Extract text from PlayStation system updates (PUP)
To convert PUP system updates to another format, you need PlayStation OS or other System software.
To convert other file formats to the "Firmware Update File" file type, you need software like PlayStation OS or a similar tool.
A .PUP file is primarily a Sony PlayStation firmware update package used to upgrade system software on PS3, PS4, and PS5 consoles. It functions as a heavily encrypted archive containing kernel binaries, system modules, and user interface assets. Less commonly, it represents a legacy DotPup installer package for older versions of Puppy Linux.
Officially, these files are applied directly by the PlayStation OS via USB drives. Advanced users often rely on community-developed decryption utilities like PS3 PUP Extractor or pup-unpack to dissect them on a computer. For more background on the operating system, see the Wikipedia article on PlayStation system software.
The main disadvantage of the .PUP format is its proprietary, closed nature. These files are essentially black boxes to standard operating systems. They often exceed 1GB for full system reinstalls and cannot be natively mounted, opened, or inspected by standard archive tools like 7-Zip or WinRAR. This makes verifying the contents or modding incredibly difficult for standard users.
To view what is inside, users typically need to unpack or convert .PUP files into raw BIN data, TAR archives, or standard ZIP files.
Convert.Guru analyzes your PUP file, detects the exact format, and lets you read the text inside.
Users also converted PUB, ISO, PKG, 7Z, TXT, PDF, ZIP, EXE, RAR, BTW, JPG, VU and MINIPSF files.
If you want to convert PUP file to PKG, ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE or ARJ, you can use PlayStation OS or similar software from the "System Software Update Package" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to PUP, try PlayStation OS or another comparable tool in the "System Software Update Package" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PUP converter.
