Free Online Image Watermark Tool
Sharing photos or graphics online often means they can be copied without credit. Adding a watermark - your name, a copyright notice, a website URL, or "draft" - is a simple way to mark your work as yours and discourage unauthorized use. LovePDFImg's Image Watermark tool lets you add custom text to any image with full control over position, size, color, and transparency, and shows a live preview as you adjust each setting.
The watermark is drawn directly onto your image using the Canvas API, so the result is a single flattened image - no separate layers, no extra software. Position it in a corner for a subtle mark, or place it diagonally across the center for stronger protection. Once you're happy with the preview, download the watermarked image in its original format. Everything happens locally in your browser; your image is never uploaded.
Watermarking is a common step before posting photography portfolios online, sharing product photos publicly, distributing draft or sample versions of design work, or protecting original graphics shared on social media.

Why Choose LovePDFImg to Add Image Watermarks?
iLoveIMG and similar tools offer watermarking, typically via server upload and sometimes with limited customization. LovePDFImg applies the watermark entirely in your browser using the Canvas API with a live preview, so your image never leaves your device. There's no account requirement, no daily cap on usage, and - unlike some "free" tools - we don't add our own branding on top of your chosen watermark.
Technical Details
Adding a watermark draws your text directly onto the image canvas at the chosen position, size, color, and opacity, then flattens the result into a single new image. Because the watermark becomes part of the pixel data itself, it can't be separated back out - this is intentional, since a removable watermark provides little real protection. For JPG output, the tool uses a high quality export setting to keep the underlying image free of visible compression artifacts.
