Amazon matches bulk-uploaded images to products by the filename: a product identifier, then a slot code, separated by periods - like B0ABCD1234.MAIN.jpg. The renamer builds those names for you: you add products, drop in photos, set the order - and download a ZIP where every file is already named to the convention.
The tool is free, needs no sign-up, and handles as many products in one go as you like - each product with its own identifier and its own set of photos.
The identifier field accepts any of the formats Amazon recognises:
B0ABCD1234;Type it without dashes and spaces - exactly as it must appear in the filename. If the value does not look like a known format, the field turns amber and explains why; such a product is not included in the ZIP until the identifier is fixed.
Every photo in a product has one of three roles, switched in the dropdown on its row:
MAIN), the rest take PT01-PT08 in order;SWCH). Only one per product;Amazon accepts the main image plus up to eight alternates. Anything over that limit is marked in red and left out of the archive.
The order in the list is the order on the listing: the first photo is MAIN, the second is PT01, and so on. Rearrange with the arrows on the left edge of each row - the filenames recalculate instantly, and they also update live as you type the identifier.
The tool checks every photo and says out loud what Amazon may dislike. Warnings do not block the ZIP - they are advice; red issues do exclude the file.
The Download ZIP button packages every ready photo of every product with a valid identifier into one archive. Unpack it and upload the files where you normally upload images in bulk:
Do not rename the files after unpacking: the name is exactly what Amazon matches on. One extra character - and the file will not attach to the product.
Photos are read, checked and packaged on your device: the page sends no network requests with your files, and nothing is stored anywhere. Close the tab - and no trace of your images remains. The ZIP library itself is loaded from this site only when you first press Download ZIP.
