How to use Convert Big Endian Binary to Little Endian Binary
- 1. Paste the big endian value. Enter a binary number whose length is a whole number of bytes, such as the 16-bit value 0000000100000010. The most significant byte should come first, as big endian stores it.
- 2. Watch the bytes swap. The tool splits the input into 8-bit bytes and reverses their order while keeping the bits inside each byte untouched, so 00000001 00000010 becomes 00000010 00000001.
- 3. Copy the little endian result. Copy the reordered value and use it to interpret memory dumps, craft packets or fix serialization code on a little endian machine.
When to use Convert Big Endian Binary to Little Endian Binary
Convert Big Endian Binary to Little Endian Binary performs the byte swap that trips up anyone moving data between networks and x86 machines. Network protocols transmit most significant byte first, while Intel and most ARM systems store the opposite way, and this tool shows the exact reordering at the bit level.
- Interpreting network captures on a PC. A port number or length field from a Wireshark capture is big endian on the wire. Swap it here to see the value as your little endian debugger will display it in memory.
- Reading file format magic numbers. Formats like JPEG and PNG store multibyte integers big endian. Swapping a header field clarifies why your naive struct read on x86 produced a wildly wrong number.
- Writing cross-platform serializers. Before shipping code that calls htons or bswap, work one example through this tool so your unit test expectations reflect the correct post-swap bytes.
- Learning endianness with concrete examples. Byte order is notoriously slippery to internalize. Swapping a few 16 and 32 bit values and watching the byte blocks move, while bits within them stay put, settles the concept.

Frequently asked questions
Does Convert Big Endian Binary to Little Endian Binary cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
