Does this video watermark tool upload my video?

No. The video watermark process runs locally in your browser.

Does it preserve the original video resolution?

Yes. The canvas is initialized using the source video resolution so the export keeps the original dimensions.

Can I preview the watermark before export?

Yes. You can preview the watermark on the video before starting the export process.

How this browser video watermark tool works

Upload a video, enter the watermark text, adjust size and opacity, then preview the result. When you export, the watermark is rendered over each frame on a canvas while keeping the original video dimensions.

Why use a moving watermark

A moving watermark is harder to crop out than a fixed corner watermark.
It stays subtle while still identifying the source video.
Changing position every minute helps reduce repetitive screen placement.

Best settings for subtle watermarking

Opacity around 0.30–0.55 works well for most business videos.
Use a neutral font size relative to the resolution.
For bright videos, use black text. For dark videos, use white text.
