Hex ↔ Text is a free encode & crypto tool that runs entirely in your browser — bytes to text and back, any base. No upload, no account, no limits.
Convert text to hexadecimal bytes and back. Going to hex, you can pick the separator (space, none or 0x-prefixed) and uppercase the digits; going back, it tolerates mixed formatting and decodes the bytes as UTF-8 text.
Yes — space-separated, no separator, or 0x-prefixed, with optional uppercase.
Yes. Text is encoded and decoded as UTF-8, so multi-byte characters convert correctly.
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
