Binary to Hex Converter

Q: Is this the same as converting a web color code?

Web colors like #39FF8D are exactly this: three hex byte-pairs (red, green, blue). Paste any two of those pairs as binary here to see the underlying bits.

Q: This converts numbers — how do I convert plain text to hex instead?

Use the Hex Translator , which maps each character of text to its hex byte value, not raw binary numbers.

Convert binary bytes to hexadecimal and back — useful for reading memory dumps, color codes and low-level data.
