About 水印制作器
OptiPix Watermark Maker lets you add customizable text or image watermarks to your photos to protect your creative work. Add your name, brand, copyright notice, or logo to images before sharing them publicly. The tool offers full control over watermark appearance: adjust text, font size, color, opacity, rotation angle, and position. You can place watermarks in corners, centered, or as a repeating tiled pattern across the entire image for maximum protection. For image watermarks, upload your logo or graphic and position it with adjustable opacity and size. All processing happens locally in your browser — your original photos and watermark assets remain completely private. Batch watermarking is supported, letting you apply the same watermark to multiple images at once. The tool outputs high-quality JPEG or PNG files with the watermark permanently embedded in the pixel data.
How It Works
The tool draws your image onto a Canvas element, then overlays the watermark text or image at your specified position, size, opacity, and rotation. The composite result is re-encoded as a new image with the watermark permanently embedded in the pixel data.
