Convert text to lowercase hexadecimal UTF-8 bytes separated by spaces. Inspect non-ASCII characters correctly and copy or download the byte-pair output.
Inspect the bytes used to encode a text value in UTF-8. The result shows two hexadecimal digits for each byte, separated by spaces. It is not a list of Unicode code points, a colour converter or a way to encrypt a message.
Your input stays on this device for this operation. We don’t upload or store it.

Characters outside ASCII can produce multiple output bytes.
Each byte is rendered as two lowercase hex digits with spaces between bytes.
Copy the byte pairs or save them as a TXT file.
Paste the exact value into Source text. Spaces and newlines are part of the input and are encoded too.
Press Process to generate the lowercase, space-separated UTF-8 hex representation.
Copy the output or download text-to-hex.txt. Use HEX to Text if you want to check the decoded text.
Input: text, up to 100,000 JavaScript string units. Output: lowercase space-separated UTF-8 hex bytes; TXT export.
Hi becomes 48 69. The text é becomes c3 a9, illustrating why UTF-8 byte output differs from a simple one-byte character table.
UTF-8 uses multiple bytes for many characters. For example, é is encoded as c3 a9, not as one byte e9.
No. It shows an encoding's bytes. A code-point notation such as U+00E9 describes a different representation of é.
No. Source whitespace is encoded. An ordinary space becomes byte 20; remove unwanted source spaces before processing.
