Correct Image Size on Mercado Livre: 2026 Guide

Dimensions recommended by Mercado Livre

• Main product photo: minimum 500×500 px, ideal 1200×1200 px.
• Aspect ratio: 1:1 (square) for the best result in the grid.
• Accepted formats: JPG or PNG.
• Maximum file size per image: 12 MB.
• Maximum photos per listing: 12 images.
• Store banner (Official Stores): 1200×600 px.

Why use 1200×1200 px instead of just the minimum

Mercado Livre allows photo zoom. Images at just 500×500 px become blurry when enlarged. With 1200×1200 px, customers can see product details, which increases trust and conversion.

How to create a banner at the right size

• Use the Mercado Livre Banner tool on Lumageni.
• The template is already set to 1200×600 px.
• Add text, price, and logo.
• Export as compressed JPG.

What the marketplace does to your image

The platform automatically crops and resizes for every place the photo appears: search results, product page, cart and app. The same image is shown in at least four different ratios, always cropped from the centre. A product touching the edge of the frame suffers most.

Practical rules that avoid rework

• Use a 1:1 square at least 1,200 pixels per side.
• Leave 10% margin around the product so the automatic crop does not cut it.
• Pure white background on the first photo.
• No text on the main image.

How to test if your main photo works

There is a simple honest test: shrink the image to 200 pixels wide and look at it. That is roughly its size in mobile search. If you cannot identify the product at that size, neither will the customer.

Images and returns

A photo that flatters too much raises sales and raises returns even more, and a return costs more than a lost sale. Oversaturated colour and poorly communicated scale are the two most common causes of 'not what I expected'.
