A hex encoder rewrites each byte of a string as two hexadecimal digits (0–9 and A–F). It is the compact, copy-safe format used for binary blobs in protocol docs, firmware dumps, color codes, and cryptographic output. EasyRead encodes UTF-8 text into hex in your browser, with optional 0x prefixes per byte, so you can drop the result straight into C, Go, or shell code.
Encode ASCII fields into hex to paste into a packet capture, protocol doc, or unit test fixture that expects byte literals.
Turn configuration strings into hex for flashing tools, serial-port transcripts, and hardware debug logs.
Inspect suspicious strings in hex form to spot non-printable bytes, null terminators, or smuggled encoding.
Produce hex literals for cryptographic test vectors or binary test inputs that need to be checked into source control.
Each ASCII character is one byte, which maps to two hex digits — "A" is 0x41, "0" is 0x30, and so on.
Yes. Pick the 0x-prefixed output if you want literals you can paste directly into C, Go, Rust, or Python source.
Text is encoded as UTF-8 before hex conversion, so a character like "€" becomes three bytes (E2 82 AC).
Use the Hex to Text tool. Paste the hex (with or without spaces and 0x prefixes) and it will decode back to the original string.
No. Encoding happens entirely in your browser. Nothing is sent to a server.
