Home/AI Product Photos/Specs compared

Product Image Specs Compared: Amazon, Etsy, eBay, Shopify and Google in one table

Every one of these platforms publishes its own image rules, and nobody publishes them side by side. That is why sellers end up with five exports and one set of source photos. This page puts the five specs in one table, then says which single image set actually satisfies all of them — and where it cannot. All figures come from the platform documentation linked at the bottom, read on 26 October 2026.

Each platform name links to the page that cites its sources. Values read 26 October 2026.

Platform	Minimum	Recommended	Max file	Product fill	Background	AI metadata
Amazon	500 px (longest side)	1,000 px+ to enable zoom	Not published on the current help page	85% exactly	Pure white, RGB 255,255,255	IPTC contains-synthetic-performer, AI people only
Etsy	635 px (first photo)	2,000 px	Keep under 1 MB	No rule	No rule, but one unedited real photo required	No AI tag, but editing may not hide flaws
eBay	500 x 500	1,600 x 1,600	Not stated on the photo guide	Fill the frame, item centred	White or neutral, uncluttered	No tag required; AI backgrounds allowed in-app, sparingly
Shopify	No minimum	2,048 x 2,048	20 MB	No rule	No rule — it is your own storefront	No rule
Google Shopping	500 x 500, mandatory from 31 Jan 2027	1,500 x 1,500 or above	16 MB	75% to 90%	No rule, but borders are banned	IPTC DigitalSourceType required on every AI image

Where the five actually agree

Only one configuration passes every platform in this set: a square master at 2,048 px or above, sRGB, product centred and filling roughly 85% of the frame, on a background of exactly RGB 255,255,255, with no border, no shadow running off the frame, and no text or logo anywhere on the image.

That single image satisfies Amazon's exact-value check, sits inside Google's 75 to 90% band, clears eBay's 1,600 px recommendation and its white-or-neutral guidance, is within Shopify's 5,000 px and 20 MB limits, and is well above Etsy's 635 px floor. Square is the only ratio that is right in all five places.

What it does not do is satisfy Etsy. Etsy requires at least one unedited photo of the real item against a real background somewhere in the listing. No amount of correct pixels substitutes for that, because Etsy is policing honesty rather than geometry.

The three places the specs genuinely conflict

Fill has an upper bound on Google and not on Amazon. Amazon asks for 85%. Google asks for 75% to 90%. An image cropped to 95% passes Amazon and is disapproved by Google, with no visible symptom until the feed reports it.
AI metadata is broader on Google and narrower on Amazon. Google wants IPTC DigitalSourceType on every AI-generated image, including a generated background with no people in it. Amazon wants contains-synthetic-performer only when a photorealistic AI person appears. A generated background needs one tag and not the other.
Background is absolute on Amazon and absent elsewhere. Only Amazon measures the value at 255,255,255 and suppresses the listing when it is off. eBay asks for white or neutral without measuring; Google and Shopify have no background rule at all. The strictest rule wins, which is why Amazon's spec becomes the default everywhere.

The export recipe that survives all five

Shoot or generate once at the largest size you can, square. Do not crop for a platform; crop once, for all of them.
Place the product at 85% of the frame. That number is inside Google's band and is exactly what Amazon asks for, so it is the only fill value that needs no rework.
Set the background to exactly RGB 255,255,255 and verify the corner pixels, not the preview. Sample the four corners after export, because a JPEG save can shift a near-white to 253,253,253.
Export PNG for the master and JPEG for upload, and check the edge for a halo where the background was removed. A pale fringe is the most common silent failure.
Tag the file after export, not before: IPTC DigitalSourceType for Google on any AI-touched image, plus contains-synthetic-performer for Amazon when a synthetic person is in frame. Most tools strip XMP on save.
Keep one unedited phone photo of the real item in the set. It costs nothing and it is the only thing that makes an Etsy listing compliant.

What this table cannot tell you

Whether your image passes. Every figure here is a published requirement, not a measurement of your file. Amazon's fill and background checks are automated and the thresholds in production are not published in full; Google's review is a mix of automated and manual.

Whether the specs are still current. Platform policies change without announcement, and the AI metadata rules in particular are less than a year old on both Amazon and Google. Each page in this set carries the date its sources were read. If that date is old, open the source.

We have not run a controlled test of these platforms' checkers against a shared image set. When we do, the input images and the failure cases will be published alongside the results.
