Free Online Image Watermark Tool
Protecting your visual content online requires visible ownership markers. Whether you are a photographer sharing portfolio samples, a designer posting mockups, or a business branding marketing assets, watermarks deter unauthorized use and reinforce your identity. Our free image watermark tool adds text or logo overlays directly in your browser.
Upload an image, configure your watermark text or logo, adjust position, opacity, and size, then download the watermarked result. No Photoshop required, and your originals never leave your device.
How to Use the Watermark Image
Upload the image you want to watermark. Choose text watermark and enter your name, URL, or copyright notice — or upload a logo image as an overlay. Adjust position (center, corner, tiled), opacity, font size, and color. Preview the result in real time. Download the watermarked image when you are satisfied with the placement and appearance.
Why Watermark Image Matters
Image theft is rampant on social media and stock photo sites. A visible watermark reduces unauthorized commercial use and helps viewers find the original creator. For businesses, watermarks reinforce brand consistency across marketing channels. Photographers sharing proofs use watermarks to protect work before client payment.

- Graphic designers brand mockups and concept work shared for client review.

Tips for Getting the Most From This Tool
Place watermarks where they are visible but do not destroy the image — a semi-transparent corner mark works well. For portfolio protection, use a diagonal tiled watermark at 20–30% opacity. Include your website URL in text watermarks so interested viewers can find you.
Frequently Asked Questions
Can I use my logo as a watermark?
Yes. Upload a PNG logo with transparency and position it anywhere on the image with adjustable opacity.
Will the watermark be removable?
Any visible watermark can be partially removed by determined users. Watermarks deter casual theft and assert ownership, not provide cryptographic protection.
Are my images uploaded to a server?
No. Watermarking runs entirely in your browser using the Canvas API.
What opacity should I use?
20–40% opacity is typical for corner watermarks. Increase opacity for tiled patterns that cover the entire image on proofs.
