How it works:
The test uploads real test data to a speed-test endpoint and calculates
the transfer rate from the measured upload time.
HOW TO USE
What Is an Upload Speed Test?
An upload speed test measures how quickly your internet connection can send data from your device to an internet server. Upload speed is normally measured in Mbps, or megabits per second.
This free upload speed test performs a real data transfer and calculates your approximate upload throughput based on the amount of data transferred and the measured time.
Why Is Upload Speed Important?
Upload speed matters whenever your device sends files or data to the internet. A faster upload connection can improve activities such as video calls, cloud backups, file sharing, live streaming and uploading photos or videos.
What Is a Good Upload Speed?
The upload speed you need depends on what you do online. Basic browsing requires relatively little upload bandwidth, while video conferencing, cloud backups and live streaming can require considerably more.
- Basic internet use: low upload bandwidth may be sufficient.
- Video calls: a stable upload connection is important.
- Cloud backup: higher upload speed reduces upload time.
- Large file uploads: faster upload speed can save significant time.
- Live streaming: consistent upload performance is particularly important.
How Does the Upload Speed Test Work?
The tool generates test data in your browser and uploads it to a dedicated speed-test endpoint. The tool measures the transfer time and calculates an approximate upload speed in Mbps.
Why Is My Upload Speed Slow?
Slow upload speeds can be caused by network congestion, weak Wi-Fi signal, mobile network conditions, ISP limitations, background uploads, VPN usage, router problems or limitations of the internet plan.
How to Improve Upload Speed
- Move closer to your Wi-Fi router.
- Use a 5 GHz or newer Wi-Fi connection when available.
- Stop unnecessary cloud backups and uploads.
- Disconnect devices that are using significant bandwidth.
- Restart your router if the connection is behaving unusually.
- Test again using a wired connection when possible.
Upload Speed vs Download Speed
Download speed measures how quickly data comes from the internet to your device. Upload speed measures how quickly data travels from your device to the internet. Many consumer internet connections have a much higher download speed than upload speed.
FAQ
Frequently Asked Questions
What is an upload speed test?
An upload speed test measures how quickly your device can send data to an internet server and reports the result in Mbps.
Is this upload speed test free?
Yes. The tool is designed to be free to use in a modern web browser.
How accurate is an online upload speed test?
The result is an estimate of your current connection performance. Wi-Fi conditions, device performance, browser limitations, network congestion and test-server location can affect the result.
What is a good upload speed?
A good upload speed depends on your usage. Video calls, cloud backups, large file uploads and live streaming generally benefit from higher and more stable upload performance.
Why is my upload speed lower than my download speed?
Many broadband and mobile plans are designed with substantially higher download capacity than upload capacity, so a lower upload speed can be normal.
Can I test upload speed on mobile data?
Yes. You can run the test on a mobile connection, although mobile network conditions can cause the result to vary considerably.
