Types of metadata
explained simply

Every digital file carries hidden information called metadata. Understanding the different types โ€” EXIF, XMP, IPTC, ID3, document metadata โ€” is the first step toward controlling what your files reveal about you.

EXIF metadata โ€” photos and audio

EXIF (Exchangeable Image File Format) is the most common metadata type. It is automatically generated by cameras and smartphones when you take a photo or record audio.

What EXIF data includes

  • GPS coordinates โ€” your exact location when the photo was taken
  • Date and time โ€” when the photo was created
  • Camera make and model โ€” specific device identifier
  • Shutter speed, aperture, ISO settings
  • Focal length and flash settings
  • Image dimensions and resolution

XMP metadata โ€” creative files

XMP (Extensible Metadata Platform) is a standard created by Adobe. It is commonly used in Photoshop, Lightroom, Illustrator, and other creative applications.

What XMP data includes

  • Edit history and adjustment records from photo editing software
  • Copyright and creator information
  • Keywords and tags used for organization
  • Color profiles and editing instructions
  • Version history of the file

IPTC metadata โ€” press and media

IPTC (International Press Telecommunications Council) metadata is used by journalists, photographers, and news organizations to describe and attribute media.

What IPTC data includes

  • Creator contact information โ€” name, email, address
  • Copyright notices and usage rights
  • Headlines, captions, and descriptions
  • Categories and subject codes
  • Location information beyond GPS coordinates

Document metadata โ€” Word, PDF, Excel

Office documents contain their own metadata that can expose the author's identity and the document's full editing history โ€” even deleted content.

Audio and video metadata

What audio and video metadata includes

  • Duration and codec information
  • Creation date and time
  • Device information for recordings
  • GPS coordinates for videos shot on mobile devices
  • Artist, album, and track information (ID3 tags) for audio files

Email metadata

Email headers contain sender/recipient addresses, IP addresses of mail servers, timestamps for each processing step, authentication details, and spam scores. This is metadata you do not normally see in your inbox.
