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 | | Use a saved preset | --preset "Web 1x" (explicit flags override) | | Preview without running | --dry-run |

# Convert + resize + custom output
zipic compress --json --level 3 --format webp --width 1920 --output /tmp/out/ /path/photo.png

# Batch a folder
zipic compress --json --format webp --output /tmp/out/ /path/folder

Exit codes: 0 ok / 1 runtime — read error.code from JSON / 64 bad args / 65 Zipic.app not running. pro_required (free tier hits AVIF/JXL output, SVG/APNG/AVIF/TIFF/ICNS/JXL input, daily quota, or >1 preset) returns a structured error with data.purchase_url and data.trial_available — surface those, don't bypass.

For preset / history / dry-run / pro_required schema: reference/cli.md.

When the CLI fails

If zipic isn't on $PATH, or exit 65 persists after one retry:

bash scripts/detect.sh

Read the route field:

| route | Action | | ---------------- | ------ | | cli | Re-run the CLI; it auto-launches Zipic and waits ~8 s for the socket. | | install_cli | CLI binary missing — tell user: Zipic menu bar → "Install zipic CLI". Use Fallback below for now. | | url_scheme | Zipic < 1.9.5, no CLI exists — tell user to upgrade. Use Fallback below. | | halt_no_app | Zipic not installed — suggest brew install --cask zipic or https://zipic.app. | | halt_not_macos | macOS only — suggest ImageMagick / cwebp. |

Fallback: URL Scheme

Only when route is install_cli or url_scheme. URL Scheme is fire-and-forget — no JSON, no exit code. Parameter names differ from the CLI (e.g. --output → directory=, --keep-aspect → ratio=). Load reference/url-scheme.md before constructing the URL — don't translate flags from memory; saveLocation= is a common invented param that doesn't exist (it's directory=). Verify outputs with ls -lh after open.

SVG and presets quick notes

• SVG optimization (Pro, Zipic ≥ 1.9.0): pass .svg files like any other input. Output stays SVG — never set --format on SVG. Level 1–2 conservative, 3–4 balanced, 5–6 may simplify paths visibly.
• Presets (CLI only): zipic preset list --json, zipic preset show "<name>" --json, zipic preset create --name "Web 2x" --level 3 --format webp --width 2400. Free users may keep at most 1 custom preset.
• History (CLI only): zipic list --json --limit 20 / zipic list clear.
