Image Metadata Marker Check
Check whether a JPEG, PNG or WebP image contains recognized EXIF or XMP blocks or a supported C2PA marker. This local check does not read camera, date, GPS or other metadata values, C2PA claims, or signatures.
Drag and drop an image to check metadata markers
Looks for EXIF, XMP, or C2PA markers in this browser. It does not read metadata values or C2PA claims, or validate signatures. Supports JPEG, PNG, and WebP up to 20 MB.
What this check looks for
Supported metadata and provenance markers
The result reports whether supported blocks or markers are present. It does not open or display the values inside them.
Recognized EXIF block
The tool detects a supported EXIF block in the image structure. It does not read camera, date, exposure, or GPS values.
Recognized XMP block
The tool detects a supported XMP block. It does not display text, editing history, or any other XMP values.
Supported C2PA marker
A marker is a structural clue only. The tool does not read C2PA claims or validate signatures.
How to interpret the result
A detected marker only means that this tool found a supported block or marker in the file structure. It does not establish that a photo came from a camera, that metadata is complete, or that any recorded information is accurate. A missing marker also does not show whether an image is authentic or AI-generated.
Frequently Asked Questions
What is EXIF data?
EXIF is a format that can store information in an image file. This checker only looks for a recognized EXIF block; it does not read any values stored inside it.
What does this image metadata checker inspect?
It looks for recognized EXIF and XMP blocks and a supported C2PA marker in JPEG, PNG, or WebP images. It does not read camera, date, GPS, or other metadata values, C2PA claims, or signatures.
Does an EXIF or C2PA marker prove that a photo is authentic?
No. A marker is only a structural clue. This check does not read metadata values or C2PA claims, validate signatures, or establish where an image came from.
Why might an image have no recognized marker?
An image may never have contained one, or an export, edit, screenshot, or sharing service may have removed it. No marker is not evidence that an image is real or AI-generated.
What is the difference between EXIF and XMP?
They are different ways image files can store metadata. This checker can detect supported EXIF or XMP blocks, but it does not inspect their contents.
