A BIN file has no headers, no checksums, no metadata, and no compression. It is pure machine code or data, starting at a specific memory offset. Its simplicity is its strength: it is universal and can be written directly to a chip using a programmer.
Converting files to a .pac file is a common task when building firmware for Spreadtrum (SPD) or Unisoc-based mobile devices. The .pac format acts as a container for various partition images (like boot.bin , system.bin , or recovery.img ).
