Frequently Asked Questions

What can be packed?

Any file can be added to the archive, and file names can be bulk-renamed before packing.

Which compression algorithm is used?

Currently ZIP STORE (no compression), so packing is fast — ideal for bulk organization and archiving.

Which entries can be extracted?

Uncompressed (STORE) entries can be extracted; Deflate-compressed entries will show an unsupported notice.

Are files sent to a server?

No. Packing and extraction happen entirely in your browser.
