Metadata Extractor is a straightforward Java library for reading metadata from image files.

Metadata metadata = ImageMetadataReader.readMetadata(imageFile);

With that object, you can iterate through all the tags it contains, or query out specific values.

The library understands several formats of metadata, many of which may be present in a single image:

• Exif
• IPTC
• XMP
• JFIF / JFXX
• ICC Profiles
• Photoshop fields

It will process files of type:

• JPEG
• TIFF
• Camera Raw (NEF/CRW/CR2/...)

Special camera-specific data is decoded for most cameras manufactured by:

• Canon
• Nikon
• Sony
• Minolta
• Casio
• Pentax
• Panasonic
• Fujifilm
• Olympus
• Agfa
• Epson
• Kodak
• Sigma/Foveon
• Kyocera
