What does the checker measure?

It measures size, aspect ratio, real file format, file size, color mode, transparency, edge whiteness, product share of the frame and, if you declare AI generation, embedded XMP and IPTC tags. Rules about text, logos and claims are listed as human checks.

Is my image uploaded when I use the checker?

No. The checker runs entirely in your browser. Your images are decoded and measured locally and are never sent to a server.

What do the colors mean?

Red means the rule is required and the image fails it. Yellow means a warning, recommendation or a rule that is not yet mandatory. Green means the measured value passes. Grey means a human has to check, because the rule cannot be judged from pixels.

Free multi-marketplace product image checker

Product image checker

Drop one or more product images, pick the marketplaces and whether it is a main or secondary image, and the checker shows a platform-by-rule matrix: red for fail, yellow for warning, green for pass and grey for a rule that needs a human check. Everything runs in your browser, so your images are never uploaded. Results use public rules checked as of 2026-10-29.
