Get UPX for Windows for free. It is a high-performance executable packer that is safe, portable, extensible, and free for a variety of executable formats.
An overview of UPX
It’s not your typical file compressor, either. With the help of this strong tool, programs and Dynamic Link Libraries (DLLs) can be dramatically shrunk by 50%–70%. Many benefits, including quicker downloads, lower storage costs, and shorter network load times, result from this size decrease.
Its extraordinary compression ratio-achieving capability is one of its many strong points. It provides better results than classic Zip compression, which makes it a very useful tool for distribution size optimization. Additionally, it guarantees quick decompression—on contemporary machines, it can achieve speeds of over 500 MB/sec.
Safety and Confirmation
Security and antivirus software can examine compressed programs and guarantee their integrity and security because of its open-source nature.
Amazing Ratio of Compression
Because of its superior compression over Zip, you may efficiently reduce your distribution sizes.
Quick Decompression
Its in-place decompression makes sure that there is no memory overhead and your compressed executables unpack swiftly.
Checksum Upkeep
To guarantee data integrity, it keeps track of internal checksums for both compressed and uncompressed files.
All-encompassing Compatibility
It works with a variety of executable formats, such as Linux executables, DLLs, macOS apps, and Windows programs.
Mobility
Because it was written in portable, endian-neutral C++, it ensures system compatibility.
Adaptability
Free and Open Source: Its modular architecture makes it simple to incorporate additional executable formats and compression methods.
It is provided with full source code and is distributed under the GNU General Public License v2+, giving you the flexibility to use, alter, and distribute it.
System prerequisites
Windows 7 or later
In summary
UPX is a tool that empowers users and developers equally; it’s more than just a file compressor. Its remarkable compression ratios, blazingly quick decompression, and cross-platform compatibility guarantee that the distribution of your program runs more smoothly, quickly, and affordably.
