Zipic
Native macOS image compression, 100% local. Drive it via the zipic CLI; URL Scheme is a fallback only when the CLI binary isn't installed.
Compress
zipic compress --json [flags] <files-or-dirs>...
--json is required — it surfaces per-file output_bytes / saved_pct and lets you map exit code to the failure mode. Pass directories directly; Zipic walks them recursively.
| Need | Flag |
|---|---|
| Compression level (1–6) | --level 3 (1 = best quality, 6 = smallest) |
| Convert format | --format webp (also jpeg|png|avif|heic|jxl) |
| Cap width | --width 1920 (aspect kept by default) |
| Custom output directory | --output /tmp/out/ (auto-sets --location custom) |
| Mirror source tree | --keep-hierarchy |
