Braille Translator Guide
A Braille translator converts regular text to Braille patterns and back. Standard literary Braille uses cells of six dots (2×3) to encode letters, numbers, punctuation, and—when enabled—Grade 2 contractions for common words and letter groups.
What is Braille Translator?
The Braille translator helps educators, learners, and accessibility testers preview text in Unicode Braille Patterns (U+2800–U+28FF). It can output Grade 1 (uncontracted) or Grade 2 (contracted) where supported.
How to Use the Braille Translator
- Enter text in your chosen language (supported locales listed on the page).
- Select mode: Grade 1 (uncontracted) or Grade 2 (contracted).
- Translate to generate Braille; copy the output for documents or embossing workflows.
- Toggle markers: number sign, capitalization, and punctuation as needed.
- Reverse translate (Braille → text) to check readability.
Formulas & Methods
- Character mapping: Latin letters a–z map to Braille cells; numbers use the number sign followed by a–j cells.
- Contractions (Grade 2): Apply language-specific rules for common words/letter groups; context matters (word boundaries, affixes).
- Unicode output: Renders using the Braille block; tactile output requires embossing hardware and paper.
Assumptions & limitations
- Contracted Braille varies by language and locale (e.g., UEB vs other standards).
- Automatic contraction may not match all editorial styles; human review recommended.
- Screen readers may read underlying plain text, not tactile dots.
Examples
Example A — Grade 1
Input: Hello → Output (UEB Grade 1): ⠓⠑⠇⠇⠕
Example B — Numbers and caps
NASA 2025 → ⠠⠝⠠⠁⠠⠎⠠⠁ ⠼⠃⠚⠃⠑ (cap and number signs).
| Element | Marker | |---|---| | Capital letter | Capital indicator | | Numbers | Number sign + a–j | | Contractions | Grade 2 rules (optional) |
Pro Tips & Best Practices
- Choose UEB for modern English unless a different standard is required.
- Keep punctuation simple in learning material; introduce contractions gradually.
- When preparing tactile documents, check embosser capabilities and paper weight.
- Provide plain text alongside Braille for screen readers.

FAQ
Q: What is Braille?
A: A tactile writing system using raised dot cells (2×3) that encode letters, numbers, punctuation, and contractions.
Q: What’s the difference between Grade 1 and Grade 2?
A: Grade 1 is letter-for-letter; Grade 2 uses contractions for common words/letter groups to reduce length.
Q: How are numbers represented?
A: A number sign precedes letters a–j to indicate digits 1–0 in literary Braille.
Q: Does capitalization exist in Braille?
A: Yes—there are capitalization indicators for single letters and words.
Q: Will translation be perfect?
A: Contractions depend on language rules and context; automatic translation handles common cases but may need review.
