MetadataViewerMetadata guides
What your files reveal, how to check them, and how to clean them — written to be actually followed, not skimmed.
Understand what files reveal
Start with EXIF fields, GPS tags and C2PA Content Credentials. Each guide separates editable metadata evidence from proof and documents what the local parser can and cannot establish.
Remove metadata, then verify
Photo and Office guides compare built-in platform controls with the browser tools. Keep the original, clean a copy, and inspect that downloaded copy instead of trusting a success message alone.
