An open-source alternative to Photoshop, GIMP is a popular photo manipulation software that you need to download on your computer. This tool offers a plethora of features like resizing and converting the image in different formats. Yes, it literally does much more than just increasing the resolution of images. 

Main Features

  • Many resizing formats for you to choose from
  • You can resize photos with a single click
  • Provides a customizable desktop interface for complete manipulation of images
  • Allows enhancing of images and digitally retouching them for printing
  • Selection of several interpolation methods for enlarging images
  • Available in multiple languages


GIMP is a completely free software for photo editing and resizing. 

Test results

After conducting the tests on the two images, it was observed that selecting “None” for the quality interpolation yielded the best results. Nonetheless, it depends on the size of the images so you can try choosing other quality interpolation methods and see the results for yourself. 

There seemed to be an inconsistency with the resizer because the resulting image sizes did not correlate with the dimensions. 

Anyway, the test results for Image 1 were brilliant as the image detail was retained with minor color changes and some added depth to it.

With Image 2 however, GIMP significantly struggled. This indicates that you cannot use GIMP for enlarging images that have a significantly small size.

Results for Image 1:

  • Increased 2x
  • 1200 x 800 px
  • 650 KB

Results for Image 2:

  • Increased 2x
  • 600 x 400 px
  • 249 KB

Final Verdict: Which Tool is the Best?

After testing out these five great tools to enlarge images and checking the quality of the resulting images, it is recommended to try Upscale Pics first. If your requirement gets compensated with this one only, there is no need to go for others mentioned above. But in case, you find ReShade or On1 Resize or another one from this list as the perfect fit, go for the same.

The reason behind this advice is that all of them work differently in image resizing. Some of them work better with animation or vector-style graphics, whereas others may work better with detailed landscape images but not that great with animations. Thus, it depends on the type of images you will need to resize frequently. That’s all!
