Blurry pixel art icon

I’m using unity on windows and I am setting the custom icon as pixel art that I drew and it is looking fine in the editor but when I build the icon is blurry and I can’t find a fix to it.

Did you set “Point (no filter)” filter mode in import settings?

Make it in a big resolution like 1000x1000, you should be able to resize it on most software and it will keep the pixel art look
