Convert raw bytes into KB, MB, GB, TB (Base 1000) and KiB, MiB, GiB, TiB (Base 1024).
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Type raw integer bytes (e.g. 1073741824).
Inspect IEC binary (GiB) and SI decimal (GB) values.
Copy humanized string for user-facing file size displays.
1 MB (SI) = 1,000,000 bytes (10^6), while 1 MiB (IEC) = 1,048,576 bytes (2^20).
Manufacturers sell drives measured in SI (1 TB = 10^12 bytes), but Windows displays storage using IEC (TiB).
