What does File Size Converter actually do?

The file-size converter switches bytes and KB, MB, GB using decimal (1000) or binary (1024) steps. It does not inspect a real file. A “MB” from a vendor may be either unit; the tool converts the number you type.

When should I use File Size Converter?

Use it when a limit is documented in MB and your code speaks bytes.

When should I not use File Size Converter?

Do not assume 1 MB means 1024×1024 unless the source says MiB or 1024.

What does File Size Converter not do?

You supply the number. Nothing is read from disk here. Decimal and binary units are different results. Pick the one the spec uses.
