Real-ESRGAN GUI – graphical image enlargement tool

Real-ESRGAN GUI is a graphical frontend for Real-ESRGAN, a neural network-based image restoration and enlargement system. It provides an alternative to working directly with the Real-ESRGAN-ncnn-vulkan command-line utility.

The application is written in Python using Tkinter. Images are processed locally, with support for photographs, illustrations and anime artwork. Different models can be selected according to the type of image being enlarged.

One of its more useful capabilities is producing images at arbitrary sizes rather than being restricted to the scaling factors supported by individual models. The program can perform several upscaling passes and then reduce the result to the requested dimensions.

This is free and open source software.

Key Features

• Provides a graphical interface for Real-ESRGAN-ncnn-vulkan.
• Also supports the Real-CUGAN image upscaling backend.
• Enlarge photographs, illustrations, anime artwork and other raster images.
• Choose between different upscaling models, including models intended for general photographs and anime.
• Specify an arbitrary output size rather than being limited to a model’s native scaling factor.
• Perform multiple upscaling passes followed by downsampling to reach the required dimensions.
• Uses Lanczos downsampling by default, with other algorithms available.
• Process individual images or batch process images in a directory.
• Enlarge animated GIF files by extracting, processing and recombining their frames.
• Preserve frame durations when reconstructing animated GIFs.
• Drag and drop image files or directories directly onto the application window.
• Automatically generate output filenames with suffixes indicating the selected scale or dimensions.
• Adjust tile sizes to control GPU memory usage during processing.
• Use additional compatible models placed in the application’s models directory.
• Supports an alternative executable from the maintained Upscayl-NCNN backend.
• Automatically select a light or dark interface according to the desktop theme.
• Provides a multilingual interface, with English used when a translation is unavailable.
• Cross-platform support – runs on Linux, macOS and Windows.
