Download Time Calculator
Estimate download time for any file size and connection speed — no upload needed.
Estimated time
How long will my download take?
Enter the file size (in B, KB, MB, GB, or TB) and your connection speed (Kbps, Mbps, Gbps, KBps, MBps, or GBps) to get a precise h:mm:ss estimate. All calculation runs in your browser.
Note the unit difference: Mbps means megabits per second; MBps means megabytes per second (8× faster for the same number). ISP speeds are usually quoted in Mbps.
FAQ
What is the difference between Mbps and MBps? Lowercase 'b' means bits; uppercase 'B' means bytes. One byte equals eight bits, so 100 MBps is 800 Mbps.
Is anything uploaded? No — the calculation is entirely local.
