🆙 Upscayl
Free and Open Source AI Image Upscaler
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 CPU and iGPUs do not work but no harm in trying.
👨💻 Installation
🐧 Linux
Upscayl should be available on the software listings of most Linux operating systems. Your distro's Store app might also support the Flatpak or Snap version.
💼 Portable Method
- Go to releases section

upscayl-x.x.x-linux.AppImagefile. - Right Click AppImage -> Go to 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 x86 Linux OS).
🍎 macOS

- Fix bugs
- Make the whole world use FOSS (WIP 🚧)
🛠 Development
I recommend using Volta: https://volta.sh for installing Node.js.
Download and install volta, then do: volta install node.
🏃 Running

If you are not willing to install git, you can skip the first line, download the source zip and extract it to
upscaylinstead and carry on with the rest of the instructions.

🤓 FAQ
- How does Upscayl work?
- Upscayl uses AI models to enhance your images by guessing what the details could be. It uses Real-ESRGAN and Vulkan architecture to achieve this. Our backend is fully open-source under the AGPLv3 license.
- I don't see a drastic change in my upscaled image. Why is that?
- Upscayl can enhance low resolution images and images that are pixelated but it cannot de-blur or do focus adjustment on your image. If your image is out-of-focus or totally blurred, Upscayl is not the right tool for it. Please use images that are similar to the examples we've given here.
- Is there a CLI available?
- The CLI tool is called upscayl-ncnn.
- 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 ;)
- @Wyrdgirn has contributed a workaround for Windows and Linux in #390! Nobody knows how to manipulate the macOS and Haiku frameworks...
- 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.

- 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.
