  2. Type your upload speedThe upload figure from a speed test, in megabits a second.
  3. Choose a marginTen percent suits a wired connection. Use more on Wi-Fi or a busy network.

Getting a good result

Megabits and megabytes

File sizes are in megabytes; connection speeds are in megabits. There are eight bits in a byte, so a 20 megabit connection moves 2.5 megabytes a second. A 2 GB file is 16,000 megabits: 800 seconds at 20 Mbps, a little over 13 minutes.

Use your upload speed

Home connections are sold on their download speed, and upload is usually much slower. Run a speed test and read the upload line. That is the number that decides how long sending a file takes.

Why it takes longer than the sum

Every transfer carries some overhead, speeds dip when others use the connection, and Wi-Fi is slower than its label. The margin option adds for that.

Video upload time calculator: common questions

How long does 1 GB take to upload?

At 10 Mbps, about 13 to 15 minutes. At 50 Mbps, about 3.

Why is my upload slower than my speed test?

The server you are sending to may be the limit, or other devices are sharing your connection. Wired is steadier than Wi-Fi.

Can I make the upload faster?

Make the file smaller. The video compressor can cut a file to a fraction of its size.

Is anything I type sent anywhere?

No. The sum is done by your browser.
