About this tool
Alibaba.com Product Image Resizer
Prepare product photos on a 1000 × 1000 canvas. Keep the whole image with padding or crop to fill, adjust the size, and download JPG, PNG or WebP.
This preset is an editable starting size, not a guarantee of marketplace approval. Processing stays in your browser. Fitting adds a canvas behind your photo; it does not remove the photo's existing background.
Example: fit a 1200 × 800 photo to the square preset to keep its proportions and add space above and below. Choose crop to fill only when you can trim the sides without cutting off the product.
