IrfanView is a lightweight image viewer for Windows, with functions for converting image formats, batch processing and creating slideshows. It is developed by Irfan Skiljan and offered in 32-bit and 64-bit versions for Windows XP through Windows 11. The program is distributed as freeware for non-commercial use and runs as a desktop application on the user's own computer.
The author lives in Austria, according to his own About page, so the software has an Austrian base within the EU. It is the work of an individual rather than a company, and no parent company, hosting location or data processing agreement is stated. The program is not open source, and the website does not set out commercial licence terms. An organisation that wants to use it commercially should check the licence first, and no GDPR statement was found on the pages reviewed.
