QUICK ANSWER
Is it possible to convert PUP to 7Z?
No - not a direct conversion.

A PlayStation Update Package bundles Sony's signed, encrypted console firmware. Its internal segments are encrypted blobs that cannot be meaningfully repackaged into a 7Z archive. Install the .pup directly on the console via USB using Sony's official process.

Why convert PUP to 7Z?

A .pup contains Sony's PlayStation firmware - console OS, system modules, and component firmware - in a signed, encrypted container. 7Z is a general-purpose compressed archive. Repackaging a .pup into 7Z produces a compressed copy of an already-encrypted file; the content remains inaccessible and the console rejects any modified or repackaged update because Sony's signature check fails.

Quality & what to watch

  • To install PlayStation firmware, download the official .pup from Sony's PlayStation support site, copy it to a FAT32 USB drive using the exact folder path Sony specifies, and run the update from the console menu or Safe Mode.
  • PS3 PUP Extractor can pull internal segments from a PS3 .pup for research, but the segments are still encrypted and cannot be archived or used meaningfully.
  • PeaZip or any archiver can compress a .pup into a 7Z file, but the result is a smaller encrypted blob that no console will accept as a firmware update.

Frequently asked questions

Can PeaZip convert a PUP to 7Z?
PeaZip can compress a .pup into a 7Z archive, but the firmware inside remains encrypted - the console cannot install it.
Can I extract files inside a .pup and compress them with 7-Zip?
PS3 PUP Extractor can pull out internal segments, but they are encrypted blobs; compressing them into 7Z does not make them usable.
How do I actually use a PUP file?
Place it on a FAT32 USB drive at the exact path Sony specifies (e.g., /PS4/UPDATE/PS4UPDATE.PUP) and install from the console's System Update menu or Safe Mode.
