## What it is
Exiv2 is a cross-platform C++ library and command-line utility for reading, writing, deleting, and modifying Exif, IPTC, XMP, and ICC image metadata. It is widely embedded in desktop applications such as GIMP, darktable, and KDE/GNOME tools.

## Use cases
- read exif data from jpeg photos
- strip gps metadata from images before sharing
- batch edit iptc captions on photos
- extract xmp metadata from raw image files
- command line tool to print image metadata tags
- embed copyright info into photos programmatically
- extract thumbnails from image files

## When to choose
- you need fast, reliable Exif/IPTC/XMP manipulation in C++ or via CLI
- you are building photo management or editing software
- you need Makernote support and metadata conversion between formats

## When to avoid
- you need a high-level scripting library in Python or JavaScript rather than C++
- you only need basic image processing without metadata concerns
- you require a permissive license, as Exiv2 is GPLv2

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, cli, parser
- domain: image-processing, photography, media, developer-tools
- platform: cross-platform, cpp, cli, windows
- tags: exif, iptc, xmp, icc-profile, metadata, c-plus-plus, linux, macos
