What Is XMP Metadata?
Published June 30, 2026
XMP (Extensible Metadata Platform) is Adobe's open, XML-based metadata standard, designed to be more flexible than either EXIF or IPTC. Rather than a fixed list of tags, XMP is built on a general-purpose, extensible schema — any software vendor can define its own XMP fields for its own purposes, which is exactly what many editing and AI tools do.
What's commonly in XMP
- CreatorTool — the specific application that created or last edited the file, frequently including the name of AI generation and editing tools
- Rating and labels applied in photo management software (Lightroom, Bridge, etc.)
- Editing history — a record of processing steps, in tools that choose to write it
- Re-expressed EXIF/IPTC fields — XMP can duplicate data from those formats in XML form, for tools that prefer to read a single unified format
- DigitalSourceType — the same standardized provenance field IPTC and C2PA can carry, which can indicate AI or algorithmic involvement
Why XMP matters for AI-content signals
Because XMP is extensible and vendor-definable, it's one of the more common places to find identifying strings left behind by AI image generators and editing tools — often in the CreatorTool field, sometimes in custom vendor-specific fields. Our Metadata Viewer includes a best-effort check against known AI-tool names found in these fields, clearly labeled as a heuristic rather than a certified detector.
How XMP is embedded
Unlike EXIF (which lives in a binary TIFF-structured segment), XMP is stored as a block of XML text, which can be embedded directly inside a JPEG, PNG, TIFF, or many other formats, or kept in a separate "sidecar" file alongside the original (common in some professional workflows, particularly for raw camera files). Only the embedded form is something our tools can read or remove from the file itself.
Removing it
The EXIF Remover does not touch XMP — for that, along with IPTC, ICC, and C2PA, use the Metadata Cleaner or, if you're specifically targeting AI-related signals like DigitalSourceType and CreatorTool, the AI Remove Tool.
