GIMP is a free and powerful web-based photo editing software that comes with a huge number of features. Our favorite feature, like photo upscaling, is also available. You can increase your image size in different dimensions, which GIMP offers to you. It uses different algorithms to fill in the missing information in your image.

Image Enhancing Feature

To use this feature, ensure that you are using the latest version. To use this feature, follow the instructions:

Add the low-resolution picture file to GIMP.

Go to the Image menu

Choose the Scale Image

Put your desired dimension in the Widht and Hight Fields

Under Interpolation, choose Lanczos

Click on Scale image to enhance your image

Increase the quality of the Image

After the upper process, you can apply the gentle sharpening effect to add more details to your image. You have several tools under the Enhance section to upscale your image. For instance, you can use the sharpening tool to sharpen. To get a high-quality image, use PNG format and avoid JPEG.

Increase Image Resolution with Resynthesizer Plugin

If you have complex images and aren’t enhancing with these processes then you can try the Resynthesizer plug-in that is available on their official plug-in repository. To upscale your image with Resynthesizer, follow the guide:

Open GIMP and load your picture to it

Click the Filters menu

locate Enhance from its drop-down list

then choose Resynthesizer

In the Synthesis method

Select the Auto-detect or experiment with other options, such as Texture synthesis

Adjust the Synthesis scale slider for the desired level of resolution.

These methods examine the image’s surface and ways to recreate it in the upscale area. Adjust the settings like Search Size and Blend Mode for fine-adjusting the result. You can preview the upscaled picture. Behind that, click the Synthesize button to do your operation.

Use these methods for your different images and upscale them easily.
