This might be paranoid, but if I go to a website that might not be 100% secure, can they tell what is inside my hard drive desktop’s PDF or what is inside my images on my hard drive?



I have a Chromebook and as well as a Windows machine.

Unless you explicitly grant a website—which is secure (HTTPS) or insecure (HTTP)—access to an item on your system that website will not have access to that item on your system.




This might be paranoid, but if I go to a website that might not be 100% secure, can they tell what is inside my hard drive desktop's PDF or what is inside my images on my hard drive?




Unless you explicitly give them access to your hard drive—or documents on your hard drive—then no, an insecure website won’t be able to access anything.



The only concern with a website that “might not be 100% secure” (and I am assuming HTTPS versus plain HTTP) is that when you transmit data back and forth HTTPS is encrypted and HTTP is not encrypted.



The risk then is if you type something into the site via a form and such, if the site is plain HTTP then the data you are transmitting is just clear text that anyone with a packet sniffer has the potential to read. But that is a slim chance at best.



Like if you are on a known public Wi-Fi network then maybe someone is on that network with you and potentially capturing packets and thus could detect what you are typing.



But in general if you are on a secure network at home or elsewhere you are “safe.”



In general, an “insecure” website only matters if you send data to them.
