Byte Converter

About Byte Converter Tool

This free online byte converter instantly converts between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes. It supports both the binary standard (1 KiB = 1024 bytes, used by operating systems and memory) and the decimal standard (1 KB = 1000 bytes, used by storage manufacturers and network speeds). Understanding this distinction is critical when sizing cloud storage, planning bandwidth, or comparing hardware specifications.

Binary vs Decimal

The binary standard (IEC) uses powers of 1024: 1 KiB = 1024 B, 1 MiB = 1,048,576 B. This is what your operating system reports for RAM and file sizes. The decimal standard (SI) uses powers of 1000: 1 KB = 1000 B, 1 MB = 1,000,000 B. This is what hard drive and SSD manufacturers use. The difference grows with scale — a "1 TB" drive is 931 GiB in binary terms. This tool converts in both standards to eliminate confusion.

Key Benefits

• Dual standards: Binary (1024) and decimal (1000) conversion in one tool
• Full range: Bytes to petabytes with bits included
• Precise output: Up to 6 significant digits for accurate calculations
• Instant results: No server round-trips — everything runs locally
• Completely private: Your data never leaves your device
• No installation: Works in any modern browser

Common Use Cases

DevOps engineers convert between units for disk provisioning (EBS volumes, persistent disks), memory limits (Kubernetes resource requests, Docker memory), and bandwidth calculations. Developers estimate API payload sizes and database storage requirements. System administrators compare reported vs actual storage capacities. Network engineers convert bandwidth units for capacity planning.

Privacy and Security

All conversion happens locally in your browser using simple arithmetic. No data is sent to any server. No cookies, no tracking, no sign-ups required. Free forever.
