Internet Speed Test

Measure your download and upload speed, latency, and jitter — right in your browser, with no app and no sign-up.

Overview

This speed test measures your connection's download and upload throughput along with latency and jitter, right in your browser. It opens several parallel streams of random data to saturate the link for an accurate reading, then reports download and upload in Mbit/s and ping and jitter in milliseconds. Because a speed test has to exchange data with a server, this one talks to our own backend rather than any third party — the measurement itself runs in your browser and the only bytes uploaded are random filler, never your files. On very fast connections the result can reflect our server's capacity rather than your line's ceiling.

Key Features

  • Download and upload speed in Mbit/s with a live gauge
  • Latency (HTTP round-trip) and jitter
  • Multiple parallel streams for an accurate saturated measurement
  • Shows your public IP address
  • No app, no account, no tracking
  • Measured against this site's own server — no third-party service

Common Use Cases

  • Checking if you're getting the speed you pay for — Run the test on a wired connection to compare real throughput against your plan's advertised rate.
  • Diagnosing a slow or laggy connection — High ping or jitter points to latency problems that raw bandwidth numbers alone won't reveal.
  • Comparing Wi‑Fi across your home — Test from different rooms to find dead zones and see how much speed you lose away from the router.

How It Works
1

Press Start

The test measures your latency, then saturates your connection with several parallel download and upload streams of random data.

2

Watch the live gauge

Download, upload, ping, and jitter update in real time as each phase runs. The whole test takes well under a minute.

3

Read your results

Download and upload are shown in Mbit/s; ping and jitter in milliseconds. Run it again any time to compare.

Frequently Asked Questions

Is this a real ICMP ping?
No. Browsers can't send raw ICMP packets, so latency here is measured as the HTTP round-trip time to our server. It closely tracks what you'd see from a command-line ping and is what every browser-based speed test reports.

Why is my result lower than my plan's advertised speed?
The test measures throughput to this site's server, so the result can be limited by our server's capacity, the network path, Wi‑Fi, or other devices on your network — not just your line. For a fast connection you may see our server's ceiling rather than yours.

Do you upload my files or track me?
No. The only data sent during the test is random filler generated on the fly to fill the connection — never your files. There's no account and no tracking; results stay on your screen.

Which browser is best for accurate results?
Any modern browser works. The engine automatically tunes the number of streams for Chrome, Firefox, Edge, and Safari to get the most accurate reading it can.
