Upload speed test
Real upload throughput measured live by sending data to a global edge network — the number that decides how fast video calls, cloud backups, photos and live streams leave your device. Runs in your browser, nothing stored.
Sending data up to a global edge server to measure your upload speed…
Upload speed explained
What is upload speed?
Upload speed is how much data your connection can send to the internet per second, in megabits per second (Mbps). It governs video-call quality, cloud backups, sending large files and email attachments, posting photos and video, and live streaming or screen-sharing.
Why upload is usually slower than download
Most home connections are asymmetric — cable and DSL plans devote far more capacity to download than upload, because people typically pull down more than they push up. A 300 Mbps download plan might only upload at 10–20 Mbps. Fiber is often symmetric, with matching upload and download.
What's a good upload speed?
- Under 3 Mbps: slow — calls and large uploads will struggle.
- 3–10 Mbps: OK — solid HD video calls and everyday sharing.
- 10–25 Mbps: good — smooth calls, backups and content uploads.
- 25 Mbps and up: fast — live streaming and heavy upload work with ease.
When upload matters most
If your video calls freeze while you talk, cloud backups crawl, or your game stutters when you're hosting, upload — not download — is usually the bottleneck. Wi-Fi distance, other devices and time-of-day congestion all affect it, so test more than once for a fair read.
