Question 1

Does adding a watermark upload the video?

Accepted Answer

No. Watermarking is done locally in your browser; the video and watermark image never leave your device.

Question 2

Does text watermark support Chinese/Japanese, etc.?

Accepted Answer

Yes, it supports any language. Text is rendered using system fonts into a transparent image and overlaid, so Chinese, Japanese, emoji, etc., display correctly without needing to upload fonts.

Question 3

Can I use my own logo as a watermark?

Accepted Answer

Yes. Switch to 'Image Watermark' and upload a PNG (preferably with a transparent background), and you can adjust size, position, and opacity.

Question 4

Can the watermark be removed? Will it affect video quality?

Accepted Answer

The watermark is burned into the video and cannot be separated after export, so please keep the original video. Overlaying requires re-encoding, but high-quality parameters are used, with minimal loss.
