Start with a good shot
Use natural light near a window, keep the product in focus, and shoot against a simple background. Good lighting and sharp focus matter far more than an expensive camera — a modern phone is plenty. Take a few angles so you have options.
Remove the background
A clean, consistent background makes a shop look professional and lets the product stand out. Removing the background gives you a transparent cut-out you can drop onto white or a branded colour. This is the single biggest upgrade to most product photos.
Resize and add a watermark
Resize each photo to the dimensions your marketplace recommends so nothing gets cropped. If you want to protect your images from being reused, add a subtle watermark with your shop name. Then compress the final files so your listings load quickly.
