Product photos: the method for images that sell and load fast

A good product photo shows the item exactly as the buyer will receive it: sharp, on a light background, framed the same way as the other products in the shop, and light enough to appear instantly on a phone. A product page needs four to six of them: the product alone, in use, the details, the scale. Saved as WebP, these images weigh noticeably less than as JPEG or PNG, with no visible loss.

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:

  1. 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.
  2. In use: the product being used, in its real setting, to help buyers picture it.
  3. Details: material, stitching, fastening, connectors, label. What reassures on quality.
  4. Scale: the product held in a hand or next to a familiar object, so its size is no surprise on delivery.
  5. Variants: one photo per colour or finish actually on sale.
  6. 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.

  1. 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.
  2. Encode as WebP, with a JPEG fallback if your platform needs one.
  3. Declare the width and height of each image in the code, so the page does not jump as it loads.
  4. Load the main photo straight away, and the others lazily (the loading=“lazy” attribute).
  5. 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.
