IrfanView is a simple image editor and viewer which offers many features whilst consuming very few system resources. It supports numerous file formats including: image formats such as BMP, GIF, JPEG, PNG (includes the optimizer PNGOUT), TIFF, non-image media files such as Flash, (Ogg) Vorbis, MPEG, MP3, MIDI, and text files. The program has built-in TWAIN support for retrieving images from scanners; it also has extended support for taking screenshots. In addition to extensive viewing capabilities and file conversion options, IrfanView can also create screensavers and slide shows from collections of images with optional accompanying mp3 audio.
These screensavers and slide shows can be created as “stand-alone” executables that will run on computers which do not have IrfanView installed. IrfanView is designed to be a lightweight viewer/player noted for its speed, ease of use, and the ability to handle a wide variety of graphic file formats. IrfanView is also compact: the latest version is less than 1200 kB in size, although several megabytes of plugins are available to support numerous other file formats and features.
