How to use Convert Little Endian Hex to Big Endian Hex
- 1. Paste the little-endian hex value. Enter a hex byte sequence stored in little-endian order, such as bytes read directly from an x86 memory dump or a file format that stores multi-byte fields byte-reversed.
- 2. Review the byte order flip. The tool reverses the byte order, not the digit order within each byte, turning a value like 78563412 into its big-endian equivalent 12345678.
- 3. Copy the big-endian result. Copy the reordered hex value into documentation, a network protocol field or code that expects big-endian (network byte order) values.
When to use Convert Little Endian Hex to Big Endian Hex
Convert Little Endian Hex to Big Endian Hex reverses the byte order of a hex value read from a little-endian source. It matters whenever bytes captured from an x86 system, a binary file format or memory dump need to be compared against or transmitted in network byte order.
- Interpreting a binary file's header field. A file format spec documents a multi-byte field in big-endian terms, but your hex editor shows the raw little-endian bytes as stored on an x86 machine.
- Preparing a value for a network protocol. You have a 32-bit integer as little-endian hex bytes from local memory and need it in big-endian order before placing it into a network packet field.
- Debugging a cross-platform serialization bug. Two systems disagree on a numeric field's value, and converting the little-endian bytes to big-endian reveals whether a byte-order mismatch is the actual cause.
