Why the photo carries so much weight
Online, the buyer can neither touch nor try. The photo replaces the shop shelf: it has to answer “what does it really look like”, “how big is it”, “how is it finished”. A blurry photo, an over-retouched one or one that differs from the product received costs you twice: in lost sales, then in returns.
The photo matters to Google too. It is what appears in Google Shopping, Images and Lens; it is often the largest element on the page, the one that sets the perceived loading time. A well-made image serves both the sale and SEO.
The shots to plan for each product
For each product page, we aim for this set of images, in this order:
- Main image: the product alone, from the front or at three-quarters, on a white or very light background, centred, with no text or logo on top. This is the one that goes to Google Shopping.
- In use: the product being used, in its real setting, to help buyers picture it.
- Details: material, stitching, fastening, connectors, label. What reassures on quality.
- Scale: the product held in a hand or next to a familiar object, so its size is no surprise on delivery.
- Variants: one photo per colour or finish actually on sale.
- Box contents: what the buyer receives, accessories included.
Getting the shot right without a studio
A recent phone is enough for most products, provided you take care of the light and the consistency. What makes a shop look professional is above all that every photo looks alike: same background, same framing, same light.
- Light: a large window with indirect light, or two lamps of the same colour on either side. No direct flash.
- Background: a white sheet curved behind and under the product, to avoid a horizon line.
- Stability: a tripod or a rest, for sharp photos all taken at the same height.
- Framing: square format, with the product filling the same share of the image on every page.
- Colour: check on screen that the colour shown is the product’s colour; it is the most avoidable cause of returns.
Supplier photos: what we do, and what we refuse
In dropshipping or resale, the supplier’s photos are often the starting point. As they are, they raise three problems: they are the same as every other reseller’s, they carry logos, badges and overlaid text, and they are often heavy and of mismatched sizes.
Our method on our own shops: start from the supplier photo, cut out the product locally, place it on a plain background, crop it square, remove floating logos and badges, set aside text-heavy infographics, then export two light sizes. And three things we never do:
- Never an image loaded directly from the supplier’s site: it can disappear, change, or slow your page down.
- Never an AI-generated image to represent a product: buyers must receive what they saw.
- Never a photo that shows more than what is sold (accessories not supplied, a colour out of stock) without saying so clearly.
Formats, dimensions and file size: the technical settings
WebP is a format Google designed for the web. According to its documentation, a lossless WebP image is 26% smaller than a PNG, and a lossy WebP image is 25 to 34% smaller than a comparable JPEG, at equivalent quality.
For search, Google recommends several high-resolution images of at least 50,000 pixels (width multiplied by height) for merchant listings. For speed, the principle is never to send a phone an image meant for a desktop screen.
- Export two sizes: a large one for zoom and desktop, a smaller one for thumbnails and mobile. We use 1,200 and 600 pixels square on our shops.
- Encode as WebP, with a JPEG fallback if your platform needs one.
- Declare the width and height of each image in the code, so the page does not jump as it loads.
- Load the main photo straight away, and the others lazily (the loading=“lazy” attribute).
- Name files with useful words: stainless-steel-bottle-750-ml-black.webp rather than IMG_4821.webp.
Alt text and the context of the image
Alt text (the alt attribute) describes the image for visually impaired people and for search engines. Write what the photo shows, simply: “Black stainless steel insulated bottle, 750 ml, cap open”. No keyword list, and no empty phrase such as “product image”.
Google also understands an image through the page around it: the title, the caption, the text next to it. A photo placed near the description that talks about it is better understood than an image isolated in a carousel.
Frequently asked questions
Which image format for an online shop?
WebP, designed by Google for the web: in its lossy version it weighs 25 to 34% less than a comparable JPEG. Keep a JPEG fallback only if your platform needs one.
How do you convert an image to WebP?
Google provides the free cwebp tool, available for Windows, macOS or Linux, which converts a JPEG or PNG into WebP. Many image editors can also export to WebP. Keep the high-resolution original and publish only the resized WebP version.
What size should a product photo be?
Large enough for zoom (Google recommends at least 50,000 pixels for merchant listings), with a smaller version for mobile. We export 1,200 and 600 pixels square.
Can you use the supplier’s photos?
Yes if you have the right to, but reworked: cut out, on a uniform background, with no logos or overlaid text, and hosted on your own site.
Do you need a white background?
For the main image, a white or very light background is the safest choice: it is the one that goes to Google Shopping. Photos of the product in use can have a real setting.
