EXIF vs XMP vs IPTC: Photo Metadata Types Explained

When we talk about hidden data in photos, most people think of GPS coordinates. But image files can carry three entirely separate metadata systems — and each stores a different kind of information about you, your device, and your workflow. Understanding the difference between EXIF, XMP, and IPTC matters if you want to properly protect your privacy, or if you work with images professionally.

What Is EXIF Metadata?

EXIF (Exchangeable Image File Format) is the oldest and most widely used of the three standards. It is written directly by the camera or phone at the moment a photo is captured and stored inside the image file itself.

What EXIF typically contains:

• GPS latitude, longitude, and altitude
• Date and time of capture (to the second)
• Camera make and model
• Camera serial number (not always, but often)
• Lens model and focal length
• Aperture, shutter speed, and ISO
• Flash status
• Image orientation
• Colour profile and white balance

EXIF is the standard most associated with privacy risks, primarily because of the GPS field. A photo taken at home on a standard smartphone embeds coordinates accurate to within a few metres.

What Is XMP Metadata?

XMP (Extensible Metadata Platform) was developed by Adobe and introduced in 2001. Unlike EXIF, XMP is designed for software to read and write — it records what has happened to an image after it was captured.

What XMP typically contains:

• Edit history from Lightroom, Photoshop, or other Adobe tools
• Star ratings and colour labels
• Keywords and tags applied during cataloguing
• Copyright information and usage rights
• Creator name and contact details
• Caption and description text
• The name of the software used to edit the image

For photographers, XMP is essential for workflow. But the copyright and creator fields often contain a photographer's full name, website, and contact email — information that travels with every image shared from their library.

XMP data can be stored inside the image file (embedded) or in a separate sidecar file with a .xmp extension. For JPEG files, it is typically embedded.

What Is IPTC Metadata?

IPTC (International Press Telecommunications Council) developed its own photo metadata standard in the 1990s, primarily for use in news and editorial photography. It defines fields for captions, credits, keywords, and rights information that news agencies needed to exchange with newspapers and wire services.

What IPTC typically contains:

• Caption and description
• Credit line and photographer byline
• Copyright notice
• Source and provider
• Headline
• Keywords and subject codes
• City, state/province, and country fields
• Special instructions for editors

IPTC fields are still widely used by professional photographers, picture desks, and stock image agencies. Many cameras and professional editing tools allow you to embed IPTC data as a template that is applied to every image you process.

How Do the Three Standards Overlap?

There is significant duplication between the three standards. The same piece of information — a copyright notice, for example — might appear in all three simultaneously. When you open an image's properties in different software tools, you may see the same field listed under EXIF, XMP, and IPTC depending on which standard the tool prioritises.

This duplication is one reason why stripping metadata properly is more complex than deleting a single field. A tool that only removes EXIF may leave XMP or IPTC data intact.

Which Standard Poses the Greatest Privacy Risk?

For most people, EXIF is the primary risk because of GPS data. The coordinates recorded by a smartphone can identify your home, workplace, school, or any other regular location with high accuracy.

For professionals, XMP introduces additional risks through the creator and copyright fields, which often contain a full name, email address, and website URL embedded in every image.

IPTC is the least risky for most casual users, but professional photographers who use IPTC caption templates may inadvertently embed their contact details in every exported image.

Does Removing Metadata Remove All Three?

Only if the tool is designed to do so. Some tools only strip EXIF. ExifVoid removes all three — EXIF, XMP, and IPTC — because it uses canvas re-encoding rather than selective field deletion. The re-encoded image starts fresh with no embedded metadata at all.

When you scan a photo with ExifVoid, the results display fields from all three standards, organised by category so you can see exactly what is embedded before removing it.

Frequently Asked Questions

Does removing EXIF data also remove XMP and IPTC?

Not necessarily. Tools that use selective field deletion may only remove EXIF. ExifVoid removes all three by re-encoding the image from scratch.

Can I add my own EXIF, XMP, or IPTC data to a photo?

Yes. Tools like Adobe Lightroom, ExifTool (command-line), and many others allow you to write custom metadata into any of the three standards. This is common practice for photographers who need to embed copyright or contact information.

Are metadata standards the same for all image formats?

Not exactly. EXIF is most commonly associated with JPEG and TIFF. PNG files can carry EXIF and XMP but support is inconsistent. RAW files from different camera manufacturers use proprietary extensions of the EXIF standard. WebP supports EXIF and XMP. ExifVoid works with JPEG, PNG, WebP, and HEIC.

Which software writes XMP metadata automatically?

Adobe Lightroom Classic writes XMP sidecar files automatically for RAW files and embeds XMP into JPEG exports. Lightroom Mobile, Capture One, and other editing tools behave similarly.
