About Image Watermark Tool
The Image Watermark tool allows you to protect your images and documents by adding visible text watermarks directly in your browser. No file is ever uploaded — everything stays on your device.
Key Features
- Text watermark: Add custom text to any image
- Repeat mode: Perfect for confidential documents
- Client-side only: 100% private & secure
- Export formats: PNG (lossless), JPG or WebP (quality 95%); the original file name is kept
- Logo watermark: use a PNG or SVG logo instead of text
- Dark mode ready: Seamless UI experience
How to Use the Tool
- Step 1: browse for your image (JPG, PNG or WebP)
- Step 2: type the watermark text, or choose a logo
- Step 3: adjust size, opacity, color and position, or enable repeat mode; the preview updates automatically
- Step 4: save as PNG, JPG or WebP
Common Use Cases
- Confidential documents: Internal reports, previews
- Copyright protection: Photos & design assets
- Client previews: Prevent unauthorized reuse
- Branding: Add your company or website name
Tips & Best Practices
- The size is a percentage of the image width, so the result looks the same on small and large images
- When a logo is loaded it replaces the text; clear the logo field to go back to text
- JPG has no transparency: transparent areas of a PNG become white
Privacy & Security
Your images are processed locally in your browser and never uploaded.
This tool is ideal for professionals, designers, photographers, and anyone who needs fast and secure watermarking without installing software.
