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?– KCotreauJun 29, 2011 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, 2011 at 7:12

The exact file type matters. Some scale (.jpg), some are pixels (.gif)– KCotreauJun 30, 2011 at 7:20

I'm talking about screenshots (taken with [Alt+]Print, then pasted), not about viewing files.– Mike L.Jul 1, 2011 at 8:38

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! Sep 11, 2016 at 1:25

1Thanks! baffling to me that there are a separate set of options which are not under the Options menu. May 28, 2019 at 23:22

2There is now an option specifically for zoom under View -> Display options -> Use Resample for zooming– TerranceJul 19, 2022 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". Apr 16, 2023 at 7:11
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'.
