About this tool

This internet speed test measures your connection directly in the browser using real network transfers — no plugin, no app install, no account. It runs parallel download streams, a live-progress upload, sequential ping samples, and an HTTP-level packet-loss approximation, then scores the result against use-case-specific thresholds for gaming, streaming, and video calls.

Every number on this page comes from a live measurement in this session — there's no simulated or cached data. If a metric can't be measured (blocked by CORS, offline, or the endpoint is unreachable), that card shows a clear fallback message instead of a fabricated number.

Key features

• Real download/upload throughput via parallel streams and live XHR upload progress, not a single-request estimate
• Ping measured from 12 sequential requests (first discarded as warmup), with jitter computed as the average absolute difference between consecutive samples
• Honest, clearly labeled HTTP-approximated packet loss — this is not true ICMP packet loss, and the UI says so
• Animated speedometer gauge and a live line graph, both plain canvas, no chart library
• Per-use-case ratings (Gaming, Streaming, 4K Streaming, Video Calls, Large Downloads, Online Meetings) that weight different metrics instead of repeating one overall score six times
• Session test history (clears on refresh), JSON export, clipboard copy, PNG snapshot, and Web Share integration

Why use it

• Get a fast, no-signup read on your actual download, upload, ping, and jitter
• Compare your ISP's advertised speed against what you're actually getting
• Check whether your connection is good enough for gaming, video calls, or 4K streaming specifically — not just a generic score

What is download speed?

Download speed is how fast data can move from the internet to your device, measured in megabits per second (Mbps). It's what determines how quickly pages load, videos buffer, and files finish downloading.

What is upload speed?

Upload speed is how fast data moves from your device out to the internet — sending files, streaming to viewers, or transmitting your video/audio during a call. It's usually lower than download speed on most home connections.

What is ping?

Ping (latency) is the round-trip time, in milliseconds, for a small packet to reach a server and come back. Lower is better — it directly affects how responsive gaming, video calls, and any real-time interaction feel.

What is jitter?

Jitter is the variation in ping from one measurement to the next. Even with a low average ping, high jitter causes stuttering in calls and games because packets arrive at inconsistent intervals.

What is packet loss?

Packet loss is the percentage of data packets that never arrive. True packet loss is measured at the network (ICMP) level, which browsers cannot access — this tool instead reports the fraction of small HTTP requests that failed or timed out as an approximation, clearly labeled as such.

What internet speed is good for gaming?

For gaming, ping and jitter matter far more than raw throughput — most competitive games only need 3-10 Mbps, but ping under 30-40ms and low jitter make the difference between a smooth and a laggy experience.

What speed is recommended for streaming?

Standard HD streaming is comfortable around 5-10 Mbps sustained download. 4K streaming needs considerably more headroom — 25 Mbps or higher sustained — to avoid buffering and quality drops, especially with other devices sharing the connection.

Tips to improve internet speed

• Use a wired Ethernet connection instead of Wi-Fi when testing or during anything speed-sensitive
• Close other devices and applications using bandwidth during the test for an accurate reading
• Restart your router/modem periodically and keep firmware up to date
• Position Wi-Fi routers centrally and away from thick walls or interference sources
• Contact your ISP if repeated tests consistently show far less than your plan's advertised speed
