Image Watermark
Add a fully customisable text watermark to any image — all processing happens in your browser, nothing is uploaded
What is Image Watermark?
An image watermark tool lets you overlay custom text or a logo onto any photo before sharing it online. Watermarking is a widely used technique among photographers, designers, content creators, and businesses to assert ownership, deter unauthorised copying, and reinforce brand identity across social media, stock libraries, and client galleries.
With full control over position, opacity, font size, colour, and rotation, you can create watermarks that are visible enough to deter theft yet subtle enough not to distract from the image itself. You can choose to place your mark in a corner, centre it, or tile it across the entire image for maximum protection.
All processing happens directly in your browser using the HTML5 Canvas API, so your original photos are never uploaded to any server. Whether you are protecting a single hero shot or batch-marking an entire portfolio, this tool gives you fast, private, professional results without any subscription or software download required.
