Free Text to Hex
Hexadecimal is the lingua franca of low-level computing. This free tool encodes your text as hex bytes — UTF-8 safe — with space, colon or continuous separators to match whatever format you need.
How to Use the Text to Hex
- Type or paste the text to encode.
- Pick a byte separator.
- Click “Convert to hex”.
- Copy or download the hex.
Features
UTF-8 byte encoding rendered as two-digit hex, with space, colon or no-separator output styles. Reports byte count. Handles the full Unicode range; multi-byte characters naturally produce multiple hex pairs.
Benefits & Use Cases
Developers prepare hex payloads for debugging and protocols. Security learners inspect how text maps to bytes. Embedded engineers format strings for firmware tools. Students explore encodings hands-on.
Tips
Colon-separated hex (“48:69”) matches MAC-address style used by many tools. Continuous hex pastes cleanly into code as string literals. Decode any of these formats back with the Hex to Text tool — it auto-detects separators.
