I have a bunch of lossless optimized png's which I want to resize/shrink. Whenever I try to resize them the filesize is actually getting bigger. I've tried Imagemagick and Irfanview. This kinda doesn't make any sense to me. Since I'm more comfortable with Irfanview than Imagemagick I'm asking for a solution for Irfanview.
Any ideas?
Version: Irfanview 4.40 64bit on Windows 10
My Irfanview options for resize and save.
