Invisible Watermark — Protect Without Branding

The invisible mode embeds your watermark in a way that is almost imperceptible to viewers — a fraction of the opacity, randomly placed, appearing briefly every few seconds. If your content gets stolen, the watermark is still there.

  • Nearly imperceptible overlay
  • Randomized position each flash
  • Traceable copyright proof
  • Auto-tuned low opacity
  • Survives casual re-sharing

Visible vs. Invisible Watermarks

Visible Watermark

A watermark viewers can see — your brand name or logo overlaid on the video at a chosen position and opacity. Great for branding, deterring casual reposts, and making your identity clear on social media.

Invisible Watermark

A nearly imperceptible watermark embedded into the video — very low opacity, small size, randomized position, appearing briefly every few seconds. Viewers won't notice it, but if your content is stolen, it's still traceable back to you.

Why Watermark Your Videos?

  • • Protect your copyright. A watermark is the simplest proof of content ownership.
  • • Build brand recognition. Every share spreads your name or logo to new audiences.
  • • Deter content theft. Visible watermarks make it harder to repost your work as someone else's.
  • • Track leaks. Invisible watermarks let you trace which copy of your video was shared without permission.

FAQ

Does this tool add its own watermark to my video?
No. The only watermark in your exported video is the one you configured.
Is my video uploaded to any server?
No. All processing happens entirely in your browser using local APIs. Your video file is never sent to any server.
What video formats are supported for upload?
The tool accepts most common formats your browser can play — MP4, WebM, and MOV are widely supported.
Can I use an image or logo as a watermark?
Yes. Switch the content type to "Image" and upload your logo. PNG with transparency works best.
