Originally you cannot reindex Magento from admin panel. To perform Magento 2 reindex you need to use PuTTY or another terminal application to run the CLI commands, e.g. command for reindexing:

php bin/magento indexer:reindex

So, most often developers use Magento 2 reindex command line. However, wiith FREE Magento 2 Command Line (CLI) Extension by Magefan you can run CLI commands directly from Magento 2 admin panel.

To reindex Magento 2 from admin panel:

1. Install the Magefan CLI extension to see a new menu item "System > Command Line" to be added to the admin menu.
