PDF metadata, explained
PDFs can contain metadata that isn’t visible on the page but can identify the authoring tool, timestamps, or other details.
Common examples include:
- Title/Author/Subject/Keywords
- Creator/Producer (the software that created the PDF)
- Creation and modification timestamps
- XMP metadata streams
- Attachments and form data
- Annotations (comments, links)
The Deep Metadata Scrubber is designed to remove or normalize common metadata while keeping text selectable.
