UPX is an advanced executable file compressor. UPX will typically reduce the file size of programs and DLLs by around 50%-70%, thus reducing disk space, network load times, download times etc. The current version can compress executables for DOS, Linux/ELF (i386, amd64, ppc32) and some other files for different OS. NOTE: This package is based on the UCL library, which is licensed under GPL.

Overlay options:
--overlay=copy copy any extra data attached to the file [default]
--overlay=strip strip any extra data attached to the file [DANGEROUS]
--overlay=skip don't compress a file with an overlay
File system options:
--force-overwrite force overwrite of output files
--link preserve hard links (Unix only) [USE WITH CARE]

Options for dos/exe:
--8086 make compressed exe work on any 8086
--no-reloc put no relocations in to the exe header
Options for dos/sys:
--8086 make compressed sys work on any 8086
Options for ps1/exe:
--8-bit uses 8 bit size compression [default: 32 bit]
--8mib-ram 8 megabyte memory limit [default: 2 MiB]
--boot-only disables client/host transfer compatibility
--no-align don't align to 2048 bytes [enables: --console-run]
Options for watcom/le:
--le produce LE output [default: EXE]
Options for win32/pe, win64/pe & rtm32/pe:
--compress-exports=0 do not compress the export section
--compress-exports=1 compress the export section [default]
--compress-icons=0 do not compress any icons
--compress-icons=1 compress all but the first icon
--compress-icons=2 compress all but the first icon directory [default]
--compress-icons=3 compress all icons
--compress-resources=0 do not compress any resources at all
--keep-resource=list do not compress resources specified by list
--strip-relocs=0 do not strip relocations
--strip-relocs=1 strip relocations [default]
Options for linux/elf:
--preserve-build-id copy .gnu.note.build-id to compressed output
file.. executables to (de)compress
