It would be nice if you had included what Mac you have and what age it is, this determines what OS you can upgrade to.
Upgrading your Mac to a newer OS can only been done through the App Store. Read the following links thoroughly.
How to upgrade to OS X El Capitan - Apple Support
How to upgrade to macOS Sierra - Apple Support
How to upgrade to macOS High Sierra - Apple Support
How to upgrade to macOS Mojave - Apple Support
Please note that if the App Store detects that your Mac can upgrade to a newer OS than El Capitan you will be refused the download of El Capitan.
Make a full back up first, see if any third party apps you use have updates available so they will work in the new OS. also check that any printers/ scanners etc that you use have updated drivers and software so they will continue to function in the new OS.
