Exiv2 is a Cross-platform C++ library and a command line utility to manage image metadata. It provides fast and easy read and write access to the Exif, IPTC and XMP metadata and the ICC Profile embedded within digital images in various formats. Exiv2 is available as free software and is used in many projects including KDE and Gnome Desktops as well as many applications including GIMP, darktable, shotwell, GwenView and Luminance HDR.

End-User Focus

Exiv2 C++ library

  1. Fast read and write access to the Exif, IPTC and XMP metadata of an image
  2. Easy to use and extensively documented C++ API
  3. Conversions of Exif and IPTC metadata to XMP and vice versa
  4. Smart IPTC implementation that does not affect data that programs like Photoshop store in the same image segment

Exif Makernote support:

  1. Makernote tags can be read and written just like any other metadata
  2. Sophisticated write algorithm avoids corrupting the Makernote
  3. Set and delete methods for ICC Profiles
  4. Set and delete methods for Exif thumbnails
  5. The exiv2 command-line program provides a rich scripting interface for image metadata
