Rifat Business Apr 19, 2024

AI image upscalers, such as Gigapixel, make your photos bigger easily. They're fast, reliable, and keep your photos looking natural. It's better than editing in Photoshop or Lightroom. We'll talk about one AI upscaler, show you how to use it, and its settings. Let's get started!

What is Image Upscalling?

Image upscaling is the process of enlarging a digital image while maintaining its quality and clarity. It uses algorithms to add more pixels to the image, resulting in a higher resolution without significant loss of detail. This technique is commonly used to enhance the size of images for various purposes such as printing, viewing on high-resolution displays, or improving the visual appeal of photographs.

AI Model For Image Upscalling

Gigapixel's AI models are different from each other. They're made for specific types of photos, so it's important to pick the right one for what you need. But it's best to try a few models before deciding on one. Even though Gigapixel suggests certain models for certain photos, your result might be different.

For instance, let's say you took a photo with an iPhone 11 using a 12MP lens. When you used the Standard V2 AI model along with automatic adjustments for noise, blur, compression, and face recovery, the photo turned out much sharper with more detail. Here's a quick look at each AI model so you know which one to use in different situations:

Standard V1 & V2

This picture was clicked using an iPhone 6, which has an 8MP camera. Gigapixel selected the Standard V2 model using automatic AI mode. The settings were:

  • Minor Denoise at 40,
  • Minor Deblur at 35,
  • Fix Compression at 7,
  • Face Recovery with a strength of 82

Also, Gamma Correction was enabled. Standard V1 and V2 models have an additional setting called Fix Compression. The AI checks the photo and decides what adjustments are necessary. Options differ based on the AI model selected.

High Fidelity

When you're dealing with big image files from new smartphones, you might not see much improvement. But that's where Gigapixel comes in. Take, for example, a photo from an iPhone 15 Pro Max with a 48MP camera. We bumped up the resolution from 4284 x 5712 px to 17136 x 22848 px without losing quality. We used the High-Quality V2 AI model with these settings:

  • Minor Denoise: 76,
  • Minor Deblur: 38,
  • Fix Compression: 34,
  • Face Recovery: strength of 100,
  • Gamma Correction: Enabled.

Art / CG

We tested an Art/CG AI model by creating an image using Jasper Art. The original photo size was 512 x 512 pixels. Then, we used the AI model to make it four times bigger, resulting in a 2048 x 2048 pixels image. We adjusted some settings like

  • Minor Denoise: 13
  • Minor Deblur: 43
  • Face Recovery: strength of 75
  • Gamma Correction: Enabled

Comparing the original AI-generated image with our upscaled one showed interesting differences. The AI reduced blur and improved the fur detail on the cat.

Low Resolution

We took a Facebook cover photo that was 960 x 720 pixels. Then, we used an AI tool to make it bigger, turning it into 3840 x 2880 pixels. Here are the settings we used:

  • A little less noise: 17
  • Some blur reduction: 81
  • Enhanced face details: 80
  • Gamma Correction: On

The AI made the image look better, adding more details to things like trees and the sky.


We tried the new Lines AI model in Gigapixel version 7. It's great for architectural photos or ones with text. We used it on a photo from a recent trip to France with these settings:

  • Minor Denoise: 15
  • Minor Deblur: 35
  • Face Recovery: Disabled
  • Gamma Correction: Disabled

The result was impressive. Gigapixel AI sharpened the image and enhanced the details of the statues on the roof. We increased the resolution from 1200 x 1600 px to 7200 x 9600 px and improved the overall quality.

Very Compressed

The latest AI model in Gigapixel AI is called Very Compressed. It's great for fixing photos with lots of compression or flaws, like old or scanned pictures. We tried it on a social media image that had been resized many times, using these settings:

  • Minor Denoise: 67
  • Minor Deblur: 41
  • Face Recovery: 80
  • Gamma Correction: Enabled

The changes aren't dramatic, but we managed to make the image four times bigger without losing much detail.

Limitation Of AI Image Upscaling Tools

Using AI to make images bigger can make them better by making them clearer and more detailed. But, there are some things to think about. First, when you make a picture more than twice as big, it might not look as good. It could be less clear and sharp.

Also, sometimes the picture might look too perfect, not real. It depends on the tool you use. Lastly, if a picture is already bad quality, AI can't fix it completely. So, choose pictures with some detail for the best results.
