Image Metadata Explained: EXIF, IPTC, and XMP

Digital images carry metadata: camera settings, GPS location, copyright, keywords. Understanding which metadata to keep and which to strip improves both privacy and file size.

EXIF: Camera and Photography Data

EXIF is written by cameras automatically: shutter speed, aperture, ISO, focal length, GPS coordinates, timestamp. File size impact: 20–50KB per image.

Privacy Implications

EXIF GPS data reveals where photos were taken. Photographers often strip EXIF before uploading to web or social media for privacy and security.

IPTC: Editorial Metadata

IPTC stores copyright, author, keywords, description, and usage rights. Photographers use IPTC to embed copyright and licensing information.

XMP: Extensible Metadata

XMP is a newer, more flexible standard. Stores EXIF, IPTC, and custom data. Used by Photoshop, Lightroom, and modern tools.

Which to Preserve?

For web: strip all metadata. File size reduction is 20–50KB. For archives: preserve EXIF and IPTC (copyright, date). For stock images: include keyword metadata for discoverability.

Privacy Best Practice

Before uploading to social media or sharing via email, strip EXIF. Tools like exiftool or online strippers remove GPS and other sensitive data.

Stripping Metadata

Photoshop: File > Export As > uncheck "Include EXIF". Exiftool (CLI): exiftool -all= image.jpg. Online tools: drag-drop to strip EXIF.

When to Keep Metadata

Photography archives, stock libraries, and professional workflows benefit from IPTC copyright info. General web use: strip everything.

Optimization Impact

Stripping metadata is an easy 30KB file size reduction. Use QuickConvert to convert and optionally strip metadata simultaneously.
