Technical image readiness
Amazon guidance discusses images at least 1,000 pixels on the longest side for zoom, with 1,600 pixels or more described as a stronger working target. More pixels help only when they come from a detailed original.
- Use JPEG for a predictable OpenFileTools export.
- Start with the highest-resolution original available.
- Treat upscaling as a dimensional change, not a quality improvement.
Main image content rules
The main image is more restricted than secondary listing images. It should show the product clearly against pure white, without promotional text, badges, watermarks, or unrelated props.
- Pure white means RGB 255,255,255.
- Show the entire product and what is included in the sale.
- Check product occupancy after padding or cropping.
Secondary images have a different job
Secondary images can explain scale, features, texture, packaging, and real-world use. Do not force every useful lifestyle photo into a main-image template.
- Use alternate angles and close-ups.
- Show the product in context when appropriate.
- Keep claims accurate and category rules in mind.
What OpenFileTools can and cannot check
OpenFileTools can measure dimensions, source type, orientation, and approximate border whiteness. It cannot verify that the photographed item is accurate, that all category-specific rules are met, or that Amazon will accept the listing.
