What is PKG?

PKG (application/x-pkg) uses lossy compression optimized for macos software installation, package extraction, application repackaging. macOS Installer Package, Apple Flat-Package software distribution archive

What is GZ?

GZ (Gzip) is a compressed file format commonly used on Unix/Linux systems, often compressing single files or TAR archives.

When Should You Use PKG vs GZ?

Use PKG When...

If macos software installation, package extraction, application repackaging is your end goal, PKG is the smart pick. Its widespread compatibility and small footprint make it a universal choice.

Use GZ When...

For unix/linux file compression, web compression, nothing beats GZ. It hits the sweet spot between visual quality and file size, making it the default choice for millions.

PKG vs GZ: Key Differences

  • •PKG and GZ diverge on compression: lossy compression for the source, lossy compression for the target.
  • •Since both PKG and GZ use lossy compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •Alpha channel support: GZ lacks transparency support.
  • •Storage footprint: varies for PKG vs Similar to ZIP compression ratio for GZ.
  • •Use case fit: PKG targets macos software installation, package extraction, application repackaging and GZ targets unix/linux file compression, web compression — your choice depends on which workflow stage you are serving.
