How can I zoom-in without having the image blurred in Irfanview? I need it for GUI development to see large pixels.

What type of files are they, and does if Infranview can't do it, does it have to be that program? – KCotreau Jun 29 '11 at 13:46

Usually, it are screenshots. Well, IrfanView is my choice of small and fast image viewer since ages. I've tried a couple of alternatives, but they lack at different areas - mostly in usability. – Mike L. Jun 30 '11 at 07:12

The exact file type matters. Some scale (.jpg), some are pixels (.gif) – KCotreau Jun 30 '11 at 07:20

I'm talking about **screenshots** (taken with [Alt+]Print, then pasted), not about viewing files. – Mike L. Jul 01 '11 at 08:38

I found the solution by reading changelog
New display option: Use Resample for zooming (Menu: View->Display options)
So from "View" menu, select "Display options" and turn off "Use resample".

Thanks--I've been wondering why suddenly Irfanview was no longer giving me a precise zoomed view of my images! – Jon Coombs Sep 11 '16 at 01:25

1Thanks! baffling to me that there are a separate set of options which are not under the Options menu. – uglycoyote May 28 '19 at 23:22

2There is now an option specifically for zoom under View -> Display options -> Use Resample for zooming – Terrance Jul 19 '22 at 20:13

There is also a separate option for when you're in full screen mode at "Options > Properties/Settings > Full screen > Use Resample function for zooming". – Jorge Luque Apr 16 '23 at 07:11

What you're looking for is technically known as "Nearest Neighbor Interpolation".
i would use an application like
- Microsoft's ZoomIt
- Magnifier
- Photoshop
they all 'preserve hard edges of pixels'.
