Protecting Digital Property

If you are a photographer, digital artist, or e-commerce seller, posting raw images online makes them vulnerable to theft. Adding a subtle but permanent watermark is the easiest way to assert copyright.

Custom, Browser-Based Watermarking

Our Add Watermark Tool lets you stamp your images with custom text or transparent logos without needing expensive software like Lightroom or Photoshop.

Key Pros

  • Batch Ready: Process high-resolution images rapidly using local device power.
  • Full Customization: Adjust opacity, font size, rotation, and exact placement (e.g., bottom-right corner).
  • Zero Uploads: Your un-watermarked original photos never leave your computer.

How to Watermark

  1. Select Photo: Upload the image you want to protect.
  2. Configure Stamp: Enter your copyright text (e.g., "© Jane Doe 2026") or upload a transparent PNG logo.
  3. Adjust: Tweak the transparency so it doesn't ruin the photo, but remains visible.
  4. Download: Save your secured image.
