Text to Hex Converter Online — Char Codes

The tool emits the character code JavaScript itself uses, not UTF-8 bytes. Latin characters fit in two digits, while Cyrillic sits above 255 — П becomes 41f and я becomes 44f. Those are valid character codes but not the bytes a file or network packet would contain, so do not use this output to build binary payloads for non-ASCII text.

Not on the page — a single space is hard-coded as the separator and there is no format switch. Copy the output and strip the spaces with find-and-replace in any editor; the same pass adds 0x prefixes or commas if the result is going into C source.

They are characters too and get codes of their own: 0a for a line feed, 0d for a carriage return, 09 for a tab. Text copied out of a Windows editor shows 0d 0a at every line ending, which makes this a quick way to check what line endings a file actually uses.

Always lowercase — 4a, never 4A — and there is no toggle. Hex casing carries no meaning and every parser accepts either, so if a document format demands uppercase, run the copied result through an uppercase transform.

Both show the code of each character; only the base differs. Hex is four times shorter than binary, which is why dumps and debuggers use it, while binary is clearer when you care about individual bits and masks. A separate Text to Binary page covers that view.

No. The converter runs entirely in the browser, the string never leaves your tab, and nothing is written down. Clear empties both boxes and a reload does the same. There is no conversion history, so copy any result you want to keep.
