Free Online Image Watermark Tool - Add Professional Text or Logo Watermarks
Watermarking is the fastest and most effective way to protect your copyright and brand your images. This tool lets you add both text watermarks (with customizable font, style, color and shadow) and image/logo watermarks, placed in any of 9 positions or tiled across the entire image to deter copying. Every change appears instantly in the live preview, and all processing happens right inside your browser — your images never leave your device.
How to Use
Drag and drop an image into the upload area, click to pick one from your device, or paste directly from the clipboard with Ctrl+V. JPG, PNG and WebP are supported.
For text watermarks: type your content, then set the font, bold/italic, color and shadow. For image watermarks: drag and drop your logo and adjust its scale.
Pick one of 9 positions or enable Repeat for full coverage. Fine-tune opacity, rotation and padding — results update instantly in the live preview.
Select PNG, JPG or WebP, adjust the quality slider if needed, then click Download to save your image at full original resolution.
Key Features
Choose from 6 popular fonts, toggle bold/italic, pick any color and add a shadow so your text stays readable on any background.
Drag and drop a transparent PNG logo or signature as your watermark, then scale it from 10% to 200% to fit your photo perfectly.
Place your watermark in any corner, edge or the center with a single click using the intuitive 3×3 position grid.
Enable Repeat to spread the watermark across the whole image — covering every corner even when rotated, for comprehensive protection against cropping.
Adjust opacity from 10–100%, rotate freely from 0–360° and tweak padding so the watermark blends naturally into your composition.
The preview updates instantly with every change and is optimized to stay smooth even with high-resolution images.
Download as PNG, JPG or WebP, with a quality slider for JPG/WebP to balance file size against sharpness.
All processing runs right in your browser. Nothing is uploaded or stored — your images always stay on your device.

Frequently Asked Questions
Are my images stored anywhere?
No. The tool applies watermarks entirely in your browser (client-side) using Canvas. No image is ever uploaded to a server — your data always stays on your device.
Can I use my own logo as a watermark?
Yes. Switch to the 'Image Watermark' tab, drag and drop or select your logo file (a transparent PNG works best), then adjust its scale, position and opacity as you like.
Does watermarking reduce the original image quality?
No. The downloaded image is rendered at full original resolution. The preview is only downscaled for smooth display and does not affect the final file. With PNG, quality is preserved exactly.
Which format should I choose: PNG, JPG or WebP?
Choose PNG for the highest quality or to keep transparency. Choose JPG for a smaller file (the image will get a white background). Choose WebP for web optimization. For JPG and WebP you can use the quality slider to balance size and sharpness.
How do I make the watermark readable on light or dark backgrounds?
Pick a text color that contrasts with the background (white on dark images, black on light ones) and enable the 'Text Shadow' option to make it stand out. An opacity of around 30–50% usually looks natural and professional.
Can I cover the entire image to prevent copying?
Yes. Turn on the 'Repeat Watermark' switch to tile the watermark across the whole image. Combine it with rotation (e.g. 30–45°) to create a diagonal, full-cover protective layer that's hard to crop out.
