Measures your internet connection's download and upload speed in a few seconds, using test data sent through a server — no separate app required.
For example: Your provider promises 100 Mbps but video keeps buffering — run the test and compare the real speed to what's advertised before calling support.
Who uses it most: Remote workers, IT specialists, everyday users, support specialists
Yes — measurement runs through a test server (api.toolixall.com): downloading sends test data to you, and uploading sends synthetic (not personal) bytes from your browser to measure upload speed.
Speed depends on network congestion, distance to the server, and many other factors — small differences between different tests are normal.
No — only synthetic test data is sent to measure speed; none of your files or personal information are involved in the test.
