▶ Open Tool NowHow to Use — 4 Steps
📁 Upload Images in Bulk
Drag and drop all your target product photos into the upload box. Your images populate a gallery list at the bottom — clicking any thumbnail loads a live, real-time preview of your watermark configuration.
⚙️ Choose Watermark Mode & Adjust Settings
Text Mode: Type your store URL or brand name. Adjust font size, color, and transparency (0–100%) to blend the overlay perfectly.
Image/Logo Mode: Import your transparent PNG logo. Adjust size scaling and opacity to overlay it cleanly across all images.
📐 Grid Alignment or Tiling
Snap the watermark to a 3×3 grid (top-left, center, bottom-right, etc.) with pixel padding controls. For advanced theft prevention, enable Tiling Mode — this repeats your watermark across the entire image in a grid or diagonal pattern, making it impossible to crop or mask out.
⬇️ Batch Render and Download ZIP
Click download and EasySolve batch-renders watermarks onto all uploaded photos at their original high-res dimensions, compressing them directly into a neat ZIP archive in seconds — ready to upload to your store.
💡 Smart Watermarking Guidelines
- Position watermarks over central elements or use tiling to prevent simple cropping
- Calibrate opacity carefully — visible but not distracting
- Use high-contrast colors (white/black) to stay visible against diverse backgrounds
- All processing is local — unreleased product files never touch external servers
