Hexadecimal encoding represents each byte as two hex digits. The digits range from 0 to 9 and A to F. Each pair converts to one byte, which then maps to a character using UTF-8 encoding.
Developers use hex strings when debugging network protocols, analyzing binary files, or processing encoded data from databases. The format compresses binary data into readable text without losing information.
This converter handles multiple input formats. Plain hex strings like 48656C6C6F work alongside spaced formats like 48 65 6C 6C 6F. Prefixes like 0x48 get stripped automatically when enabled. Auto-detection cleans invalid characters and processes valid hex pairs.
Paste hexadecimal values in any supported format. Spaces and prefixes are optional.
The tool removes spaces, strips prefixes, and filters invalid characters based on your settings.
Each hex pair becomes a byte value. Bytes combine to form the complete data stream.
The byte stream decodes using UTF-8 encoding, producing readable text output.
Hexadecimal uses base-16 numbering. Each digit represents four bits. Two digits form one byte.
Proper handling of international characters, emojis, and special symbols through UTF-8 decoding.
Intelligent format recognition handles mixed inputs, spaces, and prefixes without manual cleanup.
Paste hex data into the input field.
Adjust options for your hex format.

Network debugging requires converting hex dumps from packet captures into readable text. Developers inspect API responses, database blobs, and configuration files stored in hex format. Security analysts decode encoded payloads during forensic investigations.
Reverse engineers convert machine code representations back to text. Data analysts process hex-encoded CSV exports. System administrators decode log entries stored in hexadecimal format.
Hexadecimal encoding maps each byte to two hex digits. The letter A converts to hex 41. The word Hello becomes 48656C6C6F. This compact representation reduces storage while remaining human-readable.
Each hex digit represents four bits. Two digits form eight bits, which equals one byte. Bytes combine to form characters, words, and complete messages. UTF-8 encoding handles multi-byte characters for international text.
Answers to common questions about hexadecimal conversion.
The tool handles plain hex strings like 48656C6C6F, spaced formats like 48 65 6C 6C 6F, and prefixed formats like 0x48 0x65. Auto-detection mode processes mixed formats automatically.
UTF-8 encodes characters using one to four bytes. ASCII characters use one byte. International characters and emojis use multiple bytes. The converter decodes all UTF-8 sequences correctly.
Invalid characters get filtered when auto-detect is enabled. Incomplete byte pairs cause errors. The tool shows clear error messages to help identify problematic hex values.
Yes. Visit our String to Hex Converter page to reverse the conversion. This encodes your text back into hexadecimal format with proper byte representation.
Hexadecimal is more compact than binary. Each hex digit represents four bits. Two hex digits equal one byte. This makes hex easier to read and process than raw binary strings.
Yes. All conversion happens in your browser using JavaScript. No data gets sent to servers. Your hex data stays private and secure.
