SynthID concerns the content
SynthID embeds a signal in generated media. Removing EXIF or XMP does not establish that this signal is absent. A metadata inspector cannot run a watermark test simply by finding or deleting container blocks.
C2PA records signed provenance
Content Credentials can describe capture, editing and generation. Their presence does not automatically mean an image was generated by AI. Finding an embedded C2PA or JUMBF container is different from validating its signature, assertions and signer. Preserve the original credentials when authorship history matters.
EXIF and XMP carry other fields
Camera metadata can include dates, location and orientation. XMP may contain software or editing details. Inspect these fields for privacy before sharing. Their presence or absence is not an AI-origin verdict, and unsupported structures might not appear in the readable field table.
What the local cleanup changes
Supported JPEG, PNG and static WebP containers can be cleaned without re-encoding their image payload. Rendering information and color profiles remain; a minimal orientation tag can be retained when needed. Experimental mode instead resamples and encodes a new image, which can affect visible quality and transparency.
Compare like with like
Use container findings to assess metadata cleanup and an official detector to investigate a pixel watermark. Keep those results in separate columns. Record the original, exported file and actual settings so another test can be matched to the same bytes. A deleted credential and a negative detector result describe different observations.
This SynthID remover lab does not verify detection or removal. Metadata findings describe file blocks, not image origin.
