Plain product photos tell shoppers what something looks like. Infographic product images tell them why it matters. For sellers competing on crowded marketplace pages, that difference can move a listing from ignored to bought. Industry data from 2026 suggests listings that combine clean hero shots with well-designed infographic slots convert at two to three times the rate of those relying on photos alone, and meeting full image guidelines on Amazon alone can lift conversion by up to 30 per cent.

The good news: you do not need a designer or expensive software to create infographics that work. You need a clear message, a tidy layout, and the right export settings. Here is how to build images that actually shift product.

What is a product infographic?

A product infographic is a custom-designed image, usually placed in slots two through seven of your image gallery, that combines a product photo with text callouts, icons, and visual elements to communicate a benefit or feature. Think of it as a billboard inside your listing — it must work in two seconds, on a 5-inch phone screen, while a thumb is hovering over the back button.

Common types include:

Why infographics convert better than plain photos

Shoppers scrolling a marketplace are not reading bullet points. Eye-tracking studies have repeatedly shown that buyers look at the image gallery first and the description last, often only checking the bullets after they have decided to buy. If your infographics fail to answer the customer's questions in the gallery, you have lost the sale before they ever scroll down.

Three reasons infographics outperform standalone product photos:

  1. They pre-empt objections. A sizing infographic stops the "will this fit?" hesitation. A material callout stops the "is this real leather?" doubt.
  2. They build perceived value. Listings with polished infographic galleries look like established brands, even when the seller is one person at a kitchen table.
  3. They convert on mobile. Over half of Amazon, Shopee, and Lazada purchases now happen on mobile. A tight, text-light infographic communicates value at thumbnail size; a paragraph of features does not.

The five rules of infographics that convert

1. One image, one job

The most common mistake is cramming five features into one infographic. Shoppers do not study images — they glance. Each gallery slot should answer exactly one question: How big is it? What is it made of? What problem does it solve? Who is it for? If you have six things to say, use six images, not one busy image.

2. Lead with benefits, not specs

"Stainless steel 304 grade" is a feature. "Doesn't rust in the dishwasher" is a benefit. Customers buy outcomes. Use your specs as supporting text under a benefit headline, not as the headline itself. A useful trick: skim your competitors' negative reviews and turn the most common complaints into the headlines on your infographics. If buyers keep saying "the strap broke," your infographic should say "Reinforced strap holds 15kg."

3. Mobile-first typography

Design your infographics on a phone-sized preview before you finalise the desktop version. If headlines are not readable at 400 pixels wide, they will not be readable in the search grid. Aim for headline text that occupies at least 5 per cent of the image height, and avoid thin, decorative fonts that turn to mush at small sizes.

4. Visual hierarchy with whitespace

Give the most important element — usually the product itself or a key benefit headline — the most space and the strongest contrast. Supporting points step down in size. Whitespace is not wasted space; it is the cue that tells the eye where to land first.

5. Brand consistency across the gallery

Use the same two or three colours, the same font family, and the same icon style across all your gallery images. A consistent visual system makes a small seller look like a real brand, and brand recall is what brings buyers back for repeat purchases.

Technical specifications by marketplace

Each marketplace has its own size and format requirements. Get these wrong and your infographics will be downscaled, blurred, or rejected outright.

Marketplace Recommended size Max file size Preferred format Key rule
Amazon 2000 x 2000 px 10 MB JPG (PNG for graphics) Hero image must be plain white background; infographics allowed in slots 2-7
Shopify 2048 x 2048 px 20 MB JPG, PNG, WebP Square crop preferred for product grid consistency
Lazada 1000 x 1000 px (min) 5 MB JPG, PNG Up to 8 images per listing; first must be product on white
Shopee 1000 x 1000 px 2 MB JPG, PNG Square format; up to 9 product images
Qoo10 800 x 800 px (min) 3 MB JPG, PNG Detailed product description page allows long-form infographics
Carousell 1080 x 1080 px 5 MB JPG, PNG Up to 10 images; mobile-first audience

The safest approach for sellers listing across multiple marketplaces is to design a master infographic at 2000 x 2000 pixels and resize down for each platform. Resizing down preserves quality; scaling up never does. Tools like PixelPrep can batch-resize a folder of master infographics into the right size for each marketplace in a single drop, which saves a lot of repetitive export work.

JPG or PNG: which format to use

This trips up a lot of sellers. The right choice depends on what is in the infographic.

Common infographic mistakes that hurt conversions

A simple workflow for non-designers

  1. Plan the gallery on paper first. Write down the seven questions a buyer will ask, and assign one to each gallery slot.
  2. Pull customer language from reviews. Both yours and competitors'. Real buyer phrasing converts better than marketing copy.
  3. Build at 2000 x 2000 in your tool of choice. Canva, Figma, Photoshop, or even PowerPoint all work — the tool matters less than the message.
  4. Test at thumbnail size. Shrink to 200 pixels wide. If you cannot read the headline, redesign.
  5. Export masters as PNG. Keep a lossless original.
  6. Resize for each marketplace. Match the specs in the table above. Batch-process if you sell across several platforms.
  7. Track the results. Most marketplaces show conversion data. If a new gallery design lifts conversion, lock it in; if not, iterate.
