Unicode Converter

Unicode Converter

Unicode Converter transforms text into Unicode code points, escape sequences, and HTML entities directly in your browser. Six conversion modes live in a single workspace: text to Unicode, Unicode to text, Unicode escape, Unicode unescape, to HTML entities, and from HTML entities. Input text by typing or pasting, or load a file directly from your computer. An interactive character inspector between the panels reveals the code point, UTF-8 bytes, UTF-16 encoding, and Unicode block for every character. Since everything runs locally, your data never leaves your device.

Online Unicode Converter with Character Inspector

A three-column layout keeps everything visible at once: your text input on the left, converted output on the right, and an interactive character inspector in the center. As you type or paste, each character appears as a clickable tile showing the glyph and its hex code point. Clicking a tile opens a detailed breakdown covering the full code point, decimal value, UTF-8 byte sequence, UTF-16 encoding, Unicode block name, HTML entity, and escape sequence. That level of per-character detail is invaluable when you are tracking down encoding bugs, auditing multilingual content, or confirming that special characters survive transmission across systems.

Upload Text Files for Unicode Conversion

Load any text file into the workspace by clicking the Upload button or dragging it directly onto the input panel. Supported formats include .txt, .html, .htm, .json, .csv, and .xml. Once the file loads, conversion kicks in immediately based on your active mode.

Real-Time Conversion with Instant Results

Results appear the instant you type, paste, or modify the input. No button to click, no delay to wait through. The three-panel layout keeps input, character inspector, and output visible simultaneously, so you can compare values at a glance without scrolling or switching views.

Convert Between Unicode Formats for Any Programming Language

Beyond plain code points, the converter handles escape sequences and HTML entities used across programming languages and web development. Unicode Escape produces \uXXXX sequences compatible with JavaScript, Java, C#, Python, and JSON. Characters outside the Basic Multilingual Plane are correctly encoded as UTF-16 surrogate pairs. Unicode Unescape reverses the process, turning escape sequences back into readable text with support for both standard \uXXXX and ES6-style \u{XXXXX} syntax. The HTML entity modes handle decimal (&#NNN;), hexadecimal (&#xHHH;), and named entities like & and ©.

Escape Sequences for JavaScript and JSON

Generating \uXXXX escape sequences lets you safely embed any Unicode character in JavaScript strings, JSON data, and configuration files. Pasting escaped output directly into your code ensures compatibility regardless of the file encoding. Flip to unescape mode and you can instantly preview what any block of escape sequences actually displays as.

HTML Entity Encoding and Decoding

Converting special characters to HTML entities guarantees correct display in web pages across every browser and character encoding setting. ASCII characters pass through unchanged for readability, while everything else becomes a decimal numeric entity. Going the other direction, you can decode numeric, hexadecimal, and the most common named entities back into plain, readable text.

Free Unicode Converter for Developers, Writers, and Linguists

Unicode encoding appears everywhere in software development, from source code and API responses to database records and multilingual web pages. All six conversion modes are ready the moment you open the page, with no installation or account required. Because every operation runs locally via JavaScript, your sensitive text, debug output, and proprietary content never touch a remote server. Whether you are tracking down a character encoding issue, preparing multilingual content for a website, or exploring how different writing systems map to code points, answers are there instantly.

No Signup, No Limits, No Data Collection

Every feature, from file upload to download, is available the moment you arrive. Input of any size is welcome, and no premium tier or account is ever needed. Close the tab and your session data vanishes with it.

Client-Side Processing for Complete Privacy

Conversion happens directly in your browser through native JavaScript APIs, keeping your files, text, and code points entirely on your device. That makes it a safe choice for sensitive material like proprietary source code, authentication tokens, or confidential configuration data.
