Zippy

Zippy is a secure way to quickly share files. You can upload files and folders to be zipped up. That zip then gets available for download through a download page. You get the link to it instantly and can access it super quick with the QR code you get shown after zipping. Or you just type the short URL you see in the address bar. If that's not secure enough for you, you can set up a password before zipping up the files. To top all of this off, the zip files get deleted a month after creation since this is meant for quick file transfer, not long term storage.
