Image Watermark
Add text or image watermark to photos online free. Adjust position, opacity, size, font and tiling. Protect your images with custom watermarks instantly.
What is an image watermark and why use one?
An image watermark is a visible overlay — text or logo — placed on a photo to identify ownership, protect copyright, or brand content. It deters unauthorized use and helps promote your work across social media and websites.
How do I add a text watermark to a photo?
Upload your image, type the watermark text, then customize the font, size, color, position and opacity. Preview the result in real time and download the watermarked image with one click.
Can I use my logo as a watermark?
Yes. Upload a PNG image with transparent background as your watermark. This is ideal for brand logos, signature stamps and custom graphics that need to appear on multiple photos.
What image formats are supported?
The tool supports PNG, JPEG, WebP, BMP and GIF as input. Watermarked images are exported as PNG to preserve maximum quality and support transparency.
Are my photos uploaded to a server?
No. All image processing happens locally in your browser using the HTML5 Canvas API. Your photos never leave your device, ensuring complete privacy and security.
Can I repeat the watermark across the entire image?
Yes. Enable the tiling option to repeat the watermark in a diagonal or custom angle pattern across the whole image. This is the most effective method for copyright protection.
How do I adjust watermark opacity?
Use the opacity slider to make the watermark more or less transparent. A lower opacity makes the watermark subtle and less intrusive, while higher opacity makes it more prominent and harder to remove.
Can I change the watermark position?
Absolutely. Drag the watermark to any position on the image, or use preset positions like center, corners, or edges. You can also fine-tune the exact placement with pixel precision.
Is this watermark tool free to use?
Yes, completely free with no registration required. There are no watermarks on the watermarks — no limits on the number of images you can process or the output quality.
Does the tool work on mobile devices?
Yes. The tool is fully responsive and works on smartphones, tablets and desktop browsers. Touch gestures are supported for positioning the watermark on mobile devices.
How to Use Image Watermark
Add a text or image watermark to your photos right in the browser. Nothing is uploaded — all processing happens locally on your device.
- Select the Text tab for a caption or the Image tab to place your logo.
- For text: type your Watermark Text, then pick Font, Size and Color to style it.
- Choose a Position such as Bottom Right or Center, and set Rotation (°) for a slanted look.
- Lower the Opacity, adjust Scale for image watermarks and set Spacing for a tiled pattern.
- Pick the output Format — PNG, JPEG or WebP — and the Quality, then download your protected image.
An opacity around 30-50% with a tiled layout is usually enough to deter theft without ruining the photo.
