Braille Text Generator

Convert any text into Grade 1 (uncontracted) English Braille using the official Unicode Braille block. The tool renders each character as a large 2×3 dot cell so you can see exactly which dots are raised, plus a per-character map showing the source letter alongside its Braille glyph. Useful for accessibility prototyping, classroom demos, signage proofs, and anyone learning the alphabet.

使用方法

Type or paste the text you want to translate into the input field.
トグル Capital Letter Indicator on or off to control whether uppercase letters are prefixed with the ⠠ marker.
トグル Number Indicator on or off to control whether digit runs are prefixed with the ⠼ marker.
Watch the Braille Unicode output update in real time, alongside a visual dot-cell preview and a character-by-character mapping table.
Copy the Unicode output to your clipboard, or download it as a plain .txt file for embedding in documents and apps.

機能

Grade 1 Braille translation – Letter-for-letter conversion across A-Z, 0-9, and common punctuation using Unicode Braille (U+2800–U+28FF).
Large visual dot cells – Each character is drawn as a 2×3 grid of dots so raised positions are unmistakably clear.
Per-character map – A scannable grid pairs every source character with its Braille glyph and a short label.
Number indicator support – Digit runs are correctly prefixed with the ⠼ number indicator so they are not misread as letters A-J.
Capital indicator support – Uppercase letters can be marked with the ⠠ capital indicator (optional toggle).
コピーとダウンロード – One-click copy of the Unicode output or download as a .txt file.
ブラウザ内で完全に動作 – No text leaves your device; nothing is uploaded.

 よくある質問

How does Braille encode letters as dots?

Each Braille cell contains six dot positions arranged in a 2x3 grid (numbered 1-3 in the left column, 4-6 in the right). Different combinations of raised dots represent different letters, numbers, and punctuation, giving 64 possible patterns including the blank cell.
What is the difference between Grade 1 and Grade 2 Braille?

Grade 1 (uncontracted) Braille spells every word out letter-by-letter, making it ideal for beginners and exact transcription. Grade 2 (contracted) Braille uses shorthand contractions and short-form words to reduce space and reading time, and is the standard for published books.
Why do Braille digits look the same as letters A through J?

The first ten letters of the alphabet share their dot patterns with the digits 1-9 and 0. A preceding number indicator (dots 3-4-5-6, the ⠼ glyph) tells the reader that the following cells should be interpreted as digits until a space or letter sign resets the run.
How is a capital letter marked in Braille?

A capital letter indicator (dot 6, the ⠠ glyph) is placed immediately before the letter to mark it as uppercase. Doubling the indicator (⠠⠠) signals that an entire word should be read in capitals.
What is the Unicode Braille Patterns block?

Unicode reserves the block U+2800 through U+28FF for Braille. Each codepoint maps to one of the 256 possible 8-dot Braille cells; the lower 64 codepoints cover the 6-dot patterns used in classic literary Braille. The bits of (codepoint - 0x2800) correspond to dots 1 through 8.
