Hi there, who has access to your data and what data that is depends on what you post/share and where. To give you a better answer, we would need to know where you want to share them. At least the website you are using knows a lot about you. It can see your ip address, location and a lot more. Here is a blog post from NordVPN with some examples: [https://nordvpn.com/de/blog/what-does-the-internet-know-about-you/ What does the internet know about you, and can you do something about it?] A user that just downloads a file from you usually doesn't have that kind of information though. Depending on the website you are using, they could see things like your username, ip address or location.
