Topaz Photo AI (formerly Topaz Gigapixel, Sharpen AI, and DeNoise AI combined) is professional desktop software for AI-powered photo enhancement. The application uses AI trained on millions of images to perform three core functions: enhance (improve overall quality), sharpen (recover detail and fix blur), and upscale (increase resolution up to 600%). Topaz is renowned in professional photography for producing the highest quality results - landscape photographers use it to maximize detail, event photographers to rescue underlit shots, and print professionals to prepare images for large formats. The AI analyzes each image individually, applying appropriate enhancement rather than generic filters. Topaz Photo AI can recover surprising amounts of detail from blurry or noisy images. The software runs locally on your computer (Windows/Mac), processing happens on-device without cloud uploads, which many professionals prefer for privacy and speed. Topaz can process RAW files and integrates as a plugin with Lightroom and Photoshop. One-time purchase with free updates for a year. Used by professional photographers, print shops, and anyone needing maximum image quality.
