files of up to 25 MB each; files over 2 MB or 2,000 × 2,000 pixels usually display cut off when uploaded through it, and FTP is advised for larger files - **Number:** Up to 3 additional images per product, or an unlimited number of images in the product's image gallery; the gallery is for products with more than 4 images - **Background:** A solid, subtle background in light or neutral colours is advised for the main image; in-use and environment shots belong in the additional images - **Alt text:** ALT text is generated automatically from the product name for the primary image only; additional images take a manual ALT tag through the caption field [Check your images — free](https://herofab.app/tools/image-size-checker) ## What Shift4Shop asks for, covered. Shift4Shop only reduces images to its set sizes and never enlarges them; the defaults are 300 × 300 pixels for the product page and 450 × 450 pixels for the large zoom image, with 600 to 800 pixels suggested for zoom. Square 2K output is 2,048 × 2,048 pixels, above all of them. The knowledge base says files over 2 MB or 2,000 × 2,000 pixels usually display cut off when uploaded through the file manager, so a 2K image is resized first or uploaded by FTP; the JPG download is the lighter file. For the main image Shift4Shop advises a solid, subtle background in light or neutral colours, and Herofab's packshot studio shows the product alone on studio white, grey or beige. ### Above every default size Square 2K output is 2,048 pixels per side; Shift4Shop's default large image is 450 × 450 pixels. ### Mind the file manager Files over 2 MB or 2,000 × 2,000 pixels usually display cut off when uploaded through the file manager. ### Light, neutral main image Packshot studio shows the product alone on studio white, grey or beige.
