\"\"<\/a><\/p>\n

Upscaler, the free open-source AI image upscaling application, released new 1.5.0 version (then v1.5.1 with quick update) in last week.<\/p>\n

The new released added sequential image processing<\/b> support. Meaning user can now open multiple images at once, then let the app enhance them one by one.<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

Besides choosing multiple images from file chooser dialog (hold Ctrl<\/code> or Shift<\/code> to select), user can also drag and drop images into app window to add them into the queue, even during the process of upscaling images.<\/p>\n

The release has ported to asyncio<\/code> and threading<\/code> Python modules, thus loading images has become much faster and smoother, while using less memory.<\/p>\n

Save the resulting images is now completely optional. Under “Completed”, user has the choice to copy image into clipboard, or click save the image as want.<\/p>\n

Relationship between Upscaler and Upscayl<\/h3>\n

Both Upscaler and Upscayl<\/a> are AI image upscaler for offline use. They use the same backend<\/a>, but target different users.<\/p>\n

Upscayl works in Linux, Windows, and macOS. But its UI for Linux does NOT look native, and the Flatpak package has permission access to network, microphone, and audio playback without asking permission.<\/p>\n

While Upscaler works only on Linux, and uses GTK4 + LibAdwaita UI toolkits for its modern UI that looks native and well integrate into Ubuntu, Fedora, etc with GNOME Desktop. And, the app package is fully restricted without file, network, etc permission access.<\/p>\n

How to Install Upscaler<\/h3>\n

The app is available to install in most Linux on AMD\/Intel platform, through Flatpak package<\/a>, which runs in sandbox environment.<\/p>\n

For Linux Mint 21\/22<\/b> and Fedora Workstation<\/b> (with 3rd party repository enabled), simply search for and install the app package either from Software Manager or GNOME Software.<\/p>\n

While Debian<\/b>, Ubuntu<\/b>, and other Linux may follow the steps below one by one to install it:<\/p>\n
