Description

GreenOnion turns one existing product photo into a coordinated image set for an ecommerce listing. Amazon sellers can generate nine listing images covering the questions buyers ask—what the product looks like, how it is used, what makes it different, how large it is, and why it is worth buying—plus six coordinated A+ Content images with supporting copy. The workflow is prompt-free: upload a photo, review the proposed visual plan, generate the set, and regenerate individual images when needed. GreenOnion also creates Etsy and Shopify listing images, lifestyle product photography, and on-model fashion photos. It is built for sellers and agencies that want stronger product pages without organizing a studio shoot or designing every asset manually.

Description

SizeSpec streamlines the preparation of product images and app-store screenshots by tailoring them to the requirements of platforms like Etsy, eBay, Amazon, Shopify, WooCommerce, Apple’s App Store, and Google Play. Users select a preset for their marketplace, add their images, and receive a ZIP file with images that have been resized, cropped or framed, and compressed for the selected platform. Each marketplace preset links to the official documentation and shows when the requirements were last verified. Resizing, compression, and the built-in JPG, PNG, and WebP converters run directly in the browser, so those photos are never uploaded to SizeSpec’s servers. An optional AI photos add-on, billed separately from Premium, can improve an uploaded product photo (white background, styled surface, or better light) or create a product photo from a description; only for this feature is the chosen photo sent to the AI provider Higgsfield. The free plan allows one marketplace pack each month with up to five images per pack, and the converters are free with no account or usage limit. Premium costs $12/month ($10/month billed yearly) with unlimited packs of up to 200 images each. AI photo credits start at $9.99/month.
