Najczęściej zadawane pytania
How do I add a watermark to an image online?
Drop your image in, type your watermark text, choose position and opacity, and click Add Watermark. Download the protected image instantly.
Can I control where the watermark appears?
Yes. You can place the watermark in any of five positions: top-left, top-right, centre, bottom-left, or bottom-right.
How do I make the watermark transparent or semi-transparent?
Use the Opacity slider. 100% is fully opaque; lower values (e.g. 40–60%) create a subtle, semi-transparent watermark.
What font size should I use for a watermark?
For large images (2000+ px wide) use 60–100 px. For smaller images use 24–48 px. The live preview shows how it looks before you download.
Are my images uploaded when I add a watermark?
No. Watermark rendering runs entirely in your browser using the Canvas API — your images never leave your device.
