About Gigapixel AI

Gigapixel AI is a desktop software computer application for upscaling your photos, graphics, and artwork by up to 6x it’s original image size while still maintaining image quality.

The app has AI models and features that recognize and identify areas where image enhancement is recommended. It is designed to give all creatives the capability of making minor, quick fix adjustments efficiently.


Your computer must have an internet connection to install, activate, and update, but using Gigapixel AI does not require it.

Our model files are double-zipped to safeguard proprietary data, which may trigger alerts from certain security applications. We recommend you temporarily disable antivirus, firewall, VPN, or proxy before installation, as they can occasionally impede model file downloads.

The dropdown menu gives you the option to save in two locations:

  1. Original Folder - the folder where you imported your original image
  2. Browse - a custom folder that you can search for


Save your new enhanced image as a different file type.


The dropdown menu has five different options:

  • Preserve Input Format - the same file type of your original image. For example, you imported a .jpg, this will save your enhanced image as a .jpg.
  • JPEG - Common standard file type used and accepted across all computers, web browsers, and social media
  • PNG - Most preferred for saving graphics or raster image files. Best for graphics that have transparent backgrounds
  • TIFF - Best used for handling large files to store graphics and image information
  • DNG - Converts RAW files to edit easily
