Easy upscale any image to 4k

Workflow is used to easily scale an image to a chosen resolution, such as 4k or 8k, without having to manually recalculate the multiplier.

Optionally, I have added the choice to change the face in the generated image.

You don't have to convert anything, WF calculates the multiplier itself and converts each image into 4K resolution, or after switching the node to 8K (as long as your machine can withstand such calculations).

Remember that SUPIR is mainly used for upscale photorealistic images and using it for less detailed images can simply be a waste of time and power.

Have fun with this WF :)
