Amazon product image requirements before upload

What this guide explains

Learn which product image properties to check before an Amazon listing upload.

• Main images need extra attention because background, transparency, and product framing problems can affect listing quality.
• Image dimensions matter for zoom readiness; small source files should be replaced or resized from better originals.
• Image checks should use the actual local files planned for upload, not only filenames listed in a spreadsheet.

Use file evidence, not filenames or spreadsheet URLs

A listing sheet can reference an image that has since been replaced, recompressed, or exported at a different size. Run the local files through the checker and compare the report with the final upload folder. Pixel dimensions and format are objective checks; visual framing, background, product accuracy, and prohibited elements still need human review.

• Check the main image separately because its rules are often stricter than secondary images.
• Confirm that the longest edge is large enough for the intended detail experience.
• Open transparent files against a contrasting background to reveal unexpected edges.

Treat resizing and quality as different questions

Increasing pixel dimensions does not recreate missing product detail. If the source is soft, heavily compressed, or incorrectly framed, return to a better original. After any crop, pad, or resize operation, inspect the exported result at normal and enlarged views before associating it with a listing.

• Keep an untouched master so marketplace-specific exports can be regenerated.
• Check whether padding or cropping changed the apparent product scale.
• Compare current Amazon guidance for the category before final upload.
