Content scrapers and automated AI bots harvest photography across social media and portfolio sites daily. Adding subtle, professional copyright watermarks discourages unauthorized reuse.

With ILoveImages' Watermark Image tool, you can apply custom text or PNG logo overlays across dozens of photos at once with customizable positioning, opacity, and tiling.

By utilizing modern browser WebAssembly and HTML5 Canvas pipelines, ILoveImages processes every image locally inside your device memory. This eliminates upload bottlenecks, protects your confidential files from third-party server exposure, and provides lightning-fast execution even on high-resolution camera files.
