Product Image Sizes for Marketplaces

Produce one master image at 2000 by 2000 pixels and it satisfies Amazon, Etsy, Shopify and eBay at once. Every major marketplace accepts a square image at that size, and each one downsizes it to whatever its own layout needs.

Every marketplace publishes different requirements and changes them quietly. Amazon wants at least 1000 pixels square for zoom and prefers 2000, on a pure white background with the product filling most of the frame. Etsy recommends 2000 square but caps each file at 1 MB. Shopify accepts files up to 20 MB, though anything over 500 KB slows a storefront down.

Marketplace image requirements compared

The pixel requirements are similar across platforms, while the file size caps differ by a factor of 20. Check these values against the current seller documentation, since marketplaces revise them without notice.

Etsy is the constraint that matters. A 1 MB cap on a 2000 pixel square image means compression is required rather than optional, and a photograph exported at quality 100 from a camera will not fit.

Why 2000 pixels square works everywhere

2000 pixels square exceeds every platform minimum and satisfies the zoom feature that drives conversions. Amazon enables zoom at 1000 pixels on the longest side, and most other marketplaces sit below that threshold.

Square also removes a layout problem. Marketplace grids are square, so a portrait or landscape photograph gets padded with white bars or cropped automatically, and automatic cropping frequently removes part of the product. Shooting and exporting square gives you control over what stays in frame rather than leaving the decision to a platform algorithm.

The main image rules that cause rejection

Amazon and Walmart enforce a pure white background on the first image, and both suppress listings that break the rule. White means the colour value 255 for red, green and blue, not off white or light grey.

• No text, logos or watermarks on the main image, including size labels and discount badges.
• No props or accessories that are not part of the product being sold.
• The product must fill 85 percent of the frame on Amazon, which most sellers underestimate.
• No borders, frames or coloured backgrounds on the primary listing image.
• Additional images may show lifestyle shots, scale references and detail views, where the rules relax considerably.

File size affects sales, not just compliance

Heavy images slow product pages, and slow product pages lose shoppers before the page finishes loading. A listing carrying 8 photographs at 3 MB each forces a 24 MB download on someone browsing over mobile data.

Marketplaces mostly re-encode uploaded images for their own delivery, which limits the damage on their own pages. The problem stays with any storefront you control, including Shopify, WooCommerce and your own website, where the file you upload is frequently the file a shopper downloads.

How to prepare a product image set

To produce images that pass every marketplace check, follow these 7 steps.

1. Shoot against a plain white sweep in even light, with the product centred and no shadow touching the frame edge.
2. Crop square, leaving a small consistent margin so the product occupies about 85 percent of the frame.
3. Correct the white balance so the background reads as true white rather than grey or cream.
4. Export a master at 2000 by 2000 pixels in the highest quality your camera software offers.
5. Compress a copy for each platform, targeting under 1 MB for Etsy and under 500 KB for your own storefront.
6. Name files by product code and view, such as sku1234-front.jpg, so bulk uploads map correctly.
7. Check one finished file at full size before processing the rest of the catalogue.

Keeping the 2000 pixel master is the step that saves work later. Platforms change their requirements, and re-exporting from a master takes minutes while re-photographing a catalogue takes days.

Compressing without visible loss

Quality 80 to 85 keeps a product photograph looking clean while cutting file size by 60 to 75 percent. Product photographs compress well because a plain white background contains almost no detail to store.

Watch 2 areas when checking the result. Fine texture such as fabric weave, brushed metal and printed labels softens first, and a white background can develop faint grey patches at aggressive settings. Both problems disappear a few quality points higher, so test one representative photograph before committing a catalogue of 500.

Selling across several platforms at once

Produce the 2000 pixel master once, then export a compressed variant per platform rather than maintaining separate photo sets. Sellers listing on 3 marketplaces otherwise manage 3 versions of every photograph.

The variants differ only in file size and occasionally in format. One batch at under 1 MB covers Etsy, one at under 500 KB covers your own storefront, and the original master covers Amazon and eBay, which accept large files and re-encode them anyway.

How many images each listing needs

Use 6 to 8 images per listing, because conversion improves sharply up to that point and flattens afterwards. Listings with a single photograph consistently underperform, and shoppers who cannot see a product from several angles assume something is being hidden.

A workable set covers the front view on white, a back or reverse view, 2 detail shots of texture or finish, 1 scale reference showing the product held or beside a familiar object, 1 lifestyle shot in use, and 1 image showing what arrives in the box. Marketplaces allow more, though the later images are rarely opened.

Image sizes for mobile shoppers

Most marketplace traffic is mobile, so check every image at phone size before publishing. A photograph that reads clearly on a 27 inch monitor can be unreadable in a 180 pixel grid tile.

Products with fine detail suffer most. A patterned fabric, a thin cable or a small engraved logo disappears in a thumbnail, which is why the main image should show the product large in the frame rather than centred with generous margins. Filling 85 percent of the frame is an Amazon rule and a practical one on every platform.

Handling images from suppliers

Supplier photographs usually arrive at inconsistent sizes and frequently break marketplace rules, so process them before listing rather than uploading directly. Dropshippers and resellers face this on every new product line.

Check 3 things in a supplier set. Watermarks and supplier logos breach the main image rules on Amazon and Walmart. Backgrounds are often light grey rather than pure white, which fails automated checks. Dimensions vary between products in the same batch, producing a ragged grid. Cropping square, correcting the background and resizing to a common master size fixes all 3 in one pass.

Formats each marketplace accepts

JPG is accepted by every marketplace, while WebP support remains inconsistent. Shopify serves WebP natively, whereas Amazon and Etsy expect JPG or PNG on upload.

Use PNG only when a product image genuinely needs a transparent background, such as a graphic that will be composited into a banner. A PNG photograph of a physical product weighs 3 to 5 times more than the JPG equivalent with no visible benefit, and several platforms flatten it to white on upload anyway.

Processing a full catalogue

Batch the whole catalogue rather than editing photographs one at a time, because consistency across a listing set matters as much as any single image. Shoppers comparing 12 products notice when 1 photograph is brighter or larger than the rest.

Drop up to 500 images in at once, or drag a ZIP archive straight from your photographer, and every file is resized and compressed to the same specification. The work runs inside your browser on your own processor, so unreleased product photography and seasonal campaign assets never reach a server. For a catalogue under embargo, that difference is the whole reason to process locally.
