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.

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.
