There is a free program called Upscayl which uses AI and is free. You can get it on GitHub or their site

Woah, this looks so sleek! Thx for the link!

If you can’t use locally run AI programs like EasyDiffusion and prefer Perchance, you could try Upscayl. It’s a free program (on GitHub) that uses AI to upscale your images, using different filters you can chose from.

I don’t know if I can post a link to the site itself here, but you can easily find it with “Upscayl github”
