Internet Speed Test Online Free
Measure approximate download speed, upload speed, latency and jitter in your browser using Cloudflare test endpoints.

The test sends temporary sample data to Cloudflare's public speed-test endpoints. Results vary with Wi-Fi quality, browser load, routing and nearby network activity.
About this tool
An internet speed test gives a point-in-time estimate of how quickly your current connection can transfer data and how responsive it feels. FormatForge measures download and upload throughput along with latency and jitter inside the browser. It is useful when troubleshooting slow Wi-Fi, comparing broadband plans, checking mobile hotspots or confirming whether a video call problem may be network related.
Common use cases
- ✓ Check home broadband after installation or a plan upgrade.
- ✓ Compare Wi-Fi performance in different rooms.
- ✓ Test a mobile hotspot before an important meeting.
- ✓ Record approximate speed before contacting an ISP.
How to use it
- Close large downloads, cloud backups and video streams for a cleaner test.
- Select Start Speed Test and keep the browser tab active.
- Review download, upload, ping and jitter together rather than relying on one number.
- Repeat the test at different times or locations when troubleshooting an intermittent issue.
Important interpretation notes
- • A browser test is an estimate, not a guaranteed line-rate measurement.
- • Wi-Fi interference, VPNs, browser extensions and background traffic can change the result.
- • Run more than one test before comparing an ISP plan or reporting a fault.

Frequently asked questions
What is a good internet speed?
The right speed depends on the number of users and activities. Browsing needs less bandwidth than 4K streaming, cloud backup or multiple video calls.
Why is Wi-Fi slower than my broadband plan?
Wireless interference, distance from the router, older devices and shared usage can reduce measured speed.
What is ping?
Ping is the round-trip delay between your browser and the test endpoint. Lower latency generally feels more responsive.
What is jitter?
Jitter is variation between latency samples. High jitter can cause unstable voice and video calls.
Does the test use data?
Yes. The browser downloads and uploads temporary sample data to estimate throughput.
Are results stored?
FormatForge does not save a test history in this version. The result remains in the current browser page.
