Self hosted website software for file uploads?

Where I work, I get a lot of large file sent to me often, and I’m tired of people saying the file is too big to send over email. I’m interested in IT and networking amongst other things. so I’m looking for software(s) for Linux that will let me host my own website, where my co workers can log in with a username and password and upload files to a self hosted NAS at my house.

Any suggestions?

Thanks in advance
