Speedtest is a free internet speed test that runs right in your browser. Hit Go and in a few seconds you'll know how fast your connection really is.
What a speed test measures
- Download — how fast data reaches you (Mbps); matters most for streaming and downloads.
- Upload — how fast you send data; needed for video calls, livestreams and backups.
- Ping — latency in ms; the lower, the smoother for gaming.
- Jitter — how much ping varies; low jitter means a stable line.
Test WiFi, mobile or broadband
Run the test on a phone or computer, over WiFi or mobile data. Check your WiFi speed, or see whether your ISP actually delivers the bandwidth you pay for.
Get an accurate result
Close other tabs and downloads, move closer to your router or plug in with a cable, then press Go. Run it a few times at different hours for a realistic picture.
It's completely free — no login, no install. People often type it as speedtesst, speetest, speedtes or speed test, but it all means the same thing: checking your internet speed.
