• Reading metadata. ExifTool allows extracting detailed information from metadata stored in files. This includes EXIF, IPTC, XMP, GPS, and other data, displaying values such as creation date, camera model, exposure settings, and geographic location.
• Editing metadata. The tool enables modifying specific fields within the metadata. Values such as author, title, description, and keywords can be updated without altering the main content of the file.
• Removing metadata. ExifTool can selectively delete metadata to protect privacy or reduce file size. It is possible to remove EXIF data, GPS information, or entire metadata blocks.
• Support for multiple formats. It works with image formats such as JPEG, PNG, TIFF, RAW, as well as video files (MP4, MOV), audio (MP3, WAV), and documents (PDF, DOCX).
• Batch processing. Allows applying read, write, or edit operations to multiple files simultaneously, optimizing the handling of large data collections.
• Report generation. ExifTool can export metadata in different formats, including plain text, HTML, XML, and JSON, facilitating analysis and information storage.
• Metadata conversion. The tool converts between different metadata standards, such as EXIF to XMP or IPTC to EXIF, maintaining structure and compatibility.
• Thumbnail extraction. Can retrieve embedded thumbnail images from RAW or JPEG files, saving them as standalone files.
• Metadata validation. Detects inconsistencies or errors in metadata, such as out-of-range values or incorrect formats, helping to maintain data integrity.
• Script integration. ExifTool can be used in combination with scripts in Perl or other languages to automate complex metadata processing tasks.

ExifTool was created by Phil Harvey in 2003. It is written in Perl and is compatible with Windows and macOS systems. Harvey continues to maintain and update the project, adding support for new formats and functionalities. The tool is widely used in digital photography, archiving, and forensic analysis.
