Upscayl Download: Free AI Image Upscaler for Your PC

Upscayl makes AI upscaling as simple as choosing an image and clicking a button. It uses Real-ESRGAN-based models and Vulkan, so everything happens on your own graphics card and no files are uploaded anywhere.

What does Upscayl do?

• AI upscaling: Enlarges and enhances low-resolution or pixelated images.
• Batch mode: Upscale a whole folder at once, with optional compression or scaling afterwards.
• Custom models: Load additional community models from the project’s custom-models repository.
• GPU choice: Pick which graphics card to use with a GPU ID setting.
• Command-line backend: upscayl-ncnn for scripts.

Note that it cannot fix blurry or out-of-focus photos; it is meant for low-resolution images.

Who is it for?

It suits photographers, designers and anyone who wants sharper, larger images without a subscription or uploading files.

How to install

• Windows 10 or later: Download the upscayl-x.x.x-win.exe installer and run it. If SmartScreen warns you, choose “More info” and then “Run anyway”.
• macOS 12 or later: Get it from the Mac App Store, download the .dmg, or use Homebrew:

brew install --cask upscayl

• Linux: AppImage, Flatpak (org.upscayl.Upscayl on Flathub), Snap, RPM, DEB or the AUR package upscayl-bin.

Hardware requirements

• GPU: A Vulkan-compatible graphics card is required.
• Integrated graphics and CPU: Most integrated GPUs and CPU-only setups do not work, although you can try.
• Systems: Windows 10+, macOS 12+ and Linux.
