Internet Speed Test
Measure your download, upload, and ping speeds. Free, accurate, no signup.
Frequently Asked Questions
How accurate is this speed test?▼
It uses 4 parallel streams to Cloudflare's global edge network and skips the TCP slow-start phase for accurate measurement. Results are typically within 5-10% of Speedtest.net or Fast.com on the same connection.
What does Mbps mean?▼
Mbps stands for megabits per second. 1 byte = 8 bits, so a 100 Mbps connection can download roughly 12.5 MB per second.
What is latency/ping and jitter?▼
Latency (ping) is the round-trip time for a small request, measured in milliseconds. Jitter is the variation in ping over multiple tries. Low ping + low jitter = smooth gaming and video calls.
Why does my result differ from Speedtest.net?▼
Results vary based on test server location, network congestion, time of day, WiFi signal strength, and other devices using your network. This tool measures speed to Cloudflare's nearest edge server.
Is my data safe?▼
Yes. The test only downloads/uploads random bytes from Cloudflare to measure throughput. No personal data is collected or stored.
