How this test works

Transfer time is calculated from file size in bytes and sustained speed in bits per second, adjusted by the selected efficiency. It is an estimate, not a live network measurement.

TRANSFER TIME TOOL

Download time calculator

Estimate how long a file will take to download using its size, your sustained download speed and practical protocol efficiency.

INPUTS
Advanced options (protocols, overhead, parallel connections)

Efficiency accounts for TCP/TLS overhead, congestion, disk speed and remote-server limits. Use 85–95% for a typical stable transfer.
