SuperWatermark Pro

SuperWatermark is a professional image watermarking tool that lets you easily add text watermarks, image watermarks, and timestamp watermarks to your photos. It supports both single-image and batch processing, allowing you to apply a uniform watermark to multiple photos at once and significantly boost your productivity. With 6 position options (top-left, top-right, bottom-left, bottom-right, center, tiled), you can freely adjust font size, opacity, rotation angle, and color, and preview before saving. All features run completely offline: your photos and watermarks are stored only on your device and are never uploaded to any server, so your privacy is fully protected. Great for e-commerce product images, photography copyright protection, design markup, work documentation, social media publishing, and much more.
