Invert hexadecimal byte order (Big-Endian <-> Little-Endian) or reverse raw nibbles.
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.
Input hexadecimal strings.
Choose Byte Endianness Swap or Character Reverse.
Copy reversed hex.
Big-Endian stores most significant bytes first, while Little-Endian stores least significant bytes first (0x1234 becomes 0x3412).
