Internet Speed Test — Download, Upload, Ping & Jitter
Test your download speed, upload speed, ping, and jitter directly from your browser. ToolMint also shows your IP address, ISP metadata, server details, and a live gauge while the test runs, using Cloudflare speed test endpoints for the underlying measurements.
Internet Speed Test
Download · Upload · Ping · Jitter
Download
Measures how fast data reaches your device from the internet.
Upload
Measures how fast your device sends data to the internet.
Ping
Round-trip latency — lower is better for gaming & calls.
Privacy
Runs entirely in your browser. Nothing is stored or shared.
Included Internet Speed Test Tools
Ping & Jitter Test
Measures latency across multiple rounds, then calculates jitter from the variation between consecutive ping results.
Download Speed Test
Uses progressive Cloudflare download chunks to estimate your real browser download speed with live progress updates.
Upload Speed Test
Generates random payloads in the browser and measures upload throughput against test endpoints for a realistic upload result.
Connection Details & Gauge
Shows your public IP address, ISP metadata, test server details, and a live SVG speed gauge that updates during each phase.
How to Run the Speed Test
Start the test
Launch the speed test to begin the full sequence of ping, download, and upload checks from your browser.
Wait for each phase
The tool runs ping, download, and upload tests in order, with live progress indicators and gauge feedback during each stage.
Review the metrics
Check your ping, jitter, download speed, and upload speed once the test finishes.
Inspect connection info
Use the built-in IP, ISP, and server information to understand where the test ran and what connection it measured.
Frequently Asked Questions
- What does this internet speed test measure?
- ToolMint's Internet Speed Test measures 4 core metrics: ping, jitter, download speed, and upload speed. It also displays your IP address, ISP details, and the server information used for the test.
- How is download speed measured?
- The tool requests progressive download chunks from Cloudflare speed test endpoints and counts transferred bytes using the browser stream reader API. That lets it estimate throughput in Mbps based on real browser network activity.
- How is upload speed measured?
- The upload test creates random payloads in the browser using crypto.getRandomValues() and measures how quickly they can be sent to the test endpoint. This provides a practical upload throughput estimate.
- What is jitter?
- Jitter is the variation between consecutive ping times. Even if your average ping looks fine, high jitter can cause lag spikes in gaming, video calls, and real-time streaming. The tool calculates jitter after multiple ping rounds.
- Does the test require an app or plugin?
- No. Everything runs directly in your browser using standard web APIs and Cloudflare speed test endpoints. You do not need to install anything to measure your connection.
