JExifViewer (commonly referred to as Java Exif Viewer) is a dedicated open-source desktop program written in Java designed to view, extract, and compare Exif metadata embedded within JPEG images. Digital cameras and smartphones use Exchangeable Image File Format (Exif) tags to automatically store technical information about a photo, such as the camera model, exposure settings, timestamp, and GPS location data.
The utility is available as an open-source project hosted on the JExifViewer SourceForge Project Page. Core Features of JExifViewer
Metadata Comparison Tables: It reads individual Exif tags and presents them side-by-side in a table format, allowing users to easily evaluate differences in camera settings between multiple images.
Built-in Image Viewer: Features include the ability to rotate, flip, and zoom in/out of selected photographs.
Slideshow Functionality: Images can be compiled and played as sequential, looped, or randomized slideshows.
File Management Tools: Users can execute basic file operations directly from the application interface, including copying, moving, deleting, and batch-renaming images.
Cross-Platform Support: Because it is built entirely on Java, the client operates universally across Linux, macOS, and Windows operating systems.
SLR Shutter Count Checker: The utility extracts manufacturer notes (such as Panasonic maker notes) to help users check the total shutter activations of digital SLR cameras. Alternate Context: Java Libraries for Developers
If you are a software developer looking to build your own Exif viewing capabilities inside a Java application rather than using the standalone JExifViewer software, the ecosystem relies heavily on programmatic open-source libraries:
metadata-extractor (by Drew Noakes): The most widely implemented Java library for extracting Exif, IPTC, and XMP metadata. Check the official implementation instructions on the Drew Noakes GitHub Repository.
Apache Commons Imaging: A pure-Java imaging library natively capable of reading, parsing, and clearing out raw metadata packages from byte arrays and stream inputs without utilizing platform-dependent codecs. Java Exif Viewer download | SourceForge.net
