How to Convert PNG to JPG for Amazon Listings
You shot a clean product photo, exported it as a PNG, and went to add it to your Amazon listing — only to hit an upload error or a photo that simply won't go through in Seller Central. It's a frustrating wall when you just want your listing live. The fix is almost always the same: convert the PNG to a JPG, which is the format Amazon actually prefers for product images.

- Click Convert, then download each JPG, or use Download all (.zip) to grab the full set in one file.
Upload the resulting JPGs to your listing and the error should be gone.
Why Amazon prefers JPG for product photos
Amazon's image guidelines list JPEG, TIFF, PNG, and non-animated GIF as accepted formats, but they specifically recommend JPEG for product photographs because it gives the best balance of quality and file size. A JPG of a typical product photo is a fraction of the size of the same image as a PNG, so it uploads faster and stays under the 10 MB cap. Aim to keep the longest side at 1,000 pixels or more so buyers can use Amazon's zoom feature.
PNG is built for graphics with sharp edges, text, or transparency — not for photographs. When you export a photo as PNG, you get a huge lossless file with no real benefit, which is exactly the kind of file that trips up an upload form.
A note on transparent PNGs
If your PNG has a transparent background (common for cut-out product shots), converting to JPG will fill that transparency — JPG can't store transparent pixels, so the see-through areas become a solid background. For Amazon's main image this is usually fine, since Amazon requires a pure white background anyway. But if you were relying on transparency for a layered design, keep a PNG copy or convert to JPG only the versions that need a flat background.
Make the file smaller, too
If a converted JPG is still bigger than you'd like, run it through the free image compressor to shrink it further without visible quality loss. And if a supplier ever sends you photos as .webpfiles that won't even open, the WebP to JPG converter handles those in the same way.
