Although originally deployed only on Unix-like systems, it is now also available for Windows, Windows Mobile and Pocket PC.[7] The extended version of XnView, called XnView MP, is available for Windows, macOS and Linux.[8]
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.[13] 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.[14] 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 XMPmetadata, and write IPTC metadata (It can also do batch writing of IPTC metadata).[15][16] It can write XMP metadata partly together with IPTC metadata. It also supports file comments (4DOSdescript.ion). XnView can search files that have the same filename or data, and can search for similar graphics as well.
The display of the histogram of a picture is possible. Scripts can be created to convert, manipulate and rename a batch of images in one go. Creation of advanced slide shows is also possible. Lossless (without new encoding) turning, flipping and cropping of JPEG files is supported.
Support for vector graphics (EPS, PS, PDF) can be integrated with Ghostscript. Classic XnView does not support Unicode, and SVG requires a commercial CAD plugin. These features are available in the multi-platform edition XnView MP based on Qt.[8]
The author published various other products using the classic or the multi-platform XnView code base, some examples are:
XnView MP — the designated successor to classic XnView which is faster, has macOS and Linux editions and has Unicode support; the current version 1.6.5[8]
