Amazon image resizer (bulk, in-browser)

Prepare large batches of Amazon-ready imagery without paying per-image server fees. Start from a ZIP, apply a preset, and download a ZIP.

Seller teams often receive inconsistent dimensions from studios. Normalizing dimensions before upload reduces rework and keeps zoom behavior predictable.

Use the bulk resize tool and choose the Amazon preset for a fast baseline.

FAQ

Does this upload my catalog to Amazon?
No. The resize tool runs in your browser. You download a ZIP and upload images through Seller Central as you normally would.
What size should Amazon main images be?
Amazon recommends images that are at least 1,000px on the longest side for zoom. The Bulk Toolkit includes a preset aligned to common square workflows.
