Number Utilities
21 toolsConvert numbers across binary, decimal, hex, octal, IP addresses, floating point, and words.
Tool list
All Numbers Converter
Convert numbers between binary, octal, decimal, and hexadecimal in one place, with bitwise operations and a 16-bit toggle view.
Decimal to Binary
Convert decimal integers into base-2 binary with BigInt precision for register dumps and bitmasks.
Decimal to Octal
Convert decimal numbers to base-8 octal for Unix permissions, escape codes, and legacy formats.
Binary to Decimal
Read what a binary string means in decimal, supporting separators and arbitrary length.
Binary to Hex
Convert binary values into compact uppercase hexadecimal — the natural form for byte-level work.
Binary to Octal
Group binary digits into base-8 octal — useful for permission masks and three-bit groupings.
Hex to Decimal
Decode hexadecimal numbers into base-10 decimal integers with a step-by-step calculation breakdown and full all-formats panel.
Hex to Binary
Expand hex values into nibble-aligned binary, plus signed/unsigned/Base64/float decoding in one workspace.
Hex to ASCII
Decode hex bytes into decimal ASCII codepoints, plus every other format (text, binary, octal, float, Base64) side by side.
Hex to Text
Convert hex bytes back to UTF-8 text with full multibyte support, plus full all-formats panel for inspection.
Hex to Octal
Convert hex into base-8 octal with side-by-side bit, byte, decimal, and Base64 readings.
Hex to Float
Decode hex bytes as IEEE 754 single or double precision floating-point values with sign, exponent, and mantissa context.
Hex to All
One-page hex inspection: decimal, binary, octal, ASCII, text, signed/unsigned widths, Base64, float — all from a single input.
Octal to Decimal
Decode octal numbers into decimal integers — perfect for translating Unix permission codes.
Octal to Binary
Expand octal digits into 3-bit binary groups for permission and embedded register analysis.
Octal to Hex
Convert octal values into hexadecimal when migrating legacy scripts to modern tooling.
Binary to Text
Decode UTF-8 binary byte strings back into readable text, with multibyte and emoji support.
Text to Binary
Encode any UTF-8 text into space-separated 8-bit binary bytes for puzzles and low-level demos.
ASCII to Text
Decode a list of decimal Unicode codepoints into readable text — emoji and CJK supported.
Char to ASCII
Look up the decimal Unicode codepoint of every character in a string for tests and tickets.
Reverse Hex
Reverse the byte order of a hexadecimal string for endianness flips in protocol and file work.
