8 Best AI Image Upscaler Tools in 2024 (Free and Paid)

After the recent AI boom, images have seen the biggest advancements and improvements in our digital lives. You can create some spectacular AI images using Midjourney or use Photoshop’s AI Generative Fill to manipulate photos in ways that were never possible before. In addition to that, you can now upscale existing images to 4K or 8K resolution with the magic of AI. You can restore details, make images unblurry, fix pixelated photos, and much more. So without any wait, let’s go through the list of best AI image upscaler tools.

1. Image Scaler by Stability AI

The popular creator behind Midjourney alternative Stable Diffusion, Stability AI, has an AI image upscaler tool too, and it works wonders. I have personally used the AI tool many times in the past, and I can say that it’s easier to use and does a fantastic job at upscaling images without sharpening the image too much.

The best part of Stability AI’s image upscaler is that it’s free to use for 2x image upscaling. If you want upscale images 4x to 16x, you need to subscribe to the paid plan.

The paid plan also brings access to a faster Stable Diffusion XL model for AI image generation, relighting, text remover from images, and much more. In case, you want to upscale images while also adding details to the image, you can do that with this tool.

However, it’s also available to paid users only. Nevertheless, the free tool is good enough for most users, and I think you should definitely check it out.

2. SuperImage

Unlike online AI image upscaler tools, SuperImage is a fantastic app that allows you to upscale an image locally on your device, and that too without an internet connection. This is an amazing app for users who are paranoid about their privacy and don’t want to upload personal photos on online services.

It can seamlessly sharpen any low-res image up to 16x without any charge. The app is free to use. However, if you want to use custom upscaling models, you can install its paid SuperImage Pro app. The app uses a neural network with a deep learning framework along with a Real-ESRGAN algorithm to upscale your image. It uses your device’s GPU to restore the details of the image.

SuperImage is available on Android and Windows for now, but the developer says it’s also coming to macOS and Linux very soon. So, I would say, if you have a flagship Android phone or a powerful PC, go ahead and try this tool.
