# Hex/Unicode Converter Convert characters to/from hex (\xXX) and Unicode (\uXXXX) escape sequences > Canonical page: https://elysiatools.com/en/tools/hex-unicode-converter - **Category:** Format Conversion - **Keywords:** hex, unicode, escape, encode, decode, character, string, hex converter, unicode converter ## Overview The Hex/Unicode Converter is a utility tool that converts text characters to and from hexadecimal (\xXX) and Unicode (\uXXXX) escape sequences. It supports encoding and decoding for programming, data serialization, and text processing tasks. ## Inputs - **Input Text** (textarea): Enter text to convert... - **Operation** (select) - **Output Format** (select) ## When to use - When you need to encode text into hex or Unicode escapes for use in code or configuration files. - When you have escaped sequences in logs or data and want to decode them back to readable text. - When working with international characters and require conversion between different escape formats for compatibility. ## How it works - Enter or paste your text into the input textarea. - Select the desired operation: convert to hex, from hex, to Unicode, or from Unicode. - Choose the output format: with prefix, compact, or array. - The tool processes the input and displays the converted text instantly. ## Use cases - Debugging escaped strings in source code or log files to quickly identify issues. - Preparing text data for APIs or systems that require specific escape sequences for proper parsing. - Converting international text to portable escape formats for cross-platform data exchange. ## Frequently asked questions ### What is the difference between hex and Unicode escapes? Hex escapes (\xXX) use two-digit hexadecimal codes for characters, while Unicode escapes (\uXXXX) use four-digit codes to support a broader range of characters. ### Can I convert multiple characters at once? Yes, the tool processes the entire input text, converting all characters according to the selected operation. ### What output formats are available? You can choose prefix format (e.g., \x41), compact format (e.g., 41), or array format for listing multiple values. ### Is there a limit on input length? The tool handles standard text inputs efficiently, but very large texts may impact performance; it's designed for typical use cases. ### How do I use the array format? Array format outputs the converted values as a list, which is useful in programming contexts where you need an array of character codes. ## Related tools - [ASCII85 Converter](https://elysiatools.com/en/tools/ascii85-converter): Encode and decode text to/from ASCII85 format (Adobe version) - [Base32 Converter](https://elysiatools.com/en/tools/base32-converter): Encode and decode text to/from Base32 format with multiple variants - [Base45 Converter](https://elysiatools.com/en/tools/base45-converter): Encode and decode text to/from Base45 format (RFC 9285) - [Base58 Converter](https://elysiatools.com/en/tools/base58-converter): Encode and decode text to/from Base58 format with Bitcoin and Ripple variants - [Base62 Converter](https://elysiatools.com/en/tools/base62-converter): Encode and decode text to/from Base62 format (0-9, A-Z, a-z) - [Base64 Converter](https://elysiatools.com/en/tools/base64-converter): Encode and decode data to/from Base64 format with URL-safe options - [Base91 Converter](https://elysiatools.com/en/tools/base91-converter): Encode and decode text to/from Base91 format (ascii+basE91 algorithm) - [Braille Converter](https://elysiatools.com/en/tools/braille-converter): Convert text to Braille Unicode characters or decode Braille to text ## Samples - [Hex/Unicode Encoding Format Samples](https://elysiatools.com/en/samples/text-hex-unicode-formats): Examples of hex (\xXX) and unicode (\uXXXX) escape sequence encoding formats - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Special Characters Samples](https://elysiatools.com/en/samples/text-special-characters-samples): Sample text files with various special characters, punctuation, and symbols for testing non-alphanumeric character removal ## Related content - [Unicode, Emoji, and Invisible Character Debugging](https://elysiatools.com/en/hubs/unicode-emoji-debugging): Find hidden or confusable Unicode characters, inspect emoji and domain representations, normalize only when justified, and verify the cleaned copy before it reaches search, URLs, forms, or parsers. - [Binary Payload Encoding, Serialization, and Round-Trip Verification](https://elysiatools.com/en/hubs/binary-payload-serialization): Convert structured data between binary serialization formats, text transport encodings, and escaped representations, then verify fields and bytes through a controlled round trip.
