How to Convert Unicode — 3 Easy Steps

1️⃣

Paste Anything

Plain text for encoding, or any Unicode format — \u escapes, decimal codes, U+ hex — for decoding. The auto mode detects it.

2️⃣

Pick a Direction

Choose which format to produce, or leave Auto-detect on decode to turn escapes back into readable text.

3️⃣

Copy & Use

Copy the result with one tap or download as .txt. Nothing is ever uploaded to any server.

Why Use This Unicode Character Converter?

🔀

4 Formats, Both Ways

\u escapes, decimal codes, U+ hex and plain text — encode or decode any direction, one tool.

🪄

Auto-Detect Decode

Paste mixed or unknown formats — the scanner recognizes \u, decimal and hex patterns and decodes them all.

🌍

Full Unicode

Emoji, Hindi, Chinese, Arabic — every plane handled correctly via proper code-point math.

🔒

100% Private

Conversion runs locally in your browser — content and codes never leave your device.

📏

ASCII-Only Option

Keep plain English readable and escape only the special characters — perfect for code strings.

♾️

Unlimited & Free

No size caps, no sign-up, no watermarks. Convert text of any length, as often as you like.

Popular Use Cases

• 🧑‍💻 Decode \u0041-style escapes from JSON, APIs and log files
• 🌍 Find the code point for any emoji or symbol (U+1F30D and friends)
• 📧 Clean HTML numeric entities (A) out of scraped content
• 🧪 Prepare escaped strings for JavaScript, Java or JSON strings
• 🎓 Learn how Unicode represents the world's writing systems
• 🔍 Identify mystery characters in corrupted or imported text

Pro Tips for Unicode Work

• \u0041 = A: JS/Java/JSON escapes use exactly 4 hex digits — this tool pads automatically. Emoji need surrogate pairs, handled seamlessly in both directions.
• Three spellings, one character: A is \u0041 (escape), A (decimal), U+0041 (hex notation) — the auto mode reads all three in one paste.
• ASCII-only encode: ideal before pasting text into code — English stays readable while curly quotes and emoji become safe escapes.
• Decimal vs hex: A and U+0041 are the same code point in different bases — 65 decimal = 41 hex. Both round-trip perfectly here.
• Round-trip test: encode anything, switch to Auto-detect, paste the output — you'll get your original text back exactly.

Frequently Asked Questions

Paste the escapes or codes in the left box, choose "Auto-detect → decode to text", and readable text appears on the right. The scanner recognizes \u0041 escapes, A decimal codes and U+0041 hex — even mixed together in one input.

It's the Unicode escape for the capital letter A — backslash-u followed by the code point in 4 hex digits (0041 hex = 65 decimal = A). This notation is used in JavaScript, Java, JSON and many other systems to represent characters safely in ASCII-only contexts.

Paste the character with a Text→hex mode selected — you'll see its U+ notation (🌍 becomes U+1F30D). The decimal mode shows the same code in base 10, and the escape mode shows the \u form. Three notations, one character.

Some system — an API, database export or editor — escaped non-ASCII characters for safe transport. Paste it here with Auto-detect and the escapes resolve back into the original readable characters, emoji included.

Yes — emoji live beyond the Basic Multilingual Plane and are stored as surrogate pairs. This tool converts pairs to the correct single code point (🌍 → U+1F30D) and back, which naive converters get wrong.

They're the same code points in different bases: A is 65 in decimal and 41 in hex. Decimal with the &#…; notation is what HTML entities use; hex with U+ is the standard Unicode notation. Pick whichever your target system expects.

No. Conversion runs 100% in your browser with JavaScript. Content and code points never leave your device — this page has no server component at all.

Character-level vs byte-level: this tool works with Unicode code points (one character = one code), while our Text to Hex tool works with UTF-8 bytes (one emoji = 4 bytes). Use this for escape sequences and code points, the hex tools for raw byte data.
