Frequently Asked Questions

Is the Byte Size Converter free to use?
Yes, the Byte Size Converter is completely free with no limitations. Convert between bytes, kilobytes, megabytes, gigabytes, and more as often as you need without registration.
Is my data private when using this tool?
Yes, all byte conversions happen locally in your browser using JavaScript. No data is sent to any server. The calculations are performed entirely on your device.
What is the difference between KB and KiB?
KB (kilobyte) uses the decimal system where 1 KB = 1,000 bytes. KiB (kibibyte) uses the binary system where 1 KiB = 1,024 bytes. The tool supports both standards so you can convert accurately for any context, whether for storage vendors (decimal) or operating systems (binary).
What units can I convert between?
The tool supports bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), and their binary equivalents (KiB, MiB, GiB, TiB, PiB). This covers all common file size and storage capacity units.
Why do file sizes differ between my OS and storage vendor?
Storage vendors use decimal units (1 GB = 1,000,000,000 bytes) while operating systems often use binary units (1 GiB = 1,073,741,824 bytes). A 500 GB drive shows as about 465 GiB in your OS. This tool helps you convert between both systems to understand the actual capacity.
