Mercado Libre Listing Images: Sizes, Rules and Where the Infographic Goes

Mercado Libre accepts images from 500 × 500 px up to 1920 × 1920 px, recommends 1200 × 1200 px, and switches on its zoom widget once the image is wider than 800 px. The cover photo must sit on a white background with the product filling roughly 95% of the frame and nothing added on top. Descriptions are plain text only, with no images at all, so an infographic has exactly one place to live: carousel positions two onward.

The numbers the platform enforces

Mercado Libre's developer documentation is the most precise thing the company publishes about images. As of August 2026 it sets these limits: JPG, JPEG and PNG; a 500 × 500 px minimum; a 1920 × 1920 px maximum; 1200 × 1200 px recommended; up to 10 MB per file; RGB colour; and a zoom widget that activates above 800 px wide. The photo limit is not one number — it is defined per category and read from the category resource (max_pictures_per_item and its variation equivalent). Most general categories allow ten.

The 1920 px ceiling is the trap for anyone arriving from Amazon, where sets are usually exported at 2000 × 2000 px or larger because Amazon enables zoom from 1000 px on the longest side and recommends 1600 px or more. Push that file to Mercado Libre and it is either rejected or resampled on the platform's terms. Export at 1200 × 1200 px instead.

The cover photo is photography, not design

There is no room for interpretation. The cover sits on white with the product centred, complete and free of hard shadows, and nothing laid over it: no "free shipping", no instalment offers, no price, no shop logo, no watermark, no border, no QR code. Mercado Libre detects overlaid text automatically, and the consequence is not a polite warning but lost rank in the results list.

Category exceptions are real. In apparel, Mercado Libre accepts photographed neutral light backgrounds — grey, cream, beige — and recommends them for white garments, which vanish against pure white. The platform publishes category-specific photo notes for packs, accessories and tops, and those override any general rule. Find the one for your category before you book the shoot.

One more thing that surprises Amazon sellers: Mercado Libre is suspicious of white pasted in during editing. Its guidance asks for photographed white, and its checks flag cut-outs with halos or hard edges.

Plain-text descriptions change the whole plan

Mercado Libre stopped accepting HTML description templates in 2019 and moved to plain text. No images, no tables, no modules. If you come from Amazon, everything you built in A+ Content — comparison tables, dimension diagrams, the what's-in-the-box block — has nowhere to go except the photo carousel, from the second image onward.

That makes photos two through ten the functional equivalent of Amazon's A+ Content, with one difference: they appear in the same carousel as the cover, at thumbnail size, on a phone. The ficha técnica, Mercado Libre's structured attribute sheet, covers specifications and should be filled in completely, but a spec sheet lists rather than argues. The selling argument fits in five or six images and nowhere else.

The rule that follows is about density. An infographic built for Amazon's desktop zoom typically carries six or eight callouts; in a phone-sized carousel that is noise. One idea per image, a five-word headline, type set at 5% or more of the canvas height, and a dimension diagram in second or third position for anything whose size gets misread.

If you compete through Catálogo, images are not your lever

Say this before you spend money. On Catálogo listings, Mercado Libre supplies the content — title, photos, description and ficha técnica. Several sellers compete for the same listing, and the winner is decided by price, reputation, shipping and stock, not by your design. If most of your revenue runs through Catálogo, an image set optimises the wrong variable.

Your design does decide outcomes on your own listings: brands without a consolidated catalogue entry, categories the catalogue has not reached, and variation listings where each variant carries its own cover. Check which model your catalogue sits in before you set a budget.

What has to be rebuilt when an Amazon set moves across

Four things change and one does not. Export size drops to 1200 × 1200 px. Language becomes the Spanish of the country you sell in, with the vocabulary differences that implies between the Mexican, Argentine and Colombian sites. Units and certifications change, because an FDA or CE mark means nothing on a Mexican listing. Density drops, because the carousel is read on a phone. What does not change is the argument: the pain points that came out of your reviews and your category's reviews are identical in both markets. That is why it is worth reusing the research rather than the file — what travels between platforms is the argument, not the JPEG.

How to decide in one minute

1. Do you sell through Catálogo? If that is most of your volume, fix price, reputation and shipping before touching images.
2. Does your cover photo comply? White background, product at 95%, no text. If not, start there — it is the only image that can cost you rank.
3. Do you already have an Amazon set? Then the job is translation and re-cropping, not design from scratch.
4. How many SKUs? Under five, any editor will do. Over twenty, per-image cost and brand consistency decide it.

Common questions

Can I put text on Mercado Libre photos?

Not on the first one. The cover must be on a white background with no text, logos, watermarks, borders or QR codes, and the platform detects overlays automatically. From the second photo onward text, tables and diagrams are allowed, and because descriptions are plain text only, that carousel is the only place an infographic can go.

What image size should I upload?

1200 × 1200 pixels. That is the size Mercado Libre's own documentation recommends, it sits under the 1920 × 1920 px maximum, and it is well past the 800 px width that turns on zoom. The absolute minimum is 500 × 500 px, but at that size there is no zoom and detail is lost.

Can I reuse my Amazon image set?

The argument, yes. The file, no. You have to re-export at 1200 × 1200 px because Amazon sets usually run at 2000 px, translate into the Spanish of the destination country, change units and certifications, and reduce callout density because the Mercado Libre carousel is viewed small and on mobile.

How many photos can I upload?

It depends on the category. Mercado Libre defines the maximum per category in its API, and general categories usually allow ten per listing or per variation. Filling six to eight positions is reasonable: clean cover, dimensions, pack contents, use, materials and a comparison against your own range.

Does Mercado Libre penalise AI-generated images?

What it penalises is an image that misrepresents the product, and its checks flag white backgrounds added in editing with dirty cut-outs. Compositing a real product onto a generated background is a different thing from generating the product itself: the first is routine, the second leads to returns and claims.
