Firefox Send

https://send.firefox.com/

The venerable Mozilla browser Firefox has lent its name to a number of extra apps and services lately, including Firefox Send.
It's blissfully easy to use —with or without- the Firefox browser
— and lets you share files up to a total size of 2.5TB, free of charge.
- 1 TB with NO LOGIN  -OR-  2.5 TB WITH LOGIN

You get a stack of useful options here too.
END-TO-END ENCRYPTION
Download links can be set to expire after a certain number of downloads or amount of time,
and if you want an extra layer of security, you can password-protect them as well,
so that someone else needs both the link and the password to get at the file.

It basically lets you drag-and-drop right in your browser, ANY BROWSER,
without any need to install additional software or sign up for an extra service.
You can keep an eye on when your shared files are accessed too,
and the link can be revoked at any time.
