This tool measures your browser's connection to a public speed-test network. It estimates ping with small requests, download speed by receiving test data, and upload speed by sending temporary test data.
Results can vary between runs because Wi-Fi strength, background downloads, VPNs, mobile networks, browser throttling, and hosting location all affect the path your data takes.
Download speed is how quickly data reaches your device. It affects video streaming, app updates, page loading, downloads, and cloud file access.
Upload speed is how quickly your device can send data. It matters for video calls, sending files, live streaming, backups, and online collaboration.
Ping is the delay between your browser and the testing server. Lower latency makes calls, gaming, remote desktops, and interactive apps feel more responsive.
Jitter is variation in latency from one request to the next. A connection can have good speed but still feel unstable if jitter is high.
Speed tests depend on the server being tested. ConverterKey uses a public speed-test network, while other services may choose different nearby servers, use more parallel connections, or route through a different network provider.
Wi-Fi signal, router load, VPNs, browser extensions, background cloud backups, mobile network conditions, and server distance can all change the result. For a fair comparison, run tests from the same device, on the same network, close together in time.
