Testen Sie Ihren internet connection speed in seconds. Messen download speed, upload speed, and ping latency with our free online speed test tool. Keine Werbung, sofortige Ergebnisse, pure client-seitig.
This free internet speed test measures your connection's download speed, upload speed, and ping (latency) directly in your browser. No installation, no registration, no ads — just instant results. Use it to verify your ISP's promised speeds, troubleshoot network issues, or find the best server for gaming and streaming.
The test measures how quickly your browser can download and upload data to/from the internet. For download, we fetch test files of known sizes and calculate speed based on time taken. For upload, we send data to a test endpoint. Ping is measured by timing small HTTP requests. Alle Berechnungen happen in Ihrem Durchsuchenr.
Different speed test services use different servers, file sizes, and measurement methods. Ergebniss can also vary based on network congestion, WiFi signal strength, and what other apps are using bandwidth. Run multiple tests at different times for a more accurate picture.
For most households: 25+ Mbps download for HD streaming, 100+ Mbps for 4K and multiple users. For gaming and video calls: under 50ms ping is ideal. Hochladen speed matters for video calls, cloud backups, and live streaming — 10+ Mbps is recommended.
This browser-based test gives a good estimate of your connection speed under current conditions. For the most accurate results, close other apps and browser tabs, use a wired connection if possible, and run the test multiple times.
