Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

bchunk, also known as BinChunker, is a free, open-source Unix/C command-line utility for converting BIN/CUE and RAW/CUE CD images into ISO data tracks and CDR audio tracks. It is designed for users who need local optical-disc image processing on Linux or macOS, especially when a focused conversion tool is more suitable than a broader disc-image application. The GNU GPL distribution also makes it appropriate for users who value inspectable, freely available software.

Its main strength is specialist conversion coverage. bchunk can write audio tracks as WAV files, handle MODE2/2352 ISO data tracks, and provide both PlayStation extraction and raw MODE2/2352 extraction for MPEG/VCD data. It can also swap the byte order in audio samples. These options make the utility relevant to archival, compatibility, and format-conversion workflows involving mixed data and audio tracks. The narrow feature set keeps the product centered on BIN/CUE and RAW/CUE processing rather than general-purpose disc-image management.

The trade-off is the command-line operating model. Users must be comfortable working with a Unix/C utility instead of a graphical application, and the published platform details center on Linux and macOS. That makes bchunk a strong choice for technically oriented users who need precise BIN/CUE-to-ISO conversion, PlayStation extraction, or audio-track output. Users seeking a graphical workflow or a wider set of disc-image management features should choose a different category tool.
