Endian Converter

Swap a 16-, 32-, or 64-bit integer between big-endian and little-endian byte order, or interpret a pasted byte sequence in both orders.

This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.

How it works

Enter a value as decimal, 0x hex, 0b binary, or 0o octal and pick a width; the tool shows the byte sequence in big-endian (network) and little-endian order plus the byte-swapped value, with unsigned and two's-complement signed readings. Negative inputs are stored as their two's-complement pattern. The byte view accepts exactly 2, 4, or 8 pasted hex bytes and reads them both ways. All maths use exact big integers; nothing is transmitted.
