How Image Watermarker Works
This tool adds professional watermarks to your images for copyright protection and branding. The live preview on the right updates in real-time as you adjust settings, so you can see exactly how your watermark will look before applying it.
Features: Text watermarks with custom fonts, colors, and styles. Image watermarks with scaling and rotation. Nine preset positions plus custom positioning. Real-time preview, opacity control, shadows, stroke effects, and multiple export formats.
Tips: Use subtle opacity (30-50%) for discrete protection, higher opacity (80-100%) for strong branding. Position watermarks in corners for minimal visual impact. The live preview shows exactly how the final result will look - no surprises!
