Platform requirements

Every image rule, with its source

Image requirements for 22 selling platforms, 177 rules in total, each one marked with where it was read.

22 platforms177 rules131 read at source

The short answer

Each guide states one platform’s image rules as the platform publishes them: pixel size, file type, weight limit, background and colour profile. Every row carries its provenance, so a figure read off the platform’s own help pages never sits in the same type as one that only circulates among sellers. 131 of the 177 rules here come from a primary source.

How these guides are built

  • Every rule is read at the platform's own help or seller documentation wherever that page can be opened, and the page is linked.
  • Where a platform hides its rules behind a login or a bot check, the guide says so and labels the figure as reported rather than published.
  • Each guide names the settings that clear the platform, so you can apply them in any editor rather than only in ours.
  • Photomop is a photo studio that runs on your own device, so a listing photo is never uploaded to us to be resized.

How much is actually published

Which platforms publish their image rules?

The number that matters before you trust any guide, ours included. A platform that documents its rules can be quoted; one that does not leaves every guide on the internet repeating the same unattributed figure.

  • A guide whose count is short of its total is not a worse guide. It is a platform that publishes less, and the guide labels every row it could not stand up.

About this cluster

How platform requirements work

Why some rules are hedged, what size travels furthest, and how often any of it changes.

Why do these guides label some rules as reported?

Because not every platform publishes its image rules. Some sit behind a seller login, some are blocked by a bot check, and some were quietly deleted. Where a figure is not on a page the platform publishes, the row says so and hedges the number rather than printing it as policy.

What image size works across most platforms?

A square 2000 by 2000 pixel JPEG in sRGB, under 1 MB, with no transparency, clears the largest number of the platforms here. It is not the ideal file anywhere, but it is accepted nearly everywhere, which makes it a sound starting point for a listing you plan to cross-post.

Do any platforms accept a transparent PNG?

Fewer than sellers expect. Several render a transparent area as solid black rather than white, which turns a carefully cut-out product into a floating shape in a dark box. Flatten the cut-out onto a solid background before you export, and the problem disappears.

How often do platforms change these rules?

Often, and rarely with an announcement. Every guide carries the date its sources were read and links the page each figure came from, so you can check a number at source in one click rather than trusting a page you found in a search.

Does Photomop have presets for these platforms?

Yes. Each guide names the tool that carries the settings for that platform and states them in full, so you can apply them by hand in any editor if you would rather. The tools run on your own device, at full resolution, with no watermark on the export.

Which platform has the strictest image policy?

The catalogue marketplaces, as a group. They publish the most detail and enforce the most of it, because a listing image there sits in a grid next to competitors and the platform has a commercial reason to keep that grid consistent. Resale apps are the loosest.
