Part 1: Upscale Image in GIMP with Enhance Tools

GIMPs Image Enhance Tools are a collection of features designed to improve the quality of photos and graphics. These tools include options for adjusting brightness and contrast, sharpening images, reducing noise, correcting colors, and enhancing details. With these tools, users can make their images look more vibrant and professional, even if they have little to no experience with photo editing. GIMP's intuitive interface and powerful enhancement capabilities make it a popular choice for both beginners and advanced users.

Step 1

Open GIMP and choose your file by choosing File > Open to open the image you want to enlarge.

Step 2

Select Image > Scale Image from the menu. This opens a dialog window where you can change the dimensions of your image. Make sure the chain link icon between the width and height boxes is connected in order to maintain the aspect ratio.

Step 3

In the Scale Image dialog, you'll find an Interpolation dropdown menu. Select NoHalo or LoHalo for better-quality results. These methods are designed to minimize the artifacts that can occur when upscaling images.

Step 4

Click the Scale button to apply the new dimensions to your image.

Using GIMP built-in tools is a straightforward method for upscaling images, especially for minor adjustments. It also has other powerful photo editing tools like removing watermarks, erasing backgrounds, and more.

However, it may not always provide the best results for significant upscaling. For better results, ensure you choose an appropriate interpolation method and consider making additional manual enhancements to sharpen and refine the image.

Part 2: Upscale Image in GIMP with AI Upscale Plugin

Upscaling an image in GIMP with the AI Upscale Plugin involves using artificial intelligence to increase the resolution and quality of an image. For more advanced upscaling, GIMP can be enhanced with plugins like Stable Boy, which uses AI technology to improve image resolution and quality. Similar to Stable Diffusion upscaling images, with the use of artificial intelligence (AI), this GIMP plug-in can successfully enlarge photographs without causing pixelation or blurriness, which is perfect for photographers, graphic designers, and anybody else wishing to increase image quality.

Step 1

Download the Stable Boy plugin from the official website or a trusted source. Follow the installation instructions, which typically involve placing the plugin file in the GIMPs plugin directory and restarting the application.

Step 2

Launch GIMP and open the image you want to upscale.

Step 3

Go to Filters > Enhance > Stable Boy. This will open the plugin's interface.

Step 4

Adjust the upscaling parameters as needed. Stable Boy offers various options for increasing resolution and improving quality.

Step 5

Click the OK button to start the upscaling process. The AI algorithm will analyze and enhance your image, providing a high-quality result.

Using the Stable Boy plugin in GIMP leverages AI technology to achieve superior upscaling results. This method is particularly useful for significant resolution increases and for images that require high detail. Ensure you experiment with the settings to find the optimal configuration for your specific image. However, if you are a beginner, then this may be a little hard to start.
