All tests
Each test has its own page with a short report. The page states what was measured and what the result cannot show. Speed tests are first, then IP, privacy, DNS and calculators.
Speed and latency
- Internet Speed TestTest my internet speed: the report shows download, upload, latency and jitter to a test server, and what the line is likely enough for.
- Download Speed TestTest download speed on its own: one number in Mbit/s and the idle latency. It sends less data than the full test, so it suits a data limit.
- Upload Speed TestCheck upload speed in Mbit/s and see how latency changes while data is sent. Upload matters for video calls, live streams and cloud backups.
- Ping TestCheck ping online: latency and jitter in ms to a test server. It uses web requests, not ICMP, so a terminal ping can show other numbers.
- Bufferbloat TestLatency rises when downloading? This bufferbloat test compares latency on an idle line with latency during download and during upload.
- Internet Stability TestConnection stability test: up to five short runs in a row show how far download speed and latency differ from run to run.
- Live Ping MonitorPing graph over time: latency and jitter to a test server are recorded every second, and large jumps are marked on the chart.
- Wi‑Fi vs Ethernet TestIs Ethernet faster than Wi-Fi? Test on both, label each run, and see download, upload and latency for the two connections in one table.
IP and network
- What Is My IPCheck my IP address: your public IP, its version, and the network that announces it, shown as a website receives them from you.
- IPv6 TestAm I using IPv6? The test checks IPv4 and IPv6 separately and shows which one your browser prefers when both work.
- Is My Internet Working?Is my internet down? Three checks run in order: the device is online, domain names resolve, and a remote server answers.
- Subnet CalculatorCIDR calculator: from an address and a prefix such as /24 you get the subnet mask, first and last host, number of hosts and wildcard mask.
- Wi‑Fi QR Code GeneratorQR code for Wi-Fi password: enter the network name and password, get a code that guests scan to join, and create a strong password if needed.
Privacy
- WebRTC Leak TestWebRTC IP leak test: see which IP addresses the browser reports through WebRTC, for example while a VPN is on. A public STUN server is asked.
- VPN TestIs my VPN working? The report compares the country of your IP, the browser time zone and language, and the addresses WebRTC reports.
- What Are My HTTP HeadersHTTP headers viewer: a list of the header fields your browser attaches to each request, from the user agent to the accepted languages.
DNS
Planning
- How Much Internet Speed Do I Need?What is a good internet speed? Choose video calls, streaming or games and see the usual download, upload and latency needs, with sources.
- Download Time CalculatorHow long to download a file? Enter the file size and your line speed and read the time in hours, minutes and seconds. MB and MiB are kept apart.
- Mbps to MB/s ConverterMegabits to megabytes per second: convert Mbit/s, MB/s, Gbit/s and other rates. Decimal MB and binary MiB are listed separately.
- PPI CalculatorPixel density calculator: enter the resolution and the screen diagonal to get PPI, dot pitch and the physical width and height.
- Bandwidth CalculatorHow much bandwidth do I need? Count the people and devices in use at once and get the download and upload speed to ask your provider for.
- Data Usage CalculatorHow much data do I use per month? Enter daily hours for streaming, calls, games and browsing and get an estimate in GB.
- Streaming Bitrate CalculatorUpload speed for streaming: choose resolution and frame rate to get a usual video bitrate and the upload speed that fits it.
- Video File Size CalculatorVideo bitrate calculator: get the file size for a bitrate and length, or the bitrate that fits a size limit. Result in MB and GB.
