All conversion runs locally in your browser. No data is sent to any server.
Unicode Escape, HTML Entity, Code Points, UTF-8 Hex, and Punycode in one tool.
View code point, UTF-8 bytes, and Unicode block for any character.
Handles emoji, CJK, Arabic, Cyrillic, and every Unicode block.
Encode text to Unicode or decode Unicode sequences back to text.
Copy converted results to clipboard instantly.
Yes. It works well for debugging escaped JSON payloads, converting HTML entities back into readable text, and checking Punycode values for internationalized domains before shipping or troubleshooting.
Convert text to Unicode and back online free with FreeToolBox — transform any text into Unicode escape sequences (\u0041), HTML entities (A), Unicode code points (U+0041), UTF-8 hex bytes, or Punycode for internationalized domain names. Essential for web developers, content creators, and anyone working with multilingual text, character encoding, or internationalization (i18n).
The converter supports five encoding modes and includes a character inspector that shows the code point, decimal value, UTF-8 byte representation, and Unicode block for each character. All processing runs entirely in your browser using JavaScript — no data ever leaves your device. Completely free, instant, no account required.
Use Unicode Converter when the issue is character encoding, escaping, or internationalized text. If you are troubleshooting encoded URLs, continue with URL Encoder/Decoder. If you are working with encoded payloads or transport-safe strings, pair it with Base64 Encoder/Decoder.
No-upload workflow: multilingual text, escaped strings, and sensitive content stay in your browser while you inspect and convert them.
Unicode escapes are useful when a system expects escaped strings inside source code, JSON, or configuration files. Plain text is more readable for humans, but escaped output is often safer for transport or debugging exact character values.
Unicode is a standard that assigns each character a unique code point — a catalogue of what exists. UTF-8 is a way of encoding those code points into bytes for storage and transmission. The two are often spoken of as if they were the same thing, but they are not. A text file labeled as UTF-8 is using a particular byte representation of Unicode characters. This distinction explains a lot of confusion: a string can be valid Unicode but be stored or transmitted in a way that a given system does not read correctly.
When a correctly encoded character is read using the wrong encoding, you get the familiar sequence of odd symbols known as mojibake. The most common cause is a mismatch between how a file was saved and how it was opened — a UTF-8 file read as Latin-1, for example. Converting between encodings fixes this only if you know the source encoding; guessing is unreliable. When a conversion produces strange characters, the first thing to question is whether the original was truly in the encoding you assumed.
For almost all new work, UTF-8 is the right default: it covers the entire Unicode range and is the de facto standard on the web. You would only reach for something else for a specific legacy system that requires an older encoding. When you convert between encodings, begin from a known-correct source and verify the result, not just the conversion itself. If you are handling text with characters outside the first 127, always confirm the encoding rather than assuming an ASCII-only file will represent them safely.
