Drop one TAR or two hundred. Batch conversion is not a paid feature here.
A tarball from a Linux server or a source release has to be opened by someone on Windows.
TAR is a container with no compression at all, so the files are read out and compressed as they are written into the ZIP. The result is normally much smaller than the TAR it came from.
TAR stores Unix permissions, ownership and symbolic links, and ZIP has no standard way to carry them. Executable bits are lost and symlinks are either dereferenced into copies or dropped, which silently breaks source trees and deployment bundles.
It was designed for tape archives. Compression is applied afterwards by gzip or xz, which is why .tar.gz exists.
No. Re-apply the executable bit after extracting on a Unix system.

ZIP Archive is lossless, so nothing is thrown away in the conversion.
Converted and deleted the moment it finishes. Never written to permanent storage.
