"Upscayl" (Win/Mac) free open source upscaler.

[Subpath]

"Upscayl" (Win/Mac) can be helpful for everyone
who struggles with vectorizing low resolution bitmaps

I like it. Normally it does 4x upscaling but 8x upscaling
is also possible and you can choose between different
upscaling types/modes.

@Subpath Nice find!

Guys, don't click the 'Double Upscayl' checkbox like I did, or you will end up with a huge 24000 x 17000 px image.

Guys, don't click the 'Double Upscayl'

and it will take some time too

@Subpath Yep, about 15 minutes… That setting needs to be used only on small images.

@b77

tried 8x a few times just of curiosity
4x fits my regulary needs

was impressed the first time I used it
this upscaler does a pretty good job

This is a really cool program, but I cannot figure out how to export the resulting file. Am I missing something?

*Edit - ok looks like it automatically downloads it upon completion to the designated folder

Seems, you found it already

But just for anybody else.
Upscayle saves the result in the folder where the source image
came from.
That button "Set output folder" is misleading / does not work.

Create a new folder, put a copy of the image you like
to upscale into this folder. Scale the image, the result
is now also in this folder.
