Why Protect and Scale Your Brand Assets?

E-commerce product photos and custom web graphics are frequently scraped, stolen, or copied across competitor marketplaces. Adding a uniform brand logo protects your intellectual property while standardizing image dimensions across your catalog.

  • Brand Theft Protection: Stamp custom PNG transparent logos across hundreds of product photos simultaneously.
  • Glossy Frosted Glass Effects: Lower watermark opacity and apply smooth Gaussian blur so the underlying image detail shines through naturally.
  • Uniform E-commerce Resizing: Automatically downscale oversized camera captures to consistent max pixel widths (e.g., 1200px) to optimize site speed.

Key Features of Our Tool

  • 100% Local & Secure: No web uploads required. Keeps proprietary manufacturing and product assets private on your local PC.
  • Advanced Overlay Controls: Choose 5 placement anchors (Bottom-Right, Bottom-Left, Top-Right, Top-Left, Center) with responsive scaling.
  • Frosted Blur & Grayscale Modes: Convert colored logos to clean black-and-white or apply adjustable frosted glass blur effects.
  • Multi-Format Compatibility: Seamlessly processes JPG, JPEG, PNG, and WebP images in seconds.

Step 4: Configure Visual Effects

Set your desired logo position and scale percentage. Adjust the Opacity / Glossy Slider (e.g., 65%) to allow image details to bleed through under the watermark. Optionally enable Grayscale or Frosted Blur mode.

Step 5: Set Optional Max Width Resizing

Check the Max Width Resize box and enter your target pixel width (e.g., 1200px) to standardize large camera captures.

Frequently Asked Questions (FAQ)

Can I make the watermark look semi-transparent and frosted?

Yes! Adjusting the Opacity slider down to 50–70% and checking the "Frosted Blur" box makes the underlying image visible through the logo for a high-end glossy appearance.


Will my original high-res photos be overwritten?

No. The original source files are preserved untouched. All stamped and resized assets are saved into a separate watermarked_output sub-folder.
