Technical Specifications

Formats, parsing rules and limits.

Rule Details
U+XXXX Uppercase hex, minimum 4 digits (U+0041, U+1F389); the universal documentation form
\uXXXX JavaScript/JSON escapes; astral characters emit surrogate pairs (\uD83C\uDF89)
Decimal Space-separated code numbers (65 66); parsed back only in decimal mode
\u{...} Modern brace escapes verbatim per character, any plane
Splitting Surrogate pairs merge into single code points; lone surrogates pass through raw
Invalid input Out-of-range values, lone surrogates and malformed escapes error with position info
Processing location 100% client-side JavaScript in your browser memory; nothing is uploaded
Usage limit None — convert unlimited texts for free, no signup required

Local Device Privacy

Everything runs in your browser with plain JavaScript. Text never leaves your device.

How to Use the Unicode Converter

  1. Type or paste text with Text → Codes selected, or codes with Codes → Text.
  2. Pick the escape format matching your target: docs, JS, numeric APIs or modern syntax.
  3. Read the breakdown table to inspect any character individually.
  4. Click Copy Output or Download .txt to keep the result.
  5. Click Clear to empty both boxes and start over.

Characters Are Numbers Underneath

Every letter you type is a number to the computer: A is 65, รฉ is 233, and party popper is 127881. Unicode assigns each a permanent code point so text survives across languages, platforms and decades. Conversion tools expose those numbers for debugging, escaping and API work.

Characters vs code points vs units

Most characters need one JavaScript storage unit; emoji need two (a surrogate pair) for one code point. Length properties count units, humans count code points — the classic off-by-one source in string bugs. This tool splits correctly and shows all three figures side by side. For byte-level sizes instead, use the Character Counter.

Escapes for every toolchain

Documentation cites U+0041, JavaScript and JSON embed \u0041, numeric systems pass 65, and modern syntax writes \u{41}. Astral characters need care: only the brace form and surrogate pairs survive older parsers. For HTML contexts use the HTML Encoder instead, which emits entities.

Honest limitations

Code points identify characters but not their rendered appearance — combining sequences and font ligatures need richer text engines. Decimal parsing accepts only clean whitespace-separated numbers. For very large pastes of tens of megabytes, live conversion on each keystroke can feel slower on older phones.

Privacy and Client-Side Security

Privacy Guarantee: All conversion occurs locally inside your browser. Your text is never transmitted, stored, or recorded on remote servers.

Many online converters send your pasted text to a server for processing. TinyToolzz takes a different approach: every code point resolves in the page itself with plain JavaScript.

Because nothing is uploaded, there is no waiting, no account, and no copy retained anywhere. Your text exists only in the tab's memory and is discarded when you close the page or click Clear.

Frequently Asked Questions

What is a Unicode code point?
A code point is Unicode's permanent ID number for a character, written U+0041 for the letter A. JavaScript strings store text as UTF-16 units, where everyday characters use one unit and emoji use two (a surrogate pair) for a single code point.
Which escape format should I choose?
U+XXXX suits documentation and debugging, \uXXXX suits JavaScript, JSON and Java source, decimal suits numeric APIs, and \u{...} suits modern JavaScript and Python. All four carry identical information and convert back losslessly.
How are emoji converted?
Emoji resolve to their true code point, so party popper becomes U+1F389 rather than two half values. The \uXXXX format emits the compatible surrogate pair \uD83C\uDF89, while the other formats show the single code point directly.
What happens with invalid codes when converting back?
Values above the Unicode maximum (U+10FFFF), lone surrogates and malformed escapes show a clear error naming the position, and the output freezes on the last valid result. Fix the code and conversion resumes immediately.
Is there a text length limit?
There is no fixed limit. The tool converts documents of several megabytes in memory. Extremely large pastes (tens of megabytes) may respond more slowly because conversion runs on each keystroke.
Is my text uploaded to a server?
No. All conversion happens locally in your browser with JavaScript. Your text is never transmitted, stored or logged anywhere. Closing the tab or clicking Clear removes everything immediately.
