Why seller image prep is a batch problem
Most merchant image work is not one hero edit — it is a queue problem. Product photos need the same canvas size, the same lighter format, the same naming convention, and the same export rules before they can move into a marketplace, storefront, or catalog feed.
The Batch Listing Asset Optimizer handles that whole queue at once. The job is to prepare a pack of upload-ready assets quickly, keep the process on your device, and make any failures obvious instead of hiding them behind a black-box export. Because it is free and browser-based, there are no upload limits or accounts to manage.
How the batch workflow works
Upload a queue of images, choose one export profile, and the tool processes everything locally. You can review per-file status, retry the few failures, and leave with a single ZIP pack that is easier to upload, hand off, or archive. Common profiles include marketplace square, catalog portrait, thumbnail, and branded product exports.
Each pass can resize, convert formats, compress, apply a watermark, and rename files with a consistent pattern. Because the optimizer runs entirely in your browser, the image pack stays on your device the whole time.
