Text To Binary

Convert any text or string into its equivalent binary representation (0s and 1s).

The Text to Binary converter translates ASCII characters into their 8-bit binary codes. This tool is great for educational purposes, low-level data viewing, and understanding character encoding basics. Convert text to binary now!

this.errorMessage = '', 3000); return; } const byteArray = new Uint8Array(binaryString.length / 8); for (let i = 0; i < byteArray.length; i++) { const byte = binaryString.substr(i * 8, 8); byteArray[i] = parseInt(byte, 2); // Validate conversion if (isNaN(byteArray[i])) { this.errorMessage = 'Invalid binary data detected. Download aborted.'; setTimeout(() => this.errorMessage = '', 3000); return; } } const blob = new Blob([byteArray], { type: 'application/octet-stream' }); const url = window.URL.createObjectURL(blob); const a = document.createElement('a'); a.href = url; a.download = 'binary-output.bin'; document.body.appendChild(a); a.click(); document.body.removeChild(a); window.URL.revokeObjectURL(url); return; } // For .txt file, save the text representation const content = this.encoded; const filename = 'text-to-binary.txt'; const mimeType = 'text/plain'; const blob = new Blob([content], { type: mimeType }); const url = window.URL.createObjectURL(blob); const a = document.createElement('a'); a.href = url; a.download = filename; document.body.appendChild(a); a.click(); document.body.removeChild(a); window.URL.revokeObjectURL(url); } catch (error) { console.error('Download error:', error); this.errorMessage = 'Failed to download file. Please try again.'; setTimeout(() => this.errorMessage = '', 3000); } } }">

Convert text to UTF-8 binary representation

• Uses standard UTF-8 encoding for all characters (ASCII, emoji, Chinese, Arabic, etc.)

• Each byte is represented as exactly 8 binary digits (0s and 1s)

• Perfect for understanding character encoding and computer science basics

• Multiple output formats: spaced, continuous, or grouped

UTF-8 Byte Breakdown

Each row represents one byte. Multi-byte characters (emoji, Chinese, etc.) span multiple rows.

Byte #	Binary	Decimal	Hex	Character

Text converted to binary successfully! Each character is represented as 8 bits (1 byte).

Usage Tips & Best Practices

Best Uses

• Learning binary and character encoding
• Understanding computer data representation
• Educational computer science projects
• Low-level data inspection and analysis

Good to Know

• Each character = 8 bits (1 byte)
• ASCII characters: 0-127 (7 bits + padding)
• Extended ASCII: 128-255 (full 8 bits)
• Use Character Breakdown for details

UTF-8 Encoding: This tool properly handles all Unicode characters including emojis, Chinese, Arabic, and special symbols using standard UTF-8 byte encoding.

How it works: Each character is converted to UTF-8 bytes (1-4 bytes depending on the character), then each byte is represented as 8 binary digits.

How to Use

Step-by-step guide 3 steps

1 Enter Text: Type or paste the plain text string you wish to convert (e.g., `ABC`).
2 Convert: Click "Encode to Binary".
3 View Binary Code: The output displays the text as a sequence of binary digits (0s and 1s), often separated by spaces for each 8-bit byte.

FAQ

Common questions 3 questions

What standard is used for the conversion?

The conversion typically uses the ASCII (American Standard Code for Information Interchange) standard to map each character to an 8-bit binary value.

What is the binary format displayed?

Each character is usually represented by a group of 8 binary digits (a byte), which is the standard way to encode a single text character.

Is binary encoding secure?

No, binary is a data representation format, not an encryption method. The conversion is reversible and should not be used for security purposes.
