What is a file size converter?
It restates a file size in bytes and in larger units so you can compare a download, a disk spec, or a memory limit.
How to use it
- Choose SI (1000) or IEC (1024).
- Enter a value and the unit you have.
- Read the table of equivalents.
FAQ
Why do two scales exist?
Hard-drive marketing usually uses 1000-based MB/GB. Many operating systems report 1024-based MiB/GiB, sometimes still labelled MB/GB.
Does this upload a file?
No. You type a number. Nothing is uploaded.
