Convert between bytes, KB, MB, GB, TB, and PB. Calculate bandwidth, transfer times, storage needs, and more. 100% free!
Enter a file size value and select your unit. Choose between Binary (1024-based, shown as KiB/MiB/GiB, used by your OS) or Decimal (1000-based, shown as KB/MB/GB, used by drive manufacturers) standards. Results also include bits (Kbit/Mbit/Gbit, always 1000-based) for bandwidth math. Use the tabs for transfer-time estimation, storage planning, and compression analysis.
