Metazap
Metazap is a small CLI tool for recursively stripping metadata from PNG and JPEG images. It optionally creates backups, performs dry runs, and can run oxipng for lossless PNG recompression after the metadata zap.
Features
- Scan a directory tree (recursion can be disabled with
--no-recursive). - Write back in-place or into a separate output directory.
- Optional
.bakbackups before overwriting files. - Dry-run mode that prints the planned work without touching disk.
- Optional
oxipngpass (-z/--optimize) for smaller PNGs.
Build & Install
cargo build --release
# or install globally during development
cargo install --path .
Usage
metazap [OPTIONS] [--input <DIR>] [--output <DIR>]
| Flag | Description |
|---|---|
-i, --input <DIR> |
Directory to scan (defaults to .). |
-o, --output <DIR> |
Optional destination directory; omitted means in-place overwrite. |
-r/--recursive, --no-recursive |
Toggle recursion (defaults to true). |
-d, --dry-run |
Log the planned work without touching files. |
-z, --optimize |
Run oxipng after zapping PNGs for extra savings. |
-b, --backup |
Copy in-place targets to *.bak.<ext> before writing. |
Examples:
# Rewrite the current directory in-place, keeping backups
metazap --backup
# Clean ~/Pictures into ./cleaned without touching the originals
metazap -i ~/Pictures -o ./cleaned
# Inspect exactly what would run before committing
metazap --dry-run --no-recursive
Development
cargo fmtkeeps the style consistent.cargo clippy -- -D warningsis recommended for catching mistakes early.- The current binary does not ship automated tests; consider adding integration tests that feed fixture images through the binary to protect against future regressions.
