Native on-device image compression with a JSON CLI and an Agent Skill for Mac and Windows.

Zipic is a native image compressor and converter for macOS 13+ and Windows 10+ (Beta). It processes files 100% on-device — no uploads, no cloud, no account.
It handles JPEG, PNG, WebP, HEIC, AVIF, JPEG XL, TIFF, GIF, PDF, SVG and APNG, plus ICNS on macOS and ICO on Windows. Batch conversion, resizing, six quality levels, target-file-size mode, EXIF removal and an identical-resolution before/after preview are built in.
The zipic CLI is made for scripts and AI agents. It returns per-file JSON, uses meaningful exit codes and supports --dry-run, so an agent can inspect the plan before changing files.
Install the official Zipic Skill:
npx skills add okooo5km/Skills4U --skill zipic
Then ask Claude Code, Codex or another agent to compress a folder, convert to WebP, resize to 1920px or hit a target file size.
