## Description

PiShrink is a disk image shrinking tool and Linux filesystem optimizer. It reduces the size of disk images to their minimum requirements and configures the filesystem to automatically expand to the full capacity of the storage medium upon the first boot.

The utility provides parallel image compression, utilizing multiple CPU cores to apply gzip or xz compression to large disk image files. It also includes filesystem error repair capabilities to resolve corruption that may otherwise block the shrinking process.

The project covers disk image optimization and management, focusing on reducing storage footprints for portable disk images and virtual drives.
