IrfanView

Yes, direct download links for IrfanView and Plugins are available on the official website. For IrfanView, visit the IrfanView website and scroll to the end of the page for alternative links. For Plugins, check the Plugins page for the alternative link.

On a normal system, the installer will ask for admin permissions at the start. Allow this to install in the standard folder like 'Program Files' and write basic program info in the system registry. If your system doesn't ask for admin permissions, right-click the EXE installer, choose 'Run as administrator,' and verify. Advanced users can use the ZIP version and unzip into a folder with write permissions.

Probably not. All basic options, features, and PlugIns are included in the standard IrfanView installation. PlugIns usually contain special file formats. If you need a specific PlugIn, IrfanView will show an error message, and then you can install the required PlugIns.

Start IrfanView, go to 'Properties->Extensions,' and associate your file types. Note: In newer Windows versions, you must start IrfanView in admin mode to change file associations. Right-click IrfanView, use the 'Run as admin' menu, and verify. If still not working, use System Settings (or Control Panel): Apps => Default Apps => Photo Viewer (Set IrfanView as the default program).

There may be a system problem in some Windows 11 installations caused by the 'Microsoft Photos' app. Try this: Start System Settings, go to 'Apps,' then 'Apps and Features.' Find 'Microsoft Photos,' click on the menu on the far right (3 dots), choose 'Advanced options,' and perform both the Repair and Reset (sometimes you need to start and close 'Microsoft Photos' after this). Now you can associate JPG, etc., with IrfanView in 'Apps -> Default Apps.' Alternatively, uninstall and reinstall IrfanView with admin rights and avoid setting associations in the installer.

IrfanView does not play videos directly; it starts the installed codecs. If you get an error like 'Video not available, cannot find decompressor,' the correct video codec is not installed or is too old. Check the codec name in IrfanView under 'Image->Information' and install the right/newer codec from sites like Codec-Guide, Free-Codecs.com, or FOURCC.org. A good codec pack is the K-Lite Codec Pack, which contains most popular video/audio codecs.

Yes, IrfanView (32-bit) is compatible with Windows 11, 10, 8, 7, and Vista 64-bit. Ensure you run the installer with admin permissions to avoid any issues during installation or when changing system settings.

No, IrfanView does not contain spyware or viruses. However, be cautious when downloading from software sites not listed on the official Downloads page, as some sites may use custom/unknown downloaders that could contain malware or ask you to pay for a free download. Always verify the original filenames and SHA-checksums of IrfanView and Plugins installer on the Downloads page.
