What it does
Everything you need to squeeze a file. Nothing you don't.
Files & folders
Compress a single file or a whole directory tree; the structure survives the round-trip.
7z · ZIP · tar
Standard archives any other tool can open, with five levels to trade speed for size.
Compress & extract
It goes both ways: drop an archive back in and the format is detected for you.
Two modes
Compress on this machine, or hand the work to a Collapse server you run yourself when you would rather a stronger one did it. Pick per archive; local is the default.
App & command line
One engine behind a calm window and a terminal command, so clicking and scripting produce the same archive.
Safe extraction
An archive can never write outside the folder you picked, however it was crafted.
