Strip PDF Metadata

Wipe all identifying metadata from a PDF.

Inputs

Input PDF path (required).
Output path (optional) — defaults to <input>-clean.pdf.

What gets stripped

Document Info dictionary: /Title, /Author, /Subject, /Keywords, /Creator, /Producer, /CreationDate, /ModDate.
XMP metadata stream.
Annotations and comments (optional, ask user).

Tooling

exiftool is the most thorough — it handles both legacy Info dict and XMP.

Recipe

exiftool -all:all= -overwrite_original_in_place=false -o output.pdf input.pdf

To also remove XMP and re-linearize cleanly, follow up with qpdf:

qpdf --linearize output.pdf output-final.pdf && mv output-final.pdf output.pdf

Verification

exiftool output.pdf
pdfinfo output.pdf

Both should show empty/default values for Author, Title, Producer, etc.

Caveats

Producer and Creator may repopulate if downstream tools touch the file. Run strip-metadata last in any pipeline.
Embedded fonts and form metadata are not stripped — this skill targets identifying info only.

Output

Metadata-stripped PDF. Original preserved.
