Who Is It For

Indispensable for omnichannel sellers listing the same product on multiple marketplaces, social commerce teams producing daily ad sizes, and agencies delivering platform-specific asset packs to brand clients.

What It Does

The Marketplace Resizer takes your master packshot and generates channel-correct crops and dimensions: Amazon 2000×2000 (1:1) for zoom, Shopify 3:4 gallery ratios, Instagram feed and Story 9:16, Pinterest 2:3, and print lookbook bleeds. Padding, framing, and shadow placement are recomputed so nothing important is cropped off.

When to Use It

Run it at listing time for each new marketplace, when a channel changes its image specification, before paid campaign launches that need 5+ ad aspect ratios, and when preparing seasonal print materials from the same photo set.

Where It Fits

Outputs match Amazon, Shopify, Etsy, eBay, Instagram, TikTok Shop, Pinterest, and print lookbook specifications — one master file becomes a complete multi-channel asset kit.

Why Choose This Tool

  • Meet every platform spec without manual canvas math
  • Smart composition — garment stays centered, shadows stay natural
  • Zoom-capable Amazon 2000px+ exports in one click
  • One master photo becomes a full multi-channel asset kit
