Choose a marketplace and drop your photos. Each one is fitted inside the marketplace's recommended dimensions and padded with white — the product is never cut. It runs in your browser; nothing is uploaded. ![Blush satin slip dress on a white background · Marketplace image resizer](https://herofab.app/img/ex/slip-dress-white-1100.webp) Made with Herofab · Packshot studio ## Choose the size. Sizes come from each marketplace's own help pages, summarised in the [guides](https://herofab.app/guides/) (checked 24 September 2026). ## Resizers by marketplace.

The canvas is first filled with the padding colour, white or light grey. The photo is then scaled by a single factor until it fits inside the canvas and is drawn in the centre. Width and height are scaled together, so the proportions stay as they were and nothing is cut. Where the photo and the target differ in shape, the space left over shows the padding colour beside the photo or above and below it. A photo smaller than the target is enlarged, and the result line says so. The file is saved as JPG or PNG; where a channel's size note says JPG only, the format is fixed. Several photos can be dropped together, and each gets a card with the old and new pixel size, the file size, a preview and a download link. ## When to resize, and when another tool fits The resizer suits a photo that is right in content and only has the wrong pixel size or shape. It adds flat padding; it does not continue the scene. A photo whose background has the padding colour blends into it, while a photo taken in a room or on a table gets plain bands next to it. Extend frame is the Herofab tool for that case: it places the image in the middle of a larger canvas and is briefed to continue the background, the floor, the light and the shadows. Enlarging a small photo here adds no detail; Upscale raises the resolution of an image by a factor of two or four. Where the old background should go altogether, Remove background delivers the product on a transparent, white or light grey ground. A file that is still too heavy belongs in the Image compressor, and a HEIC photo the browser cannot open goes through the HEIC to JPG converter first. ## Reading the result and what the tool does not check The line under each file name gives the pixel size before and after and the weight of the new file. The tool fits the whole photo, not the product inside it: it has no setting that finds the product, moves it or changes how much of the frame it fills, so a product that sits small in the photo sits small in the result. The padding colour is laid down before the photo is drawn, so the clear areas of a cut-out take that colour as well, also when PNG is chosen. A correct pixel size meets one rule among several: the file-size limit, the background and the content of the image are judged by the sales channel, and its rule page is the last word. The Image size checker compares a file with the published size and format rules. ## About this tool. **Does this free tool need an account?** The first successful use of each free tool is available without an account. If prompted to continue using it, create a free Herofab account. Files are processed in your browser and are not uploaded. **Is my image uploaded?** No. The file is read and processed inside your browser; nothing is sent to a server. **Is anything cropped?** No. The photo is scaled to fit inside the target size and the remaining space is filled with the padding colour, so the whole product stays in frame. **What happens to the photo's metadata?** Resizing writes a new file, so embedded metadata — camera details, location and any AI-disclosure marker — is not carried over. Herofab images are already delivered at marketplace size and keep their AI marker, so they do not need this tool. **Why is my small photo blurry after resizing?** A photo smaller than the target is enlarged to fit, which cannot add detail. Start from the largest original you have. **Can the product be placed to one side or made larger in the frame?** No. The photo is drawn in the centre of the canvas, scaled as a whole until it fits. The tool has no setting for the position of the photo, the amount of padding or zoom, and it does not detect the product. **Can one batch be resized for two marketplaces in a single run?** Not in a single run. The size, padding colour and format chosen when the photos are dropped apply to every photo in that run. For a second sales channel, choose its size and drop the same photos again. A new run clears the cards of the previous one, so the files are downloaded first.
