text: Features IrfanView is specifically optimized for fast image display and loading times. It supports viewing and saving of numerous file types including image formats such as BMP, GIF, JPEG, JP2 & JPM (JPEG2000), PNG (includes the optimizer OptiPNG; APNG can be read), TIFF, raw photo formats from digital cameras, ECW (Enhanced Compressed Wavelet), EMF (Enhanced Windows Metafile), FSH (EA Sports format), ICO (Windows icon), PCX (Zsoft Paintbrush), PBM (Portable BitMap), PDF (Portable Document Format), PGM (Portable GrayMap), PPM (Portable PixelMap), TGA (Truevision Targa), WebP, FLIF (Free Lossless Image Format) and viewing of media files such as Flash, Ogg, Vorbis, MPEG, MP3, MIDI, and text files.
  Image editing includes crop, resize, and rotate. Images can be adjusted by modifying their brightness, contrast, tint, and gamma level manually or automatically, and by converting them between file formats. Many of these changes can be applied to multiple images in one operation using batch processing.
  A plugin allows IrfanView to support lossless JPG operations: horizontal or vertical flip, rotation by 90° increments, and cropping.
  Plugins
  IrfanView uses plugins to handle several additional images, video, and sound formats and to add optional functionality such as filter processing or other program features. With its diverse set of format plugins, the program has been recommended for viewing obscure image formats, or corrupted files, which commercial photo editing software cannot read.
  Search engine toolbar
  Prior to version 4.41 installer versions of IrfanView supported a number of browser toolbars. Version 4.40 optionally installed the Amazon 1Button App (formerly the Amazon Browser bar).
