Can I use my own logo as a watermark?
Yes. Click \"Image\" to upload a PNG with a transparent background. The transparency is preserved when overlaid on your photo. Adjust size (%) and opacity to taste.
Can I add multiple watermarks to one photo?
Yes. Use the + Text or + Image buttons to add as many layers as you need. Each layer can have different positions, text, and settings.
What opacity should I use?
30–50% opacity is the professional standard — visible enough to deter unauthorised use without distracting from the photo. For strong protection, 60–80% works.
Will my watermark appear on the original file?
No. The watermark is applied to the downloaded copy only. Your original file is never modified.
