IrfanView Overview
IrfanView is a fast, compact image viewer, converter, and editor for Windows, long valued for its speed and small footprint. It opens a very wide range of image (and some audio/video) formats almost instantly, and includes practical editing tools: crop, resize, rotate, color adjustments, and basic effects. A standout feature is its powerful batch processing, which can convert, rename, and apply edits to large numbers of files at once. Optional plug-ins extend its format support and capabilities. IrfanView is free for personal and educational use. A portable version is also available that runs without installation, which suits support kits and USB toolkits. It also supports scanning through TWAIN, simple painting tools, and building slideshows or self-running presentations, and a 64-bit build handles very large images.
