Frequently asked questions

Is this Internet Speed Test accurate?

The tool estimates speed using in-browser timing and streaming where supported. Results vary by your network and browser permissions. For best confidence, run the test multiple times.

What is a good internet speed?

For a single user, 25 Mbps handles HD streaming and browsing comfortably. Households with multiple devices, 4K streaming, gaming, or video calls benefit from 100 Mbps or more. For latency, under 50 ms is good and under 20 ms is excellent for gaming and calls.

What are ping and jitter?

Ping (latency) is the round-trip time for data to reach a server and back, measured in milliseconds — lower is better. Jitter is the variation between those ping times; low jitter means a stable connection, which matters for video calls and online gaming.

Can I download results as PDF?

PDF export uses your browser print-to-PDF. You can also download results as an image (PNG).

How to test your internet speed

  1. Click “Start Test.” Close other heavy downloads or streams first for the most accurate reading.
  2. Ping & latency are measured first, sending small requests to gauge response time and jitter.
  3. Download speed is measured next — watch the live gauge climb as data streams to your device.
  4. Upload speed is measured last by timing test data sent from your device.
  5. Review, save or share your results. Each test is stored locally so you can compare over time.

About this internet speed test

This free internet speed test measures the real performance of your WiFi or broadband connection directly in your browser — no app, plugin, or sign-up required. In about 20 seconds you get four key numbers: download speed and upload speed in megabits per second (Mbps), plus ping (latency) and jitter in milliseconds (ms).

Download speed reflects how fast you can pull data from the internet — it affects streaming, loading pages, and downloading files. Upload speed matters when you send data out, such as video calls, cloud backups, and posting content. Ping is the round-trip response time to a server, and jitter is how much that response time varies. Low ping and jitter give you a smoother experience for gaming and video conferencing.

For the most reliable result, run the broadband speed checker two or three times, test on WiFi close to your router (or over a wired connection), and pause other downloads. If your measured speed is far below your internet plan, try restarting your router, switching WiFi bands, or contacting your provider.
