The short answer
Usually, after a check. Might hold something you care about. Look inside before removing it.
What is it?
Compressed archives over 1 GB anywhere in your home folder: .zip, .7z, .rar, .tar, .gz, .tgz, .bz2, .xz and .zst. Many are downloads already expanded next to them; others are backups or exported projects that may be your only copy.
Archives over 1 GB. Often already extracted, but some are your only copy of a backup: open before deleting, or offload.
What happens if you delete it?
Not recreated. If the contents still exist elsewhere, the archive is redundant; if not, deleting it loses them.
How to remove it properly
List the contents without expanding, with unzip -l file.zip or tar -tf file.tar.gz in Terminal, and check the files exist elsewhere. Move redundant archives to the Trash, and copy backup archives to an external drive before removing them.
Better moved to an external drive than deleted.
Before you delete it
Archives named like backups or exports are often the only copy of old projects or photo sets.
