Protect your photography from copyright theft. Add custom text watermarks and transparent logo overlays to batches of photos in seconds.
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.

Câu hỏi thường gặp
Can I tile my watermark across the entire photo?
Yes, the repeating tile pattern feature covers the entire surface to deter crop-based theft.
Can I use these tools completely offline without an internet connection?
Yes! Once you visit ILoveImages or install it as a PWA, all core scripts and WebAssembly modules are cached locally in your browser's service worker, allowing you to edit photos anywhere, even in airplane mode.
Are my uploaded photos or edits stored on any server?
Never. ILoveImages is built with a zero-server-upload architecture. Every pixel calculation occurs strictly in your browser's local sandbox memory.
