Amazon Product Image Requirements: Size, White Background and Batch Prep on Mac

Amazon product image requirements in short

Amazon's core image rules are short. Every listing needs a main image that is a professional photo of the actual product, on a pure white background (RGB 255,255,255), with the product filling about 85% of the frame and no text, logos, watermarks, borders or extra props. Images should be at least 1000 px on the longest side, which is the size that enables zoom on the product page, and Amazon accepts images up to 10,000 px on the longest side.

JPEG is the preferred file format, with PNG, TIFF and non-animated GIF also accepted. Amazon accepts sRGB and CMYK, but sRGB is the safe choice for screen display. These are the well-established rules; Amazon's Seller Central help page on product image requirements is the authority, and some categories add their own style rules.

The rest of this guide covers how to meet those rules consistently across a catalog. If you sell on several channels, the e-commerce image optimization guide shows how one master set feeds Amazon, Shopify and Etsy.

Main image vs secondary images: what is allowed?

The main image is the one shown in search results, so Amazon applies its strictest rules there. Secondary images, also called additional or alternate images, are where you explain the product: other angles, the product in use, scale against a hand or a room, close-ups of materials, what is in the box, and infographics with callouts and text.

Use the additional slots in a deliberate order. A common sequence is the main packshot, then the back or side, then a close-up of the key material or feature, then a scale or in-use shot, then an infographic with dimensions, and finally packaging or what is in the box. A consistent order across a product line makes the whole brand look organized.

Because the rules differ, prepare the two groups as separate presets. The main image preset focuses on background and fill; the secondary preset only needs size, color and file weight.

What size should Amazon product images be?

At least 1000 px on the longest side is the line that matters: below it, shoppers cannot zoom into the image on the product page. Above it, more resolution gives a sharper, deeper zoom, which is why many sellers export at around 1600 to 2000 px or more. A 2000 px square is a practical default: it is comfortably over the zoom threshold, far under the 10,000 px maximum, and quick to upload.

Amazon does not require square images, but square or near-square photos fill the search result tile best, since a very tall or very wide product leaves large white areas. Resize from full-resolution masters in a single step, and avoid upscaling small photos, because zoom exposes the missing detail immediately. The guide to resizing whole folders of photos on Mac covers longest-side resizing in bulk.

How to get a pure white background for the Amazon main image

Pure white means every background pixel is exactly RGB 255,255,255. Photos shot on a white sweep often come out at 240 to 250, a light gray that looks white to the eye but not to a compliance check. You can test any pixel with Digital Color Meter, found in the Utilities folder on macOS: hover over the background and read the RGB values.

There are two ways to get there. The first is in the studio, by lighting the background a little brighter than the product so it records as pure white. The second is in post: cut the product out and place it on a pure white canvas. An offline background remover on Mac does the cutout on-device, which matters if the listing is for an unreleased product.

Operimage's Remove background tool outputs transparent PNG or WebP cutouts, with Smart, Fast, Balanced and Best quality modes and an edge-detail option for hair and fabric. Since Amazon needs an actual white background rather than transparency, place the cutout on a white canvas in an editor such as Preview, export it as JPEG, and check the corners with Digital Color Meter before upload.

File format, color and file weight

Export Amazon images as JPEG in sRGB. JPEG is Amazon's preferred format and keeps files small; sRGB ensures that colors look the same in the listing as they did on your screen, while files left in Display P3 from an iPhone or Adobe RGB from a camera can display less saturated in some places. If a supplier sends CMYK TIFFs from a print workflow, convert those TIFFs to JPG in sRGB first.

Amazon cares more about resolution than about file size, so do not compress aggressively. Zoom magnifies blocky JPEG artifacts and soft edges, so a quality around 85% for a 2000 px image is a sensible starting point. Check a detailed product at 100% in the preview before running the batch.

Also strip camera metadata. EXIF data adds nothing to a listing, and phone photos can include the GPS location where the product was shot; the guide to removing location data from photos shows how to confirm it is gone.

How to name image files for Amazon bulk upload

Amazon's image upload tool in Seller Central matches files to listings by filename. The documented pattern is the product identifier (such as the ASIN, or an ISBN, UPC or EAN), then a period, then a variant code, then the extension. MAIN marks the main image, PT01 to PT08 mark additional images, and SWCH marks a swatch. Do not add spaces, dashes or extra characters to the identifier.

Generating those names by hand for hundreds of files is where mistakes creep in. Rename in the same batch as the resize so every exported file already carries its final name; the product photo naming guide explains how to keep SKU-based internal names alongside Amazon's upload names. Operimage's Rename tool includes an Amazon pack with a live name preview.

Can you prepare Amazon images with built-in Mac tools?

For a few listings, macOS covers the basics. Preview can open a selection of images, resize them together with Tools › Adjust Size so the longest side is 2000 px, and export each as JPEG with a quality slider. Preview's Instant Alpha can remove a simple background on a single image, and Digital Color Meter confirms whether the result is pure white. Finder can batch rename selected files, though building identifier.CODE names for every product by hand is slow.

In Terminal, sips -Z 2000 *.jpg scales every image so its longest side is 2000 px, and sips can convert color to an sRGB profile with its --matchTo option. Remember that sips overwrites the files it processes unless you pass --out with a separate folder.

These tools struggle when a batch mixes backgrounds, sizes and naming at the scale of a full catalog, and each step runs separately. A batch app that keeps cutout, resize, compression and renaming together, with a preview before export, is faster from a few dozen products upward.

A batch workflow for Amazon catalogs on Mac

For more than a handful of listings, set up two presets and run the catalog through them. Operimage, a free Mac app, keeps every step on-device and can save the chain as a Workflow.

• Main image preset: background check or cutout, resize to 2000 px on the longest side, JPEG at about 85%, metadata stripped, Amazon rename pack.
• Secondary image preset: same size and color settings, no background change, sequence codes PT01 onward.
• Folders: one folder per SKU in, one Amazon export folder out, with the source structure kept.
• Safety: originals are never overwritten unless you choose to, so you can rerun the preset after a fix.
• Reuse: a 2000 px square also suits Shopify; Etsy needs a separate 4:3 export.

Amazon image QA checklist before upload

A quick pass over the output catches the problems that lead to suppressed listings or a poor zoom experience. Check at least the main image of every product and a sample of the secondary images.

Troubleshooting Amazon image problems

If an image is rejected or a listing loses its main image, the cause is usually one of these.

• Main image suppressed: the background is near-white, a shadow or reflection reaches the edge, or there is text or a logo. Rebuild on pure white.
• Zoom not available: the image is under 1000 px on the longest side. Re-export from the master at 2000 px.
• Upload does not attach to the listing: the filename does not match the identifier.CODE pattern, or it contains spaces or extra characters.
• Colors look dull: the file kept a wide-gamut or CMYK profile. Convert to sRGB.
• Product looks small in search: it fills far less than 85% of the frame. Crop tighter around the product before resizing.
