Protect your digital assets with ease
Watermarking your images is one of the most effective ways to prevent unauthorized use and content theft. Whether you’re a designer, photographer, or online store owner, adding a visible watermark reinforces your ownership and ensures brand recognition across platforms. This tool allows you to add professional-looking watermarks in seconds—no software, no registration, just full control right in your browser.
Add text or logo watermarks, or both
Choose from two watermarking options: custom text or an uploaded logo image—or combine both for enhanced branding. Each watermark layer can be resized, repositioned, rotated, and adjusted for opacity. You can even tile the watermark across the image for stronger protection. Whether you're placing a single signature or overlaying a logo grid, every element is customizable to match your style.
Watermark multiple images in one go
Need to watermark a whole set of images at once? Our batch watermark feature lets you apply the same configuration across all files instantly. Edit one image, then use the sync brush to copy those settings to every other image. Combined with one-click batch download, this saves time for creators who handle dozens—or even hundreds—of visual assets daily.
Customize fonts, colors, positions, and more
Fine-tune your watermark to match your brand or aesthetic. Adjust font family, font size, color, transparency, rotation angle, and placement—all in real time. This level of customization makes it easy to create subtle, elegant marks or bold branding overlays. Whether you want to watermark for copyright protection, visual signature, or promotional value, you have full design freedom.
Why watermarking matters more than ever
In a digital world where images are shared, copied, and repurposed across platforms within seconds, protecting your content is critical. A visible watermark serves as a simple yet powerful deterrent against unauthorized use. For photographers, content creators, bloggers, marketers, and businesses alike, watermarks reinforce ownership and help establish brand recognition. Unlike metadata, which can be stripped, a watermark remains visible and attached to the image. Whether you're uploading to social media, sending previews to clients, or showcasing work in a portfolio, watermarking provides peace of mind. It's not just about protection—it's about credibility, professionalism, and control. And when the watermark is thoughtfully placed and well-designed, it can even enhance the visual impact of your content. This tool helps you watermark images quickly and reliably, so you can focus on creating without constantly worrying about misuse.
Text, logo, or both: complete watermark control
Everyone has different watermarking needs. Sometimes a simple text overlay is enough to communicate ownership. Other times, you want your official logo embedded in your photos for maximum brand visibility. This image watermark tool gives you the freedom to choose—use either or both. Add your name, brand message, or copyright notice with full control over font, size, rotation, color, opacity, and position. Upload your own logo image and place it exactly where you need it. You can even tile either watermark type across the entire image surface. With both text and logo watermarks available, you have everything you need to build a personalized and consistent watermarking style that aligns with your visual identity. Whether it’s one image or one hundred, your watermark will look sharp and professional every time.
Batch watermarking made easy and efficient
Watermarking dozens of images one by one can be tedious and time-consuming—but not with this tool. The batch watermark feature is designed to help you apply the same watermark configuration across multiple images instantly. After customizing your first image, the sync brush allows you to copy your settings—position, size, font, rotation, opacity, and more—to all remaining images in a single click. No need to repeat the same steps manually. Combined with the batch download button, you can preview and export every watermarked image with minimal effort. This is perfect for e-commerce sellers, social media managers, real estate agents, or anyone who regularly works with high volumes of images. If you need to watermark a product catalog, a photoshoot set, or a portfolio, this tool is built for speed, accuracy, and scalability.
A fast and flexible watermarking experience
What sets this tool apart is its smooth, responsive, and fully browser-based interface. There’s nothing to install, and no need to sign up—just open the page, upload your images, and start watermarking. Every change you make is reflected instantly, so you can fine-tune your watermark in real time. Whether you’re adjusting text or logo settings, resizing, rotating, or tiling, the live preview helps you get it right before export. The interface supports drag-and-drop uploads, high-resolution images, and smart rendering performance. Even when working with large image sets, the editor remains fast and fluid. Best of all, the tool respects your privacy—no data is sent to external servers unless you choose to export. Everything happens right in your browser, keeping your files safe and your workflow distraction-free. It’s watermarking made effortless, for everyone from beginners to professionals.
