Base Converter (2 · 10 · 16)

A focused base converter for developers. Paste a value in binary, decimal, or hex, and Birdor keeps all three in sync using BigInt, then shows the underlying bytes in both big-endian and little-endian order.

Binary (base 2)

Grouped in 4-bit chunks. Spaces and underscores are ignored.

Decimal (base 10)

Arbitrary-size integer via BigInt.

Hexadecimal (base 16)

Accepted: 0xFFEE, FF EE, ff_ee

Byte order view

Inspect big-endian and little-endian byte sequences.

Big-endian

Little-endian

Sign is preserved separately. Pad or truncate bytes when working with fixed-width integers.

Tip: Paste a raw hex dump like FF EE DD CC into the hex field to inspect all representations at once.
