How to Add a Watermark to Images
A completely free, private, interactive client-side tool to stamp your photos with text or custom logos.
Step-by-Step Guide
- Upload Base Image: Drag and drop your main photo into the left panel.
- Choose Watermark Type: Select either "Text" to type a custom copyright notice, or "Logo" to upload your brand's PNG/SVG icon.
- Interactive Editing: Click and drag the watermark directly on the image preview to position it exactly where you want. Use the top handle to rotate it visually.
- Customize Appearance: Adjust the opacity, size, and color using the left settings panel. Or toggle "Tiled Mode" for full-image protection.
- Download: Click "Download Image" to instantly save your high-resolution watermarked file without losing quality.
Is this tool secure?
Yes, 100% private. All image processing and watermarking happens directly inside your browser. Your photos are never uploaded to any cloud server, ensuring your intellectual property remains yours.
Does it reduce image quality?
No. The tool reads your original image dimensions and processes the watermark at full native resolution in the background. The preview you interact with is safely scaled down to fit your screen, but the downloaded file accurately retains its original HD quality and dimensions.
