Pixel-Level Lossless Restoration: Instead of using destructive cropping or blurring, this tool utilizes an Alpha Map algorithm to accurately reverse-calculate and restore the original pixels covered by the watermark.
Efficient Batch Processing: Drag and drop dozens of images at once and download all restored results with a single click.
100% Privacy & Security: Operates entirely within your browser's front-end (HTML5 Canvas). Your images are never uploaded to any server and can be processed even without an internet connection.
