Topaz Gigapixel is an AI-powered desktop app for increasing image resolution without the usual loss of quality.
What it does
Gigapixel analyzes the original photo and generates new detail to produce a sharper, more natural-looking upscale—useful when you need larger images for print, cropping, or restoring older shots.
Key features
Upscale images up to 600%
Recover fine details (skin texture, fabric, feathers, hair)
Batch process multiple images at once
Sharpening tools to improve clarity
Noise reduction, especially for high-ISO photos
Supports common formats including RAW, JPEG, and TIFF
How to use
Download from the official website and install
Open the app and import an image (browse or drag and drop)
Choose an upscale level (2x, 4x, 6x) and an AI model suited to the image type
Process and save the result to your computer
Topaz Gigapixel is available for Windows and macOS, and can also be used as a plugin for Adobe Photoshop and Lightroom. It is not available for free; a purchase is required for unlimited use.
