@unmarkk/cli

Command-line unmark. Removes metadata from files on your machine, and never sends them anywhere.

npm install -g @unmarkk/cli

unmark inspect photo.jpg          # what does this file say about me?
unmark clean photo.jpg            # write photo.cleaned.jpg without it
unmark scan ~/Pictures --quiet    # which files in here are leaking?

No system tools required — no exiftool, no qpdf. Node 20.11+ and nothing else.

Commands

unmark inspect <path...>     Report what a file carries. Changes nothing.
unmark clean   <path...>     Write a cleaned copy.
unmark scan    <dir...>      Walk a directory and list files carrying metadata.

unmark clean report.docx --in-place            # overwrite, keeping a .bak
unmark inspect draft.md --stylometry           # include the writing-style heuristic
cat draft.txt | unmark clean - > clean.txt     # pipe through stdin
unmark scan ~/Documents --json | jq '.files[] | select(.flagged)'

Exit codes: 0 nothing found, 1 metadata found or signals survived a clean, 2 bad input or usage.

Run unmark --help for every option.

Safety

Writes are atomic — a temporary file in the destination directory, flushed, then renamed — so an interrupted run cannot leave a half-written document where the original was. Writes refuse to follow symlinks. --in-place takes a .bak copy before anything is overwritten.
