What Is File Metadata?
File metadata is embedded information about a file — such as creation date, author, dimensions, and technical settings — stored alongside the actual content.
File Metadata explained
File metadata is structured information embedded within a file that describes properties of the file itself rather than its visible content. For images, this includes dimensions, color space, camera settings (EXIF), GPS location, creation date, and software used. For documents, metadata may include author name, organization, revision history, and creation/modification timestamps. For audio and video, it includes codec, bitrate, duration, and tags like artist and album. Metadata is valuable for organization and workflow, but it can also be a privacy concern — sharing a photo with embedded GPS coordinates reveals where it was taken. During file conversion, metadata handling varies: some converters preserve all metadata, some strip it, and some allow selective retention.
