Exiv2 Overview

Exiv2 is a 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 of images in various formats. Exiv2 is available as free software and with a commercial license, and is used in many projects.

fast read and write access to the Exif, IPTC, and XMP metadata of an image
an easy to use and extensively documented API
conversions of Exif and IPTC metadata to XMP and vice versa
a smart IPTC implementation that does not affect data that programs like Photoshop store in the same image segment
Exif Makernote support:
- Makernote tags can be read and written just like any other metadata
- a sophisticated write algorithm avoids corrupting the Makernote
a simple interface to extract previews embedded in RAW images and Exif thumbnails
set and delete methods for Exif thumbnails

print Exif, IPTC and XMP image metadata in different formats: Exif summary info, interpreted values, or the plain data for each tag (a sample is here)
set, add and delete Exif, IPTC and XMP image metadata from command line modify commands or command scripts
adjust the Exif timestamp (that's how it all started...)
rename Exif image files according to the Exif timestamp
extract, insert and delete Exif, IPTC and XMP metadata and JPEG comments
convert from Exif and IPTC to XMP properties and vice versa
extract previews from RAW images and thumbnails from the Exif metadata
insert and delete the thumbnail image embedded in the Exif metadata
print, set and delete the JPEG comment of JPEG images
fix the Exif ISO setting of picture taken with Canon and Nikon cameras
