IrfanView 64-bit version

Starting with IrfanView 4.40 there is also a 64-bit version available.

Advantages of IrfanView 64-bit over 32-bit version:

  • It can load VERY large files/images (image RAM size over 1.3 GB, for special users)
  • Faster for very large images (25+ Megapixels, loading or image operations)
  • Runs 'only' on a 64-bit Windows (Vista, Win7, Win8, Win10, Win11)

Advantages of IrfanView 32-bit over 64-bit version:

  • Runs on a 32-bit and 64-bit Windows
  • Loads all files/images for normal needs (max. RAM size is about 1.3 GB)
  • Needs less disc space
  • All PlugIns will work: not all PlugIns are ported (yet) to 64-bit (like OCR) and some 32-bit PlugIns must be still used in the 64-bit version, some with limitations (see the "Plugins32" folder)
  • Some old 32-bit PlugIns work only in compatilibilty mode in IrfanView-64
  • Command line options for scanning (/scan etc.) work only in 32-bit (64-bit TWAIN drivers are rare => in case of problems, use IrfanView-32 for scanning)


  • You can install both versions on the same system, just use different folders. For example: install the 32-bit version in your "Program Files (x86)" folder and the 64-bit version in your "Program Files" folder (install 32-bit PlugIns to IrfanView-32 and 64-bit PlugIns to IrfanView-64, DO NOT mix the PlugIns and IrfanView bit versions)
  • The program name and icon have some extra text in the 64-bit version for better distinguishing
