LocalSend

LocalSend is a powerful open source cross-platform tool that allows you to share files and messages securely without the need for an internet connection. The tool uses HTTPS encryption to ensure your privacy and prevent data theft during transfers. If you are looking for a good file sharing software without the need to use the internet or third party servers, this is a great option to work on a day to day basis.

The interface of this data transfer software is very simple, since it has two distinct functions: sending and receiving files. In order to share your documents with another person you will have to access through this section and choose all the elements you want to share. On the other hand, you will have to click on the second option if you want to receive these files on the device. Whichever option you choose, LocalSend will generate a unique TLS/SSL certificate on each device for each communication, so it always adds an extra layer of security and authentication that will prevent data loss or theft.
