Files & folders
Compress a single file or an entire directory tree — the structure is preserved.
cervantic
A small, fast
file compressor.
Drag in a file or a folder, pick a format, and get a smaller archive in seconds. Compress and extract 7z, ZIP and tar — on your desktop or in your terminal. Local, open-source, refreshingly simple.
Open source · Local-first · No tracking
What it does
Everything you need to squeeze a file. Nothing you don't.
7z · ZIP · tar
Standard archives any tool can open, with five compression levels.
Compress & extract
It goes both ways. The format is detected automatically on the way out.
Desktop & terminal
A native app and a command-line tool, sharing exactly the same engine.
macOS · Windows · Linux
One small codebase, running natively everywhere.
Safe by design
Extraction can never escape your folder, and nothing ever leaves your machine.
How it's built
01
Open by default
The code is public. Read it, fork it, and trust exactly what it does — no black boxes.
02
Local-first & private
Your files stay on your device. Nothing is tracked, and nothing runs behind your back.
03
Craft over bloat
One thing done well: it starts instantly and feels good to use every day.
Get it
Two ways to use it.
A native desktop window for drag-and-drop, or a single command for scripts and the shell. Same engine, same results.
