Exporting photo that looks exactly like save for web preview?

[bajahha]

Hi, everyone. Whenever i use the save for web option i find that the exported result looks worse (to me) than the one in the preview. Here  is a comparison I did between the two.

I don't really know a lot about image rendering, but when i zoom in on the picture on the right, some kind of blurring or filtering is clearly there, while the image on the left is 100% crisp. How do i get my export to look like the preview on the left?

Thanks in advance.

And btw I know that the preview says GIF and the export is png but it doesnt really matter because whatever i choose it doesn't come out that way

You need to view both at 100%!

This is critical. 100% has nothing to do with size. It means one image pixel is represented by exactly one physical screen pixel.

If you have a 4K screen, your web browser will scale up, to reproduce at a similar screen size as on a traditional screen.  This is the industry standard workaround to ensure the same material can be used everywhere, regardless of what screen technology the user happens to have.

Thanks for the explanation! in the end i got the effect i wanted by using the "index color" option in image settings
