Add bleed margins to a PDF for commercial print shops that trim — extends the page size by the bleed amount on each side and shifts content to the new center. Most office digital printing does NOT need this; use only when sending to a print shop. Triggers on phrases like "add bleed", "add 3mm bleed", "prep for trim".
Generate a matching-size cover page with a title (and optional subtitle, author, date) and prepend it to a PDF. Triggers on phrases like "add a cover page", "prepend a title page", "make a cover for this PDF".
Overlay a diagonal text watermark (DRAFT, PRIVATE, CONFIDENTIAL, etc.) at 45° across every page in light red (or user-specified color), at low opacity so body text remains readable. Triggers on phrases like "add a DRAFT watermark", "stamp PRIVATE on every page", "watermark this PDF".
Burn a permanent footer label into every page of a PDF — CLIENT CONFIDENTIAL, PRIVATE, FAMILY DISTRIBUTION, DRAFT, EMBARGOED UNTIL ..., or custom text. User can choose font and size. Renders a PNG preview to verify layout before committing. Triggers on phrases like "add a CONFIDENTIAL footer", "burn in a footer", "stamp 'embargoed until' across the bottom".
Convert a color PDF to grayscale (black-and-white) for monochrome digital printing — saves toner and avoids color-mismatch issues. Triggers on phrases like "convert PDF to grayscale", "make it black and white", "remove color from PDF", "monochrome PDF".
Bundle one or more print-ready PDFs into a single "print job" folder with a manifest, ready to hand to a digital printer or share with collaborators. Triggers on phrases like "create a print job", "bundle these PDFs", "make a job folder for the printer".

Wipe all identifying metadata from a PDF.
<input>-clean.pdf./Title, /Author, /Subject, /Keywords, /Creator, /Producer, /CreationDate, /ModDate.exiftool is the most thorough — it handles both legacy Info dict and XMP.
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
exiftool output.pdf
pdfinfo output.pdf
Both should show empty/default values for Author, Title, Producer, etc.
Producer and Creator may repopulate if downstream tools touch the file. Run strip-metadata last in any pipeline.Metadata-stripped PDF. Original preserved.
