Pkg to ISO Converter

About This Tool

This tool estimates how a disk image or installer package will change in size when converting between PKG, ISO and IMG formats. It uses an input-driven model to reflect typical container overhead and optional compression. By supplying source_format, target_format, and source_size_mb you receive a target_size_mb estimate along with optional timing and status data. The model supports simple rules for common format pairs and allows compression to reduce target size using a user-specified ratio. This helps packaging teams forecast storage, transfer time, and bandwidth requirements during release planning. The tool is designed for build engineers, release managers, and QA who need quick, reproducible estimates without performing a full conversion. The core differentiator is the explicit, configurable overhead and compression model, plus explicit handling of unit choices (MB vs MiB) and clear edge-case behavior. Typical use cases include estimating the impact of switching from PKG to ISO for distribution or determining whether a compressed ISO will meet storage constraints before a build completes. The approach emphasizes transparency: all inputs, formulae, and default values are documented, and users can adjust overhead factors to reflect their environment. Core features include source/target format validation, optional compression, overhead-based sizing, and time estimation.
