About this Binary Hex Converter

Binary Hex Converter translates among binary, decimal, hexadecimal, and octal so students learn place value and developers debug bitmasks, color channels, and memory dumps. Paste a value, choose the source base, and read equivalents in the other bases without mental long division. Firmware engineers check flag bits; web developers relate hex color digits to component values; teachers generate practice conversions. Invalid digits for a chosen base should be corrected before trusting the result. Conversion is client-side—useful when teaching from a shared screen without uploading student worksheets. For cryptographic digests you need a hash generator; this tool is about positional number bases, not hashing algorithms. Annotate which endianness a dump uses when converting multi-byte hardware registers. Group binary by nibbles when teaching to mirror hexadecimal digit boundaries.

How to use

  1. 1Enter the value in its current number base.
  2. 2Select the source base (binary, octal, decimal, or hexadecimal).
  3. 3Convert to view equivalents in the other bases.
  4. 4Double-check digit validity for the selected base (for example, no “G” in hex).
  5. 5Copy the representation you need into notes or code.

Frequently asked questions

Does hexadecimal accept letters A–F?
Yes. Digits 0–9 and A–F (case usually insensitive) represent values 10–15.
Is leading-zero binary preserved?
Numeric value matters more than decorative leading zeros; pad manually if a fixed width is required.
Can I convert fractional bases?
This tool focuses on integer conversions across common bases.
Why did my binary input fail?
Only 0 and 1 are valid binary digits. Remove spaces or other characters.
How does this relate to hex colors?
Six-digit hex colors are hex pairs for red, green, and blue channel values.
