v2 will release soon. We're kinda busy with other things at the moment so sorry for the delay, thanks for the support :)

Upscayl 🆙

Free and Open Source AI Image Upscaler

Upsacyl.Demo.mp4

Upscayl is a cross-platform application built with the Linux-first philosophy. This means that we prioritize Linux builds over others but that doesn't mean we'll break things for other OSes :)

NOTE: Upscayl does not work without a GPU, sorry. You'll need a Vulkan compatible GPU to upscale images. Most CPU and iGPUs won't work.

Installation 👨‍💻

Linux 🐧

1. Go to releases section

2. Download the .AppImage file.

3. Right Click AppImage -> Go to Permissions tab -> Check allow file to execute and then double click the file to run Upscayl.

You can also download the flatpak version and double click the flatpak file to install via Store but wait for the full release, we'll be pushing it to Flathub for easy access.

MacOS 🍎

1. Go to releases section

2. Download the .dmg file.

3. Double click dmg, drag Upscayl icon into Applications folder.

Windows 🐌

1. Go to releases section

2. Download the .exe file.

3. Double click exe file, wait for installation, profit.

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 more in the future) model 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 on most iGPUs or CPUs.
• How can I contribute?
  • You can donate more NCNN compatible models or fix code by submitting PRs :)
• 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 :)

Upscayl uses Real-ESRGAN-ncnn-vulkan binaries to upscale images. More models and algorithms will come soon.
