✅ Rewritten in TypeScript.
✅ Full upscalejsmodels support!
✅ Scale support (2x, 3x, 4x, and 8x!).
using upscalerjs
npm install upscaler-cli -gupscaler <img or dir> [options]
# example
upscaler align_landscape.png -m @upscalerjs/esrgan-medium -s 4x -o upscales/
Artist: stable-diffusion
Prompt: a fantastic alien landscape
Tip
If upscaling appears "stuck" - it's probably maxing out the nodejs memory limit trying to upscale the image.
Try a lower scale, or a different model to see if it improves result time.
