Encoder/Decoder

A comprehensive utility for encoding and decoding text across multiple formats, including standard web encodings and classic cryptographic ciphers.

🚀 Why Use Encoder/Decoder?

The Encoder/Decoder tool is a versatile utility designed for developers, security researchers, and anyone needing to transform text data. It provides a unified interface for common encoding tasks and simple encryption methods, all processed locally in your browser for maximum privacy.

Key Benefits

  • Multi-Format Support: Handle everything from Base64 to Morse code in one place.
  • Real-Time Results: See transformations instantly as you type.
  • Privacy-First: All processing happens client-side; your data never leaves your device.
  • History Tracking: Quickly access your last 10 operations, saved locally for convenience.

🛠️ Key Features

Supported Formats

  • Base64: Standard binary-to-text encoding for data transfer.
  • URL: Safe encoding for URI components.
  • HTML Entities: Convert special characters to HTML-safe entities (includes a reference table).
  • Hexadecimal: Transform text into its hex representation.
  • Binary: Convert text to 8-bit binary sequences.
  • ASCII Codes: View text as decimal ASCII values.
  • Morse Code: Standard international Morse code translation.
  • ROT13: A simple substitution cipher that replaces a letter with the 13th letter after it in the alphabet.
  • Atbash Cipher: A substitution cipher formed by reversing the alphabet.
  • Caesar Cipher: A shift cipher with a configurable shift value (key).
  • XOR Cipher: Bitwise XOR encryption using a custom secret key (input/output handled as Hex).

Advanced Functionality

  • Configurable Parameters: Adjust Caesar shift values or set custom XOR keys.
  • Smart History: Automatically saves recent operations with input/output previews.
  • One-Click Utilities: Easily copy results, clear inputs, or swap output back to input for multi-stage encoding.
  • Reference Tools: Built-in HTML entity reference table for quick lookups.

📖 How to Use

  1. Select Encoding Type: Choose your desired format from the grid of available options.
  2. Choose Mode: Toggle between Encode and Decode modes.
  3. Input Text: Type or paste your text into the input area. The tool processes data in real-time.
  4. Configure (Optional): For Caesar or XOR ciphers, enter the required shift value or secret key.
  5. Manage Results:
    • Use Copy to grab the output.
    • Use Use as Input to perform further operations on the result.
    • Review Recent Operations to revisit previous work.
