👨💻 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.

2. Download the upscayl-x.x.x-linux.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 choose to install using other formats like RPM (Fedora), DEB (Debian/Ubuntu based), and ZIP (Any x86 Linux OS).
