Internet Speed Test
Measure your download speed, upload speed, and ping latency instantly.
Why Use Internet Speed Test?
Most consumer speed tests are bundled with trackers and autoplay video ads that tank your measured bandwidth. This one runs quickly, uses incompressible random data so compression-aware middleboxes can't inflate the numbers, and shows you separate download, upload, and ping figures you can compare against what your ISP promised. If Zoom calls are stuttering or your deploy is crawling, a 30-second test tells you whether the issue is local networking or somewhere upstream.
How to Use Internet Speed Test
- Click the 'Start Test' button to begin measuring your internet connection.
- The test will automatically run through three phases: ping (latency), download speed, and upload speed.
- Wait for all phases to complete — results are displayed in real-time as each phase finishes.
- Review your results showing ping in milliseconds, and download/upload speeds in Mbps. Click 'Test Again' to re-run.
Worked Examples
Home fiber connection during the day
Gigabit fiber, Wi-Fi 6 laptop, one active user
Download ~780 Mbps · Upload ~820 Mbps · Ping 4 ms
Typical fiber will show upload ≈ download. Ethernet would hit closer to 940 Mbps.
Mobile hotspot on 5G
iPhone tethered, good signal (−85 dBm)
Download ~220 Mbps · Upload ~35 Mbps · Ping 25 ms
5G upload is asymmetric by design. Expect higher ping than fiber.
Troubled connection during a video call
Wi-Fi from far side of house, multiple streams
Download 35 Mbps · Upload 2 Mbps · Ping 140 ms, jitter 60 ms
High ping + low upload = video calls will stutter. Move closer to router or use wired.
About Internet Speed Test
The Internet Speed Test measures your real-world connection performance by testing three key metrics: ping latency (how responsive your connection is), download speed (how fast you can receive data), and upload speed (how fast you can send data). The test works by transferring data between your browser and our server, using adaptive chunk sizing to ensure accurate results whether you're on a slow mobile connection or a high-speed fiber link. Unlike many speed test tools that rely on third-party servers, this test uses our own endpoints for consistent, reliable measurements. Results are displayed in industry-standard units — milliseconds for ping and megabits per second (Mbps) for throughput. The test uses incompressible random data to prevent network compression from inflating results, and runs multiple iterations to reduce variance from momentary network fluctuations.
Troubleshooting & Common Issues
Result is much lower than my plan's advertised speed
ISPs advertise "up to" speeds. Test with a wired Ethernet cable and nothing else using the network to establish a baseline. If wired speed is fine but Wi-Fi is slow, it's a Wi-Fi issue — try a 5 GHz band, move closer to the router, or upgrade from Wi-Fi 4/5 to Wi-Fi 6.
Upload is drastically lower than download
Most residential plans (cable, DSL, 5G) are deliberately asymmetric and offer 5-20% of download as upload. If upload is zero or nearly so, check for a failing modem, a captive-portal network, or a hotspot throttle on your mobile plan.
Ping is high but download/upload look OK
High ping (over 100 ms) on a wired connection usually points to bufferbloat, an overloaded ISP backbone, or a far-away test server. You can reduce bufferbloat by enabling SQM (smart queue management) on your router. For gaming latency specifically, test to a server in your region rather than a continent away.
Test never finishes or hangs at 0 Mbps
Some corporate firewalls and VPN clients block the test endpoints. Disable your VPN or try from a personal hotspot to isolate the issue. If the browser shows no network activity during the test, check for ad blockers or privacy extensions that might be blocking XHR requests to DevPik.
Frequently Asked Questions
How accurate is this speed test?
The test provides a good approximation of your real-world internet speed. It uses multiple iterations with adaptive chunk sizing and incompressible data for accurate measurements. Results may vary slightly between tests due to network congestion, server load, and other factors — this is normal for any speed test.
What is a good internet speed?
For general browsing and streaming, 25 Mbps download is sufficient. For 4K video streaming, aim for 50+ Mbps. For gaming, low ping (under 30ms) matters more than raw speed. For remote work with video calls, 10+ Mbps upload is recommended.
Why is my speed lower than what my ISP advertises?
ISPs advertise 'up to' speeds under ideal conditions. Real-world speeds are affected by Wi-Fi interference, network congestion, distance from the router, the number of connected devices, and time of day. Try testing with a wired Ethernet connection for the most accurate comparison.
What does ping/latency mean?
Ping (or latency) measures the round-trip time for data to travel from your device to the server and back, measured in milliseconds (ms). Lower ping means a more responsive connection. Under 20ms is excellent, 20-50ms is good, 50-100ms is acceptable, and over 100ms may cause noticeable lag in real-time applications.
What's the difference between Mbps and MB/s?
Mbps is megabits per second; MB/s is megabytes per second. One byte is 8 bits, so 100 Mbps ≈ 12.5 MB/s. ISPs advertise in Mbps because the numbers look bigger. File downloads and speed indicators in browsers typically show MB/s.
Does a VPN or proxy affect my speed test results?
Yes — a VPN routes all traffic through a remote server, adding latency and typically reducing throughput by 10-40% depending on the VPN provider, location, and encryption overhead. Disable your VPN to measure your raw ISP speed.
Why does download speed fluctuate between tests?
Internet bandwidth is shared across many users, and conditions change second-to-second based on who's online and what they're doing. Short, ad-hoc tests will bounce around; running several tests at different times of day gives a more reliable picture of your actual baseline.
