How to prepare product images for an online store
Well-prepared images help people understand a product, reduce hesitation and support a faster mobile experience.
In an online store, the image is one of the first sources of product information. It should show the shape, size, material and details that matter to the shopper.
A good gallery is not only about attractive photography. Files should be prepared for the contexts where they appear: listings, product pages, cart and small screens.
Choose images that explain the product
Use one clear main image and supporting images that answer common questions. Show relevant angles and keep the presentation consistent across products.
- full view
- important detail
- scale or size
- how it is used
- available variations
Keep the composition consistent
A similar background, position and proportion help visitors compare products quickly. Avoid large differences in empty space and check that the subject remains visible after cropping.
For products that need context, add usage photos separately from the main image.
Resize before uploading
Upload images at a size suited to the component where they appear. A very large file does not automatically show more detail on screen, but it can increase loading time.
Keep a high-quality archive version and generate optimised versions for the website.
Use suitable formats and compression
Choose a modern format when the website supports it and compress the image without removing useful detail. Review the result at its actual display size rather than only zoomed in an editor.
Check images on mobile, where connection speed and available space can be more limited.
Write descriptive alternative text
Alternative text should describe the image for people who cannot see it and support the meaning of the page. Mention the product and visible detail without repeating keywords unnaturally.
Decorative images can use empty alternative text when they add no information.
Connect images to product information
The gallery, title, variations, price and availability should describe the same product. Check every variation when colour, size or configuration changes the appearance.
A consistent presentation reduces questions and helps shoppers choose with more confidence.
Check performance after publishing
Test the product page on mobile and check that the main image appears quickly without pushing content or the purchase button down. Also review cropping, zoom, secondary-image loading and alternative text.
Product images support sales when they remain clear, relevant and light for the website.
