FAQ

Can I move the watermark after applying it?

Yes. Change the position or opacity and click Apply again — every render starts from your original image.

Does it support transparent PNGs?

Yes. The watermark is drawn with alpha, so PNG files keep their transparency.

Is the image uploaded?

No. Everything is rendered on a canvas in your browser.
