This section lists the open-source software that Zipic currently relies on, organized by integration model. We have reorganized this list to accurately reflect the codebase as of Zipic 1.9.3.

Alignment with published release notes — Our public v1.9.0 changelog described enhanced PDF compression through an optional Ghostscript integration (stronger PDF compression with font and stream optimization, plus clearer handling of encrypted PDFs; Pro). Our public v1.9.3 changelog states that PDF and GIF compression now use bundled proprietary pdfoptim and gifoptim, which replace those optional Ghostscript and gifski paths and are not open source. The summary below matches those version descriptions.

1. PNGOptimKit / pngoptim-swift: Native PNG quantization and APNG optimization engine. Replaces the previous external pngquant dependency since Zipic 1.9.0.
   MIT License
2. SVGift 0.3.0: Native SVG optimization engine.
   MIT License
3. FSWatcher: File system monitoring helper.
   MIT License
4. NotchNotification: MacBook notch notification component.
   MIT License
5. GeneralNotification: General-purpose notification component.
   MIT License

Note: Zipic also bundles in-house, closed-source compression components—including our native JPEG encoder, our PDF engine pdfoptim, and our GIF engine gifoptim. Those are proprietary first-party code, are not open source, and are not third-party dependencies, so they are not listed in this open-source inventory. They superseded optional Ghostscript and gifski paths; comparing output with other tools or builds may show differences in size, quality, or speed—that is expected.

1. Sparkle 2.9.0: Software update framework.

2. SettingsAccess 2.1.0: macOS Settings scene access helper.

3. AnyCodable 0.6.7: Type-erased Codable wrapper.
   MIT License
4. keychain-swift 21.0.0: Keychain access helper.

6. Lottie 4.6.0: Animation rendering engine by Airbnb.

7. swift-argument-parser 1.7.0: Command-line argument parser by Apple.

8. webp.swift 1.1.2 / libwebp-ios 1.1.1: WebP codec wrappers around libwebp.

9. jxl-coder-swift 1.9.1: JPEG XL codec wrapper.
   BSD License
10. libavif: AVIF codec library.
    BSD License

Important integration note — Tools in this group are not bundled with Zipic, and they are neither statically nor dynamically linked into Zipic. They are downloaded by the user explicitly from their official upstream into the user's own directory, and Zipic invokes them only as separate operating-system processes via Process (NSTask).

These software are provided "as is", without warranty of any kind. By using this product, you accept the relevant license terms of these software.

Zipic respects the open-source community. PDF and GIF compression uses our proprietary pdfoptim and gifoptim (not open source). Other image workflows combine the permissively licensed libraries above with additional proprietary components where noted. The optional avifenc CLI is used only as described in Group 3. We thank every author and maintainer listed here, and we thank the Ghostscript and gifski projects for their open-source work that supported optional PDF/GIF integration.
