After the recent AI boom, images have seen the biggest advancements and improvements in our digital lives. While you can modify images using AI photo editors, to upscale existing images to 4K or 8K resolution, you can use dedicated AI image upscaler tools. You can restore lost details, make images unblurry, fix pixelated photos, and do much more with AI image upscalers. So without any wait, let’s explore the list.
1. Upscayl
Upscayl is a free and open-source program that can upscale your images in no time. It’s available on Windows, macOS, and Linux, and the developer is planning to bring its AI image scaler tool to the cloud too. Currently, the cloud service is in beta. However, you can run it on your computer locally and upscale low-resolution images into high-resolution images. It offers five different modes to choose from and uses your GPU to sharpen blurry images.
The best part is that you can batch upscale images with this program which is not available on other free tools. The tool supports PNG, JPG, and WEBP image formats and supports models like Real-ESGRAN, REMACRI, and more. In my testing, I liked the no-nonsense UI, and Upscayl quickly restored the image details using AI.
Platforms: Windows, macOS, and Linux
Price: Free
Upscale.media is one of the best AI image upscaler tools you can use on the web. Simply open the website, upload your photo, and download the upscaled image. No need to sign up, add your credit card, or subscribe to any paid plan. It’s that effortless.
The best thing about upscale.media is that you can upscale up to 4x resolution for free. Generally, free websites have limited options up to 2x. Moreover, this upscaler is available as Android and iOS apps.
Upscale.media supports popular image formats, including PNG, JPEG, JPG, and WEBP. Having said that, your photos will be uploaded to the cloud for AI image processing so keep that in mind, Overall, it’s an effortless solution for turning low-quality images into highly-detailed photos.
Platform: Web, Android, and iOS
Price: Free, Paid plan costs $29 for 300 credits
3. 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.
Platforms: Android, and Windows
Price: Free (with ads)
4. Topaz Gigapixel
Gigapixel AI by Topaz Labs is a powerful AI image upscaler that comes at a price. If you are a photographer or a video creator, Gigapixel AI should be your first choice as it can also upscale your videos. It’s used by corporations like Netflix, Warner Bros, Disney, Apple, and more.
Gigapixel AI uses deep learning to restore video footages and enhances the detail in a customized way, which other services don’t provide.
The models are continuously trained on a large variety of images to understand the scenes and fill in the pixels to give a natural look. So be it portraits, wildlife photos, landscapes, or architecture, Gigapixel AI can be the best AI image enhancer for you.
With all that said, the program is not free, and you’ll need to pay $99.99 to use the AI tool. For free users, it lets you access the program under a free trial.
Platforms: Windows and macOS
Price: Free trial, after which it costs $99.99
5. Pixelcut
Pixelcut is a popular app for AI image editing on Android and iOS, but most of the features are paid-only. However, on the web version of Pixelcut, you can upscale images for free, and it’s pretty good. You don’t have to sign up and create an account. Simply upload your image and upscale images up to 2x resolution for free.
If you want to upscale images up to 4x, you will have to pay for the Pro plan. In my testing, Pixelcut did a decent job, and increased the resolution, but couldn’t add more details. By the way, there is a Midjourney Upscaler as well if you want to improve the quality of AI images generated using Midjourney. And you can also upscale logos using the dedicated tool.
Platforms: Web, Android, and iOS
Price: Free, Paid plan starts at $4.99 per month
6. OpenModelDB
OpenModelDB is not for everyone, but if you are a technical user, you can use this platform to find the best AI upscaling models. It’s a community-driven repository where hundreds of dedicated AI models are available for image upscaling. If you want to upscale cartoon images, Anime images, video frames, game textures, Manga, Pixel art, etc., you can find the suitable model for your use-case here.
To run these custom AI upscaling models, you will have to use another program such as ChaiNNer, Upscayl, ComfyUI, or Topaz Gigapixel. Of course, you will need a slightly capable computer with decent hardware to run these models locally. So go ahead and check out OpenModelDB to find image upscaling models tailored to your specific image type.

7. Image Scaler by Jasper
The AI image upscaler by Jasper 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. Jasper has created a great AI image-editing platform called Clipdrop where you can access many such tools.
The best part of this 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 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 too on Clipdrop. Put simply, the free tool is good enough for most users, and I think you should definitely check it out for image upscaling.
Platforms: Web
Price: Free, Paid plan starts at $10 for 1000 credits
8. Remini
Remini is another fantastic app to upscale images using AI on Android and iPhone. Not just that, it can restore old memories, recover lost details, fix pixelated and grainy images, and much more. However, it’s not entirely free to use. You need to watch a 30-second ad to upscale an image and another ad to save the restored photo. In addition, your image will be uploaded to the cloud for processing so there is that.
That said, Remini works much better for human faces and selfies. It also has other features such as the ability to create 90s yearbook photos, professional resume shots, AI image generation, face beautifier, and more.
So if you use an iPhone or Android phone and want to use a brilliant AI image upscaler, Remini is the way to go. In addition, you can also try Pixelup (iOS) and AI Enlarger (iOS) on your iPhone.
Platforms: Web, Android, and iOS
Price: Free, paid plan starts at $6.99 per week
9. Let’s Enhance
Let’s Enhance is another free AI upscaler that I liked for its simplicity and ease of use. All you need to do is sign up for an account, and you can start upscaling images using AI. It also supports batch upscaling, which is good to have in a free service.
Along with that, you will get support for image lighting, tone enhancement, color enhancement, and background removal — all powered by AI. In my testing, its upscaled images were on par with other service providers.
However, under the free tier, it only does 2x upscaling so you will have to make peace with that. Apart from that, free users only get 10 credits, and you will have to pay $9 per month for 100 more credits. It also unlocks larger resolutions and a plethora of new features.
If you’re looking for a tried-and-tested online service for AI photo enhancement, go ahead and try Let’s Enhance.
Platforms: Web
Price: Free up to 10 credits, Paid plans start at $9 for 100 credits
10. Img Upscaler
Img Upscaler is our final tool on this list that lets you upscale images up to 4x resolution for free. You can upload PNG and JPG photos and get them upscaled in no time. The online tool also offers batch upscaling and larger resolution, but it’s only available to paid users, starting at $19 per year. You will get 100 credits per month under this plan, which is decent.
According to the service, all your photos are uploaded to the cloud, but they are removed within 24 hours. For anime, cartoons, and even facial photos, Img Upscaler is a decent service and you should give it a try.
