Upscayl lets you enlarge and enhance low-resolution images using advanced AI algorithms. Enlarge images without losing quality. It's almost like magic! 🎩🪄
Upscayl is a cross-platform application built with the Linux-first philosophy. This means that Linux users receive pre-release builds earlier, but Upscayl itself is available on all major desktop operating systems :)
Important
You'll need a Vulkan-compatible GPU to upscale images. Many CPUs and iGPUs do not work, but there’s no harm in trying.
Upscayl should be available in the software listings of most Linux operating systems. Your distro's Store app might also support the Flatpak or Snap version.
- Go to the releases section.
- Download the
upscayl-x.x.x-linux.AppImagefile. - Right-click AppImage -> Go to the Permissions tab -> Check 'allow file to execute' and then double-click the file to run Upscayl.
You can also choose to install using other formats like RPM (Fedora), DEB (Debian/Ubuntu-based), and ZIP (any Linux OS).
- Go to the releases section.
- Download the
upscayl-x.x.x-mac.dmgfile. - Double-click dmg and drag the Upscayl icon into the Applications folder.
- Open Finder and click the 'Applications' tab in the left sidebar. Find Upscayl and right-click on it. Select 'Open'.
- In the window that appears, press 'Open' yet again.
(Windows 10 and later)
- Go to the releases section.
- Download the
.exefile. - Double-click the
.exefile, wait for installation, profit.

You can track all the progress here: https://github.com/orgs/upscayl/projects/1
- Fix bugs
- Make the whole world use FOSS (WIP 🚧)
I recommend using Volta (https://volta.sh) for installing Node.js.
Download and install volta, then do: volta install node.
You can also use pnpm instead.
You can download pnpm here.
Note
If you are not willing to install git, you can skip the first line, download the source zip and extract it to upscayl instead and carry on with the rest of the instructions.
git clone https://github.com/upscayl/upscayl
cd upscayl

npm run publish-app- How does Upscayl work?
- Upscayl uses AI models to enhance your images by guessing what the details could be. It uses Real-ESRGAN to achieve this.
- Is there a CLI available?
- The CLI tool is called real-esrgan-ncnn-vulkan, and it's available on the Real-ESRGAN repository.
- Do I need a GPU for this to work?
- Yes, unfortunately. NCNN Vulkan requires a Vulkan-compatible GPU. Upscayl won't work with most iGPUs or CPUs. But hey, no harm in trying ;)
- How can I contribute?
- You can report issues, fix code and add features by submitting PRs, or donate! 😊
- What's the GPU ID for?
- It is for selecting which GPU to use. The specific procedure is detailed in the Wiki.
- Note that for Windows systems, if Upscayl is not set to performance mode, the system may override this setting.
- It is for selecting which GPU to use. The specific procedure is detailed in the Wiki.
- You are not fully open source!!😡
- We are! We're using completely free and open-source tech. We do ship a binary, but that's because not including it would kill the entire purpose of the project. If you want to deal with all those PyTorch, NCNN, and Python errors, you're more than welcome to compile your own binary using the code provided by Real-ESRGAN. The binary is pre-compiled for convenience; if you do not trust it, then you can compile your own since everything is free and open source here 😁
- Where do I find more models?
- More models can be taken from here: https://github.com/upscayl/custom-models/
Upscayl uses Real-ESRGAN-ncnn-vulkan binaries to upscale images.
