Watermark Image

100% Private. Watermark compositing is processed directly on your device with no uploads.

No paywalls. Unlimited watermarking with custom text and logo support.

Brand protection and copyright stamps

Watermarking prevents unauthorized content redistribution and ensures attribution when your images are shared on social media, portfolio websites, and client proofing galleries.

WebpForge renders stamps with subtle drop shadows and alpha transparency, keeping the watermark legible across both dark and light photographic regions without obscuring your subject.

  • Text Watermarks: Stamp copyright notices (e.g. © 2026 Studio) with automatic font scaling.
  • Logo Overlays: Upload PNG logo graphics with preserved transparency channels.
  • Tiled Pattern Mode: Create repeating diagonal watermark grids for full-canvas proofing security.

Frequently asked questions

How do I add a text watermark to my image?

Upload your image, choose "Text stamp" in the control bar, enter your custom copyright or brand text, and pick a corner or tiled pattern. You can adjust the opacity slider in real-time.

Can I use a transparent PNG logo as my watermark?

Yes. Select "Logo image" in the Watermark type dropdown and choose your transparent PNG logo. WebpForge overlays the logo with customizable transparency and automatic scale fitting.

Are my original photos or watermark logos uploaded to any server?

Never. The compositing process takes place entirely on an HTML5 canvas inside your local browser memory. Files are never transmitted across the network.

Does watermarking reduce the resolution of my photo?

No. Watermarks are drawn at the image’s full native sensor resolution, ensuring crisp typography and sharp logo graphics when saved.
