Why so many free tools?
speedtest.it started as a speed test, but your internet connection isn't only measured in Mbps: knowing your public IP, checking an SSL certificate, generating a strong password or converting a file are all part of the same toolbox. That's why we built a collection of tools useful for anyone working with networks, security and development alongside the main test — most of them run entirely in your browser, with no data sent to any server.
