Cyberdrop if you already made an account, right now registrations are closed.
Gofile is solid, don't need to register unless you want to track your uploads.
Wetransfer is solid too, links are temporary though so if you miss it, you're SOL unless you contact OP to re-up
Some others, files.fm, wesendit, filemail (similar to wetransfer), pixeldrain, 1fichier
