Does this tool upload my images to a server?

No. All watermarking is done entirely in your browser using the HTML5 Canvas API. Your images never leave your device.

What does opacity control?

Opacity sets how transparent the watermark text is. 100% is fully opaque (solid), while lower values make the watermark more see-through, creating a subtle effect.
