Are my files uploaded anywhere?

No. All archiving runs entirely in your browser — your files never leave your device.

What's the difference between .tar and .tar.gz?

A .tar bundles files together without compression. A .tar.gz additionally GZIP-compresses that bundle, so it's smaller. Pick .tar.gz unless you specifically need an uncompressed archive.

01 — Overview

How it works

Bundle multiple files into a single .tar or .tar.gz archive, extract .tar/.tar.gz/.tgz archives (delivered as a .zip so your browser can save them in one download), and gzip or gunzip single files. Everything runs locally in your browser with fflate and an in-house TAR writer — your files never leave your device.

04 — FAQ

Frequently asked

Browsers can only save one file per download. Extracting a TAR yields many files, so they are repackaged into a single .zip you can save and open anywhere.
