Transparent formula
The page shows the units and assumptions used for every result. It does not hide bytes-versus-bits conversions or pretend an estimate is an exact network promise.
Privacy and safety
All values are processed in JavaScript. URL Cleaner parses text locally and never asks the server to open, resolve or inspect the destination.
Useful limits
Inputs are bounded to keep accidental huge values from freezing a device. Meaningful media identifiers are preserved unless you remove them yourself.
