How to convert text to hexadecimal
Create correctly formatted UTF-8 hex output in three focused steps.
Choose hex formatting
Select a byte separator, optional prefix, and uppercase or lowercase hexadecimal letters.
Export the result
Convert instantly, verify the byte count, then copy the output or download a text file.
Reliable hexadecimal output for real workflows
The converter works at the UTF-8 byte level, making the result useful for debugging, APIs, encoding checks, and data inspection.
UTF-8 encoding
International text and emoji are converted to their actual multibyte UTF-8 sequences.
Developer prefixes
Format bytes as plain pairs, 0x values, escaped \x bytes, or percent-encoded pairs.
Flexible separators
Use spaces, commas, dashes, colons, new lines, or a continuous hex string.
Local conversion
Your input is encoded inside the browser and never uploaded to a processing server.
How text becomes hexadecimal
Computers store text as bytes. UTF-8 assigns one or more bytes to each character, and each byte can be written as two hexadecimal digits from 00 to FF.
ASCII and UTF-8
Common English characters use the same single-byte values in ASCII and UTF-8. For example, uppercase A is decimal 65 and hexadecimal 41. Non-ASCII characters use multiple UTF-8 bytes.
Hex output is not encryption
Hexadecimal is a readable representation of binary data. It does not protect or hide sensitive information because the original text can be decoded easily.
| Text | UTF-8 hex |
|---|---|
| A | 41 |
| Hello | 48 65 6C 6C 6F |
| £ | C2 A3 |
| ✓ | E2 9C 93 |
Text input Hello, World! Space-separated 48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 21 0x prefixed 0x48 0x65 0x6C 0x6C 0x6F Escaped bytes \x48\x65\x6C\x6C\x6F
Text to Hex Converter FAQs
Practical answers about UTF-8, ASCII, byte formatting, emoji, privacy, and decoding.
What does a Text to Hex Converter do?
It encodes text into its UTF-8 bytes and displays every byte as a two-digit hexadecimal value.
Does it support Unicode and emoji?
Yes. The browser TextEncoder handles Unicode input accurately, including accented letters, non-Latin scripts, symbols, and emoji.
Why does one character sometimes produce several hex bytes?
UTF-8 uses one byte for standard ASCII characters and multiple bytes for many international characters and emoji.
What is the difference between 41 and 0x41?
They represent the same hexadecimal byte. The 0x prefix is a common programming notation that identifies a value as hexadecimal.
Can I create a continuous hexadecimal string?
Yes. Choose No separator and No prefix to join every two-digit byte into one continuous value.
Is hexadecimal the same as encryption?
No. Hexadecimal only represents data in base 16 and can be reversed without a key.
Is my input uploaded to the server?
No. Encoding, copying, and downloading happen locally inside your browser.
Can I download the hex output?
Yes. Select Download .txt after converting to save the formatted hexadecimal result.
