Network Speed Tester
Test your internet download speed and latency directly in your browser. No app needed — results in seconds.
Speed test downloads a 5MB file from Cloudflare servers. Results may vary based on server proximity and network conditions.
Free Internet Speed Test — Check Download, Upload & Latency
Slow internet affects everything — video calls freeze, pages load slowly, file transfers stall, and streaming buffers. Knowing your actual internet speeds (versus the speeds your ISP promises) is the first step to diagnosing connectivity issues. This free Network Speed Tester measures your download speed, upload speed, and ping (latency) directly in your browser — no app installation required, results in under 60 seconds.
Click Run Test to begin. The tool sends data packets to and from a test server to measure how quickly your connection can transfer data in both directions, then reports download speed in Mbps, upload speed in Mbps, and latency in milliseconds.
For website owners and SEO professionals, connection speed matters when testing page load times — a slow connection can skew performance test results. Always run speed tests from the same location at different times of day to detect throttling or time-of-day congestion issues with your ISP.
Speed Benchmarks
Basic browsing and email. 5–10 Mbps download is sufficient for general web use and standard definition video.
HD video streaming. Netflix recommends 5 Mbps for HD and 25 Mbps for 4K Ultra HD per stream. Multiple simultaneous streams multiply the requirement.
Video calls. Zoom recommends 1.5 Mbps download/upload for HD video calls. Group calls require 3–4 Mbps. Upload speed matters as much as download.
Online gaming. Latency (ping) is more critical than raw speed for gaming. Under 20ms is excellent. 20–50ms is good. 50–100ms is acceptable. Over 100ms causes noticeable lag.

Frequently Asked Questions
What is a good internet speed?
25+ Mbps download for streaming. 10+ Mbps upload for video calls. Under 50ms ping for gaming.
Download vs upload speed?
Download = data coming to you (streaming, browsing). Upload = data sent from you (calls, uploads).
What is latency/ping?
Round-trip time in ms. Under 20ms is excellent. Over 100ms causes lag in calls and gaming.
