New Irfanview now available in 64 bit version

A new version of IrfanView and plugins has been released.
IrfanView - Official Homepage - one of the most popular viewers worldwide

You can now install a 64 bit version.
You can install both versions, as long as they have their own folders (i.e. one in "Program Files" and the other in "Program Files (x86)").

Make sure that you choose the correct plugin pack for the version you install.

Nice find. Thanks! :)

IrfanView is one of the first programs I install in Windows (has been for 10+ years).

It is the most useful multi-format file viewer (audio, picture, video and others) I've ever tried.

The 64 bit version is a nice improvement.

What are the advantages of 64bit IrfanView over the 32 bit version (which I consider a necessity on my computers).

Thanks. I will have to try Irfanview 64bit with the separate Ghostscript 64bit plugin and see if it works!

I read some info somewhere that suggests that the 64 bit version is faster when loading large images.

It seems faster on my PC, but I don't know any way to generate the necessary data to prove it. :)

In IrfanView - open an image then select Image> Information and you will see the "Loaded In" speed.

I've checked load time for a test image in IrfanView 32bit and will compare the same image once I've installed the 64bit version.

Irfanview 32bit vs 64bit image loading speed.

A test using the same image.

Irfanview 32bit loads a 4.75Mb jpeg image in 749 milliseconds.

Irfanview 64bit loads the same image in 671 milliseconds.

That is actually faster than Wildbit Image Viewer (733 milliseconds for the same image)

Thanks for that tip.


Here's my test with a 51.2 MB tif (5184px x 3456px):

The benches look impressive but in real time usage, a 38% increase from 78/100 of a second isn't going to be at all noticeable unless working with several hundred images or files at a time.
