ICNS Viewer

ICNS Viewer analyzes Apple ICNS icon bundles to enumerate embedded assets, sizes, color depths, and to export assets plus a machine-readable manifest. It helps developers quickly determine which icon sizes are present and whether an ICNS file covers required macOS and iOS resolutions. Conceptually, the tool parses ICNS binary data into a structured catalog and can export per-icon PNGs or a JSON manifest. The core value lies in reducing manual inspection time and ensuring asset completeness across platforms and pipelines. Typical use cases include asset validation during app packaging, QA checks for icon coverage, and preparing assets for versioned builds. Unique value comes from batch processing capability, direct PNG exports for each entry, and a machine-readable summary suitable for build scripts. Core features include: ICNS parsing, size and depth enumeration, per-entry PNG export, and manifest generation; optional batch processing and ZIP export for consolidated delivery. This tool complements asset pipelines by providing deterministic results that improve consistency and speed in icon provisioning for macOS and iOS projects.
