Overview

Upscayl is an open-source desktop application for enlarging and enhancing images with AI models. It uses neural-network upscaling to increase image resolution while reconstructing detail more effectively than traditional interpolation, making it useful for old photos, digital artwork, compressed images, and low-resolution graphics. The application provides a graphical interface so users can apply AI upscaling without working directly with command-line model tools.

Upscayl runs locally and is available across major desktop operating systems, with GPU acceleration used when supported by the hardware. Users can select different enhancement models and process images without uploading them to a cloud service, which is attractive for privacy-sensitive workflows. It is a straightforward choice for creators and general users who need higher-resolution images and prefer a free, open alternative to commercial AI image-enhancement services.

👨‍💻 Installation

[!IMPORTANT] You'll need a Vulkan compatible GPU (Graphics Card) to upscale images. Many iGPUs (integrated graphics) do not work but, no harm in trying :)

🐧 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 or our official website.
Download the upscayl-x.x.x-linux.AppImage file.
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

(MacOS 12 and later)

Link

Go to releases section or our official website.
Download the upscayl-x.x.x-mac.dmg file.
Double click dmg, drag Upscayl icon into Applications folder.
Open Finder, click 'Applications' tab in the left sidebar. Find Upscayl and right click on it. Select 'Open'.
In the window that appears, press 'Open' yet again.

🍺 Homebrew

brew install --cask upscayl

🐌 Windows

(Windows 10 and later)

Go to releases section or our official website.
Download the upscayl-x.x.x-win.exe file.
Double click exe file to launch.
If you get a SmartScreen warning - click 'More Info' and then 'Run Anyway' OR press 'YES' on the unverified publisher dialog.
Follow the installation steps.
Profit!

🛠 Development

I recommend using Volta: https://volta.sh for installing Node.js. Download and install volta, then do: volta install node.

🏃 Running

[!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

🤓 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...
I stopped the magic Batch Upscayl and my images haven't been processed, compressed, or are in the wrong scale!
- When a model doesn't support an action, Upscayl will finish upscayling all the images first before post-processing them. What this means is that you should simply wait for the process to finish.
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
