Free Image Watermark Tool Online
Add customizable text watermarks to your photos. Browser-based, no upload needed.
Free image watermark tool online — add custom text watermarks to your photos instantly in your browser. No uploads, no account, and no ToolzGo branding added to your image. This free online watermark tool lets you choose the watermark text, font size, color, opacity, and position (top-left, top-right, bottom-left, bottom-right, or center). Adding a watermark protects your intellectual property, brands your images for social media, and prevents unauthorized use of your photography. Bloggers, photographers, designers, and content creators use watermarks to establish ownership before sharing images online. The watermark is applied using the Canvas API directly in your browser — your original image is never uploaded anywhere. Download the watermarked image as a PNG instantly.
