About Gigapixel

Gigapixel 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 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.

Once you have opened Gigapixel on your computer, there are three options:

BUY LICENSE is the link to purchase the application.

This demo will be the same as the paid version except that you will not be able to save your images without buying the license. There is no quantity or duration limit to use the Free Demo.

Import Your Image

Import a file by dragging and dropping your file into the app or selecting "Browse Images".


Enhance Your Image

Use the Filters Panel to begin upscaling or refining your image.

These features are located on the right side of the screen.


There are five main sections that you can use:

  • Resize mode - upscale and crop your image
  • AI model - boost the overall image quality
  • Settings - denoise or sharpen your image
  • Face recovery - improve and refine faces
  • Gamma correction - reduce color bleed

Export Your Image

Click ‘Export image’ under the Filters panel.


An Export Settings window opens.


Use the settings to customize your exported images.



Add a custom prefix and suffix. Gigapixel has the default suffix "-gigapixel" when you first open the application.

There is a toggle option to include any filters you used that is added at the end.



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

  • Desktop - your computer's main desktop
  • Original Folder - the folder where you imported your original image
  • Browse - a custom folder that you can search for


Save your new enhanced image as a different file type.


The dropdown menu has four 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


Preserve or change the color space of your export file. Color space helps define the range of colors that a device or file can reproduce. Changing the color space of the output file may also be affected depending on your monitor’s calibration.

Choose from several common options in the dropdown menu. If you are unsure which one to use, select “Preserve input color space” to maintain the same color space that was used in the original input file.


There are seven options to choose from:

  • Preserve input color space - Maintain the same color space as your original file
  • ProPhoto - best used for images printed on digital and/or inkjet printers
  • sRGB IEC61966-2-1 black scaled - for scanners, low-end printers, or photos going onto the web
  • Adobe RGB (1998) - for images printed with a CMYK printer
  • Apple RGB - for working with older MAC OS displays or legacy desktop publishing files
  • Wide Gamut - often associated for using with 4K Resolution displays
  • CMYK U.S. Web Coated (SWOP) v2 - used for web offset publications
