Frequently asked questions
Can I watermark confidential files safely?
Yes — the file is processed in your browser and never uploaded.
Can I use my own logo?
Yes — switch to “Image / logo” and upload a PNG or JPG; a transparent PNG works best.
Can I change where the watermark sits?
Yes — choose diagonal, horizontal, or tiled, and adjust the color and opacity.
