Estimate download time
Large files, backups, video exports and software downloads can take longer than expected. Enter a file size and internet speed to estimate the download time in seconds, minutes, hours or days. It is useful for planning uploads, downloads, client transfers and cloud storage work.
Speed versus real transfer time
The calculator uses the speed you enter in Mbps. Real transfers can be slower because of Wi-Fi quality, server limits, network overhead and congestion.
Frequently asked questions
Should I enter Mbps or MBps?
Enter Mbps, which is how most internet plans advertise speed.
Why is the result only an estimate?
Actual transfer speed changes with network conditions and server limits.
Can I use it for uploads?
Yes. Enter your upload speed instead of download speed.
