Question 1

Which archive formats are supported?

Accepted Answer

Create: ZIP, TAR, TAR.GZ, TAR.XZ. Extract: common archive formats such as ZIP/TAR/TAR.GZ/TAR.XZ (availability depends on browser capabilities and the included libraries).

Question 2

Why is the compression level disabled for TAR/TAR.XZ?

Accepted Answer

TAR is an uncompressed container. TAR.XZ creation uses a different backend, so the simple level slider is not applied there.

Question 3

Can I compress a whole folder and keep subfolders?

Accepted Answer

Yes. Use “Select Folder” (webkitdirectory) or drag a folder in supported browsers; the tool preserves relative paths inside the archive.

Question 4

Will my files be uploaded?

Accepted Answer

No. Compression and extraction run locally in your browser, and files never leave your device.

Question 5

Are there any limitations?

Accepted Answer

Very large archives may be slow or run out of memory depending on your device/browser. For huge datasets, desktop archivers may be faster.
