About SizeMyListing

SizeMyListing is a free tool for online sellers. Drop in a batch of product photos, choose the marketplaces you sell on, and download one ZIP with images sized, framed and named for each of them.

Why we built it

Every marketplace wants product photos in a slightly different size, shape or background. Resizing the same photos again and again for each one is slow. SizeMyListing does it in one pass.

Private by design

All processing happens in your browser. Your photos are never uploaded, so they stay private and there is no waiting for uploads. See our privacy policy.

Where the sizes come from

Each marketplace preset is based on that platform's official seller documentation. Every guide links to its source and shows when it was last checked. Marketplaces change their rules, so if something looks out of date, please check the official page.
