Binary to Hex Online

Updated 2026-07-09

Convert binary to hexadecimal online for free. Paste a binary value — spaces between groups are fine — and SnapTools shows its hex representation instantly, in your browser. Nothing you enter is uploaded.

Long binary strings are hard to read, so they are almost always written in hex, where every four bits collapse into a single digit. This converter does that grouping for you, turning a wall of ones and zeros into a compact hex value ready to copy — handy for byte values, colours, and low-level debugging. For every base at once, use the Number Base Converter.

// how to use

1 Paste or type a binary value into the input (spaces between groups are fine).
2 SnapTools converts it to hexadecimal as you type.
3 Copy the hex result, or open the Number Base Converter for all bases at once.

No. The conversion runs entirely in your browser, so nothing you enter leaves your machine.

Group the bits into fours from the right, then replace each group with its hex digit — 1111 is F, 1010 is A. Pad the leftmost group with zeros if needed. This tool does the grouping for you.

Hex letters are shown in upper case (FF, not ff), the most common convention for byte and colour values. Either case means the same number.

Yes. Spaces separating your binary groups are ignored, so you can paste readable byte-spaced binary straight in.

Binary only uses the digits 0 and 1. Any other character is flagged so you can fix it instead of getting a wrong result.
