Add Watermark to Image

The Image Watermark tool overlays a text or logo watermark onto your photos and graphics directly in the browser, giving you a fast way to mark ownership, add branding, or discourage unauthorized reuse before you publish an image online. You can type custom text — a name, a website URL, a copyright notice — choose its font size, color, and opacity, and position it anywhere on the image, from a subtle corner mark to a bold diagonal band across the center. Photographers publishing portfolio previews, small businesses protecting product photography, freelance designers sharing draft mockups with clients, and content creators posting to social media all use watermarking for the same underlying reason: once an image is public, it can be copied, and a visible watermark makes it clear who created it and discourages casual theft. A watermark also serves as free advertising — a website URL stamped in the corner of a shared photo can drive traffic back to your site every time the image circulates. Getting the balance right matters. A watermark that's too bold ruins the image and annoys viewers; one that's too subtle is easy to crop out entirely. A common approach is to place semi-transparent text (around 30–50% opacity) in a lower corner, sized proportionally to the image so it stays legible without dominating the composition. For work you want to protect more aggressively — like preview images for paid stock photography — a larger diagonal watermark across the center makes cropping it out impractical while still letting a client evaluate the composition and quality. Keep watermark text short: a name, handle, or short URL reads clearly at small sizes, while a long sentence becomes cluttered and hard to read on smaller images. Watermarking fits naturally into a broader image-preparation workflow. You might crop a photo to the right aspect ratio first with the Image Cropper, add a watermark for protection, then compress it as WebP with the Image to WebP converter to keep page load times fast, or convert it with PNG to JPG if you need a smaller file without transparency. If the original photo contains EXIF metadata you'd rather not publish alongside your watermark — such as GPS location or device information — running it through the Image Metadata Remover beforehand is good practice for privacy. As with every tool on this site, watermarking happens entirely client-side: your image is processed using your browser's canvas capabilities and never uploaded to a server or stored anywhere. This makes it safe to use on unpublished client deliverables, pre-release product photography, or any image you need to protect before it's ready for public distribution. There's no account, no upload queue, and no waiting — you get an instantly watermarked image ready to download and share.
