XnView

XnView is an image organizer and general-purpose file manager used for viewing, converting, organizing and editing raster images, as well as general purpose file management. It comes with built-in hex inspection, batch renaming, image scanning and screen capture tools. It is licensed as freeware for private, educational and non-profit uses. For other uses, it is licensed as commercial software.

Although originally deployed only on Unix-like systems, it is now also available for Windows, Windows Mobile and Pocket PC. The extended version of XnView, called XnView MP, is available for Windows, macOS and Linux.

XnView has received five cows from Tucows. In 2006 Sveriges Television (SVT) recommended XnView in their High Definition Multi Format Test Set. Research papers about DICOM and digital watermarking used XnView for image processing.

Features

XnView is customisable and multi-lingual. XnView can read more than 500 image file formats, some audio and video file formats, and write 50 image file formats. XnView also supports ICC profiles in JPEG, PNG and TIFF files. It doesn't respect loop settings on animated files, however, and will infinitely loop them, regardless. Classic XnView can read image formats resulting in more than 32 bits per pixel, but write support is limited to 32 bits.

XnView can show IPTC, Exif and XMP metadata, and write IPTC metadata (It can also do batch writing of IPTC metadata). It can write XMP metadata partly together with IPTC metadata. It also supports file comments (4DOS descript.ion). XnView can search files that have the same filename or data, and can search for similar graphics as well.
