Will my text show up as empty boxes?

No. The watermark is drawn to a transparent image with the fonts on your own computer first, then composited onto the video, so every character renders.

When is a tiled watermark useful?

When you want to discourage re-uploads. A tiled watermark repeats across the whole frame, so it survives cropping.

Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

Do I need to sign up or pay?

💧Add Watermark to Video Online - Text or Logo

Stamp your name, handle or logo onto a video. Text watermarks are rendered with your system fonts, so any script and even emoji come out right; you can also upload a transparent PNG logo. Place it in any of nine positions, or tile it across the whole frame.
