    Real-ESRGAN Batch Upscaling using Google Colab

    There are probably some better ways of pre-processing images out there, but this is what I usually do with my dataset preparation. If someone want to upscale images with Real-ESRGAN using Colab, this may be for you.

    Google Colab link:

    https://colab.research.google.com/github/minionphak/Advanced_Real_ESRGAN_Upscaling_-_Batch_Processing/blob/main/Advanced_Real_ESRGAN_Upscaling_%26_Batch_Processing.ipynb

    The Colab script include some features like:

    • Upscaling image with Real-ESRGAN

    • Processing multiple folders

    • Rescaling image by side or specific resolution

    • Cropping image to specific ratio for bucket when training LoRA

    • File converting to png, jpg, jpeg

    • Zip the file

    Not complicated to use. Good luck!

    There are errors on some toggle options (conflicting). I'm going to check them later :D
