▶ Open Tool NowHow to Use — Step by Step
📂 Upload Your Product Photo
Click the upload area or drag-and-drop your master product image. Any common format (JPG, PNG, WebP) is accepted. Your file never leaves your device.
⚙️ Choose Cover or Contain Mode
Cover fills the square frame edge-to-edge (some outer edges may be cropped). Contain fits the full product inside the frame, filling empty space with a custom background color (typically white) so no part of the product is cut off.
🔍 Adjust Scale & Position
Use the real-time zoom slider to resize the image inside the viewport. Drag with your mouse or finger to center the product perfectly before exporting.
🎨 Pick a Background Color
When using Contain mode, choose any background fill color. A clean solid white (#FFFFFF) is recommended for most marketplace listings to meet platform guidelines.
📦 Download All Sizes as ZIP
Click Download. The tool instantly generates the Coupang preset (1000px), Smartstore preset (1000px), and Instagram preset (1080px) and bundles them into a single ZIP file — all from browser memory, no server required.
💡 Tips & FAQ
- Which mode should I use? Use Contain for products with complex silhouettes (clothing, accessories). Use Cover for bold, edge-filling hero shots.

- What image sizes are generated? Coupang & Smartstore: 1000×1000px. Instagram: 1080×1080px. All outputs are high-resolution.
- Can I use this for eBay or Amazon? Yes — the 1000px outputs meet most major international marketplace requirements (eBay, Amazon, Etsy).
