Hi..I love this program very-very much. I use it very regularly. It can load image faster then any other image viewer(i think). Try this ok!..

I'm using this baby for years for fast stuff (paintshop pro for the rest) and it is just great. Besides the ability of using photoshop plugins irfanview also creates great html image galeries, multiple image aopperations throug thumbnails an almost everything else besides serious editing.
This is all you need. I dare you to prove me wrong :-)

The finest light weight, speedy, simple, unencumbered, non-dependant and versitile graphics programme I have used. Had it for years and at a minimum it works great as a graphics clipboard.

The only limitation I have found is that it can't deal with large files copied and pasted from photoshop.

I find that running it from a flash drive messes up whatever settings (eg associations and shell menu settings) were set by the Irfanview on the host's hard drive. It's overwriting settings kept by the registry! This is not safe "portable app" behavior, especially if I'm doing this on someone else's machine.

IrfanView is not stealth or even just portable when you activate file associations or shell functions. For this the exe has to be alway on the same place. On a fresh machine or if you move the app folder you need to reregister your desired file associations and of course they are written to the registry. ALL other settings are portable via ini.

Get the portable version here:

Cogmios 2008-04-20 15:28

Is there ANY way to work around the file-associations thing? If an USB user re-sets the file associations to his "F: drive" installation this causes problems for the original owner of the PC. I realize it is a Windows thing but I hope someone has a clue to maybe solve this/workaround.

Kermode 2008-05-31 13:35

The normal version if portable enough, the new machine doesn't know to call the program if someone clicks on a picture - because guess what - it hasn't been associated with that program. But that's not the programs fault, there is no reason to use a separate launcher.

Faststone is MUCH better!!!

DeepAnger 2009-01-02 01:01

I've tried a lot of alternatives for years. None is as fast as IrfanView, especially in large folders with lots of files. It's the best and the only other picture viewer I use is XnView for its easier way to handle dual screens.

I was unable to find a mirror that would let me select a ZIP file. What was I doing wrong?

What I like is that it can make Windows Icons out of any image - so can Gimp by the way.
- Peace!!! masses

For the File Associations, Shell extensions (Right-click) and other Registry issues, especially in a multi-user environment, have a look at ASSOX
Off-topic (not portable)
IrfanView's find for quick-and-dirty icons, but for making proper Windows ICO files (14 different size/resolution in one file - see, better to use Photoshop and the Icon Plugin from here

Best way I find to make IrfanView portable-friendly is to run a PC-installed version (with Plugins), go to Properties/Settings, under Extensions 'Clear all', then uncheck any 'Shell options'. Then copy the whole IrfanView folder to your USB drive. After doing that, re-enable the extensions and shell options on the install PC. I just drag-and-drop images into an open instance since there won't be file associations on the host machine.

Loving the lossless jpg crop and rotation capabilities. Remarkably simple and effective. Fantastic for already faded photos you don't want to lose any quality / file size on.

TAIMAT 2010-12-17 17:14

switched to xnview long time ago .. but my respect for irfanview never ceased

Jeff Alexander 2011-05-19 09:22

This is a great piece of software: simple to use and performs almost any task. I especially like the custom/fine rotation feature which allows you to rotate images to a fraction of a degree both right and left. The batch rename and convert feature is fantastic too. It allows you to save in any format. Like many others, I've been using it for years and highly recommend it. The plugins allow you to do almost any task with it and I'm still discovering new things I can do with every day. The help files are easy to follow and it has a nice, clean, uncluttered interface. Incredibly well designed. Great program! (Did I mention it is free?)

I dislike this program,have tried many a version and just dont like multiple windows I guess-I love Xnview Portable to death!


AndTheWolf 2013-12-20 16:59

Secunia PSI is flagging 4.36 as having security issues. The page and the link should probably be updated to 4.37.

Irfanview is one of the oldest, but still one of the best programs of its type. Does just about everything, its fast and very lightweight, and even works from the command-line.


zorro 2017-10-14 20:18

Attention! Version 4.50 changes the ini-file to unicode (UTF16 LE) - as a side-effect the dropdown-zoombox in the menu (if activated) doesn't show up the percentage-steps any more, only %%. You can still type in the desired percentage and press enter, but the predefined steps don't work. This sure will be corrected, but if someone can't live with that: stay with V4.44 until next version.


zorro 2018-02-28 06:26

As mentioned above the problems with unicode were solved. Zip now contains a text file with following advise:

>> Please start IrfanView and call (once) any of the dialogs:
- Properties (P), or
- File->Open (O), or
- File->Save As (S), or
- Batch (B)
to convert/set IrfanView INI file to UNICODE mode !

If the INI file is not converted to Unicode, some of the options (like filenames, paths or text options)
may NOT be saved properly and the feature may not be working as expected.
