Product image file size limits by marketplace
Short answer: Walmart allows 5 MB per image, eBay 12 MB, Google Merchant Center 16 MB and Shopify 20 MB. Etsy sets no hard maximum but warns that files over 1 MB may fail to upload on slow connections. We count a megabyte as 1,000,000 bytes, the stricter reading, so a file that passes here also passes under the larger definition. The table lists the source of each limit.
No images yet. Results will appear here: red means fail, yellow means warning, green means pass, and gray needs a manual check.
File size limits differ by marketplace, and some are hard caps while others are only warnings. Here is every file size limit in our library, with its source.

- Of the hard caps in our library, Walmart's 5 MB per image is the smallest. Etsy warns above 1 MB but does not enforce a maximum.
- How do I get an image under a file size limit?
- Export as JPEG with slightly higher compression, or scale the image down, then run it through the checker. Do not go below the marketplace's minimum size.
