Bytes to String Converter

Conversion Guide

  1. Input Your Bytes
    • Enter bytes in any supported format (auto-detected by default)
    • Formats: Hex (2 chars), Binary (8 bits), Decimal (0-255), Octal (3 digits)
    • Separators: Spaces, commas, or any non-alphanumeric characters
  2. Configuration
    • Auto-detect: Automatically determines input format
    • Strict mode: Validates input according to selected format
    • Show byte array: Displays intermediate byte values
  3. Special Cases
    • Base64: Decodes entire input as Base64 string
    • UTF-8: Properly handles multi-byte sequences
    • Invalid bytes: Shows replacement character (�) when decoding fails

Technical Details

Decoding Process

Conversion workflow:

  1. Input normalization (remove non-format characters)
  2. Format detection or manual selection
  3. Conversion to byte array (Uint8Array)
  4. UTF-8 decoding using TextDecoder
  5. Error handling for invalid sequences

Format Detection Rules

Auto-detection priority:

  • Base64: If input matches Base64 regex
  • Binary: If only 0s and 1s (length multiple of 8)
  • Hexadecimal: If only 0-9, a-f, A-F (even length)
  • Octal: If only 0-7 (length multiple of 3)
  • Decimal: Numbers 0-255 separated by non-digits
