Internet download time calculator

Pick a file or type its size, add your speed, and see how long the download takes.

9 min 57 sec

This is the best case at full speed. Wi-Fi, busy times and the website you download from often make it slower.

MB, GB and Mbps

File sizes are in bytes (MB, GB) but broadband speeds are in bits (Mbps). There are 8 bits in a byte, so a 100 Mbps line downloads about 12.5 MB each second.

Don't know your speed?

Run our free speed test first, then put your download figure in the box above.

Results are estimates to help you decide. Your calculations stay on your device — we don't save them.
