Irfanview displaying an image.

IrfanView is a freeware graphics viewer and organizer program developed by Irfan Škiljan for Windows and released on 1996-06-01. It works fine on Windows 10, but has backward compatible support all the way to Windows XP. It can quickly open an view hundreds of graphic formats and has limited support for some video and audio formats as well. With the base install, the program and display BMP, CUR, EMF, GIF (and animated), ICO, JPEG, Netpbm, PCD, PNG, PSD, TGA, TIFF, WMF. With plugin support, it can view CRW, DDS, ECW, EPS, FLIF, IFF, JPEG 2000, MNG, PCX, PDF, PSP, SGI, WEBP, XBM, and many others.


After upgrading to Windows 10, I was disgusted that Microsoft had ditched Windows Photo Viewer and replaced it with the Photos application which is malware which is not only slow and bloated, but also uses facial recognition to identify the people in your photos and sends the data back to Microsoft. I searched online for a replacement and found a lot of praise for IrfanView. After trying it out for awhile, and customizing it to my liking, I now prefer it over any other.



  • With such a wide array of supported image formats, this program can replace several viewer programs.
  • There are a lot of customization features to make the program work the way you want.
  • The program is a fantastic replacement for the awful Photos program that comes with Windows 10.
  • Unlike many photo viewers, this doesn't send your private information to a major corporation.
  • The program also includes some primitive photo editing features if you don't have access to a decent editor.


  • A large portion of the formats are not included in the default installer, and require you to install a second plugin. I would prefer they just all be included in the same installer.
  • By default, the scroll-wheel is set to move to the next image rather than zoom. You also can't use the scroll wheel to zoom, but must use the stupid Adobe method of CTRL+Scroll to zoom. Also, when you can't see the full image if you're zoomed in too far, you can't use the arrow keys to move to the next image.
  • By default, the viewer is set to open a lot of formats you probably won't want it to open, like fonts, text files, and MIDI files. These can be disabled in the settings, but it's not simple. I would prefer a simpler UI which allowed you to easily enable/disable all formats of a specific type like images, video, audio, documents, etc.
  • The default icons are very old and ugly looking.


  • Nothing.
