About

GreenOnion is an AI product image generator for Amazon sellers and ecommerce brands. Upload one product photo to create a coordinated, platform-ready image set without prompts, templates, or a photoshoot. For Amazon, GreenOnion produces nine listing images—including lifestyle, benefit, detail, scale, in-use, comparison, and infographic concepts—and six coordinated A+ Content images with supporting headlines and copy. Sellers can review the plan, regenerate individual images, and adapt approved creative across 16 languages. The same workflow supports Etsy and Shopify listing images, lifestyle product photography, on-model fashion photos, and image editing. GreenOnion is designed for sellers, brands, and agencies that need more complete product pages from the photos they already have.

About

SizeSpec prepares product photos and app-store screenshots to meet image requirements for Etsy, eBay, Amazon, Shopify, WooCommerce, Apple’s App Store, and Google Play. Users choose a marketplace preset, add photos, and download a ZIP of images resized, cropped or framed, and compressed to the selected specifications. Each preset links to the marketplace’s published documentation and shows when the requirements were last checked. Resizing, compression and the JPG, PNG, and WebP converters run in the browser; those photos are not uploaded to SizeSpec. An optional AI add-on can improve a product photo (white background, styled surface, better light) or create one from a text description; for this feature only, the photo is sent to the AI provider Higgsfield. Free plan: one marketplace pack per month, up to five photos per pack; converters are free. Premium costs $12/month ($10/month billed yearly) with unlimited packs of up to 200 photos. AI photo credits start at $9.99/month.
