Most marketplaces want a square image of at least 1000 by 1000 pixels, with Etsy favouring landscape for the first photo and Amazon requiring the product to fill most of a pure white frame. Getting this wrong costs you the click before anyone reads a word.
Quick reference
- Etsy: around 2000 pixels on the shortest side, landscape at roughly 4:3 for the lead image, since that is how it crops in search.
- Amazon: at least 1000 pixels on the longest side to enable zoom, pure white background on the main image, product filling roughly 85 percent of the frame.
- eBay: at least 500 pixels on the longest side, though 1600 is far better for zoom.
- Shopify: square 2048 by 2048 is a safe default across themes.
- Poshmark, Depop and Mercari: square, shot on a phone, bright and uncluttered.
Resize without uploading anything anywhere using the Image Resizer. It runs entirely in your browser, so your photos never leave your device.
Why the crop matters more than the resolution
Search results crop your lead image to the platform's own ratio. A beautiful photo composed for a square frame can lose its subject entirely in a landscape crop. Compose for the crop the platform actually uses, then keep a full-frame version for the gallery.
The mistakes that cost clicks
Product too small in the frame, so it disappears at thumbnail size. Inconsistent backgrounds across a catalogue, which makes a shop look unfinished. Files so large that pages load slowly on mobile, where most of your buyers are. And uploading below the zoom threshold, which quietly removes a feature buyers use before purchasing.
One compliance note for Etsy
Background removal that goes beyond a clean swap, such as generative fill or regenerated product areas, counts as AI editing under Etsy's 2026 rules and needs disclosure. See the disclosure guide before you batch-edit a catalogue.
