📖 Description

UTF-8 (8-bit Unicode Transformation Format) is a variable-length character encoding for Unicode:

Universal Compatibility: Capable of representing every character in the Unicode standard, whether it's Chinese, English, Greek letters, or Emoji.
Space-Efficient: Uses only 1 byte for ASCII characters and typically 3 bytes for Chinese characters, achieving a perfect balance between compatibility and storage efficiency.
Solves Garbled Text: Most garbled text issues (e.g., å¦ä½ å¥½) occur when data that should be decoded as UTF-8 is mistakenly read as GBK or ISO-8859-1. This tool allows you to manually verify the raw byte stream of characters.

This site's tool provides a comprehensive, low-level perspective from characters to bytes:

Converts text into standard UTF-8 byte representations, supporting:
- Hexadecimal Format (Hex): e.g., E4 BD A0 (commonly used for database analysis, Hex editors).
- Percent-encoding Format (Percent-encoding): e.g., %E4%BD%A0 (commonly used for URL transmission).

Instantly restores hexadecimal streams or URL-encoded strings back to their original, readable text—a powerful tool for fixing garbled text.

Displays the underlying 0s and 1s storage state of characters in the computer, aiding in cryptography education and low-level protocol analysis.

Pure Frontend Processing: All encoding/decoding logic is performed locally in your browser in real-time.
Privacy & Security: Your text content (whether it's a snippet of a business contract or a private passphrase) is never uploaded to any server, ensuring 100% data privacy.

Garbled Text	Possible Cause	Solution
你好 -> `ä½ å¥½`	UTF-8 characters mistakenly read as Latin-1	Use this site to re-validate UTF-8 encoding.
你好 -> `浣犲ソ`	UTF-8 characters mistakenly read as GBK/ANSI	Check the source file encoding and use the tool to restore the bytes.
(Blank or Squares)	Font unsupported or encoding truncated	Check if the UTF-8 byte sequence is complete.

Input Content: Enter the original text or the byte sequence to be restored (e.g., \xe4\xbd\xa0) in the input box.
Select Conversion Mode:
- Click "Encode": Get the hexadecimal or URL encoding of the character in UTF-8.
- Click "Decode": Restore the byte stream back to text.
Result Preview: The output box will instantly display the converted result.
One-Click Copy: Quickly save the converted encoding for use in code, configuration files, or database SQL statements.

Perfect Emoji Support: Accurately handles 4-byte complex Emoji characters (e.g., U+1F600), ensuring reliability in modern social app development.
Multi-Format Compatibility: Automatically processes hexadecimal data with 0x, \x, or space separators.
Instant & No Installation Required: Web-based, ready to use, fitting the high-frequency debugging habits of programmers.
Completely Free: No registration required, unlimited usage—an essential tool for solving encoding issues in web development.
