Why Use Our Secure Video Watermark Tool?

When protecting sensitive or unreleased content, privacy is paramount. Because Clipy Studio operates entirely offline within your browser via WebAssembly, it is the safest way to add a watermark to video online. There are zero uploads, no cloud processing, and absolutely no risk of your intellectual property being intercepted.

Frequently Asked Questions

Can I add a custom text watermark to my video?

Frequently Asked Questions

How do I add a watermark to a video for free?

Upload your video, then upload your watermark image (PNG with transparency works best) or switch to text mode. Position it using the 9-point grid, adjust opacity and scale, then click Process & Download. Everything runs in your browser — free and private.

Can I add a text watermark instead of an image?

Yes! Click the Text toggle in the Watermark card. Type your text, choose a color and size, then position it anywhere on the video. The text is rendered as a transparent overlay and permanently encoded into the output.

Is the watermark permanently embedded in the video?

Yes. The tool creates a new video file with the watermark permanently encoded. Your original video is never modified. The output is an MP4 file you can share anywhere.

What image format should my watermark logo be?

Use a PNG file with a transparent background for best results. The tool also accepts JPEG, SVG, and WebP images, but PNG transparency ensures the watermark blends naturally with your video.
