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.
