About Add Watermark

Watermarking is an essential technique for photographers, designers, real estate agents, and content creators to establish attribution and discourage unauthorized reproduction of visual work.

Our Add Watermark tool lets you apply either custom text strings (with full font size and color control) or logo images with precise transparency blending. Using our 3×3 placement matrix, you can place badges into corners, along edges, or dead center across the image.

Everything runs in your browser via HTML5 Canvas. Your source photos and brand logos never leave your device, ensuring zero upload latency and complete data privacy.

Common Use Cases

Photography Copyright & AttributionStamp copyright symbols, your name, or your website URL on original photos before posting to social media or client proof galleries.
Brand Logo StampsOverlay transparent PNG company logos on marketing graphics, product mockups, and corporate slide visuals.
Confidential & Draft Document StampingApply semi-transparent 'CONFIDENTIAL' or 'DRAFT' watermarks centered across internal document previews.
E-Commerce & Listing ProtectionProtect marketplace product photography and real estate listings from scraped reuse by competitors.
Notes & Format Guidelines
  • Text watermarks currently use clean system typography. Custom OTF/TTF file uploads are planned for a future update.
  • Watermarking burns the mark permanently into the exported pixel data; preserve your original file as an unwatermarked backup.
  • For logo watermarks, transparent PNG files provide the cleanest visual results without a white box border.

Questions & Answers

Answers to common questions about add watermark.

Can I use a transparent PNG logo as my watermark?

Yes! Switch to the 'Logo' tab and upload your transparent PNG logo. The alpha transparency will blend smoothly over your photo.

How do I make the watermark subtle?

Lower the Opacity slider to 30%–50%. This allows the underlying photo content to show through while maintaining a visible copyright mark.

Can I position the watermark anywhere on the image?

The 3×3 grid allows positioning across all four corners, the four outer edges, or dead center, with customizable margin spacing in pixels.

Are my photos or logos uploaded to your servers?

No. All canvas compositing happens directly inside your web browser. Neither your photos nor your logos are uploaded anywhere.
