About Endianness Tools
The same bytes can represent different numbers depending on the order they're read in. This category reverses byte order between big-endian and little-endian hex representations — a conversion that comes up constantly when reading binary file formats or network data.
Frequently Asked Questions
What's the difference between big-endian and little-endian?
Big-endian stores the most significant byte first; little-endian stores it last. The same 4 bytes represent a different number depending on which order you read them in.
Which endianness does my computer use?
Most desktop and mobile CPUs (x86, ARM in its common mode) are little-endian; network protocols conventionally use big-endian, which is why conversion comes up so often.
