Metadata is the contextual hidden data stored alongside the content of your files. While viewing it is useful, editing or stripping it is critical for maintaining digital privacy and proper document organization before distribution.
Why Edit Metadata?
- Privacy Protection: Removing GPS coordinates from photos ensures your location is not accidentally shared online.
- Anonymity: Stripping the "Author" or "Creator" tags from PDFs obscures who originally drafted the document.
- Organization: Consistently tagging files with Titles or Copyright info helps digital asset management systems index them correctly.
What tags can I edit?
Most tags found in the EXIF, IPTC, and XMP groups are highly editable. However, certain system-level tags cannot be modified directly because they reflect the physical properties of the file on the server. For example:
- File Size & Permissions: These are generated by the operating system reading the file and cannot be faked via metadata editing.
- Read-only formats: Some older file structures don't support appending new tags without breaking the file header.
If a tag is not editable, the interface will automatically protect it by displaying it as read-only text instead of an input box.
