FastZipLite
An archiver that opens before you finish clicking.
A 1–3 MB Swift app that hands the work to macOS itself: nine archive formats in, five out, drag and drop, and a Finder extension.

01What's inside
The specifics, with numbers.
The things a general-purpose tool does not do.
01
Nine formats in
ZIP, 7z, TAR, TAR.GZ, TAR.BZ2, TAR.XZ, RAR/RAR5, ISO 9660 and cpio, with the format detected from content.
02
Five formats out
ZIP with AES-256 encryption, TAR, TAR.GZ, TAR.BZ2 and TAR.XZ.
03
No bundled engine
Hands the work to the system's bsdtar (libarchive) and ditto, so the app stays 1–3 MB with zero external dependencies.
04
Built into Finder
A Finder extension, drag and drop, single or multi-select, a progress bar and cancel.
05
No subscription in the menu bar
One window, one job, no account. macOS 13+.
06
Two builds
A 0.3 MB macOS app and a 3.4 MB portable archive; free during launch.
