FAQ
Are my images uploaded?
No. The watermark is drawn entirely in your browser with the Canvas API — your images never leave your device.
Can I change the position and opacity?
Yes. Pick a corner or center, and adjust font size and opacity with the sliders.
Which formats can I save?
You can download the watermarked image as PNG, JPG or WebP.
