Can a browser definitively determine legacy file encodings?

Pasted text in browsers is already converted to JavaScript UTF-16 strings. This tool analyzes Unicode properties, byte sizes, and ASCII compatibility rather than binary disk headers.

Why is UTF-8 byte size different from character count?

ASCII characters take 1 byte in UTF-8, while accented letters, non-Latin alphabets, and emojis take 2 to 4 bytes.

Text Encoding Detector

Analyze Unicode code points, ASCII compatibility, and UTF-8 byte characteristics.

How to Use Text Encoding Detector

1Paste your text or string into the analyzer area.
2Review the encoding overview: ASCII compatibility, UTF-8 bytes, and line endings.
3Inspect detected non-ASCII symbols, emojis, and control characters.
4Examine the detailed Unicode code-point breakdown table.

Key Features & Benefits

ASCII compatibility validation
Accurate UTF-8 and UTF-16 byte size calculations
Unicode code point (U+XXXX) and hex representation breakdown
Detection of invisible control characters and emojis
Line ending format detection (CRLF vs LF vs CR)

About Text Encoding Detector

Inspect character encoding characteristics of pasted text. Detect whether strings are pure ASCII, analyze UTF-8 and UTF-16 byte sizes, view Unicode code point tables, and detect invisible control characters.

Unlike traditional web tools that send your personal data, uploaded photos, or sensitive text to remote cloud servers, our Text Encoding Detector operates strictly inside your client browser sandbox. This guarantees high processing speeds without network throttling, and ensures your data privacy is completely preserved.

Multi-Byte Unicode Content Detected

Browser client-side detection evaluates UTF-8 byte representation, ASCII compatibility, and Unicode code points. Definitive legacy file encoding (e.g. ISO-8859-1 vs Windows-1252) requires byte-level binary streams, but UTF-8 is the universal standard.
