Encode Text with Our Caesar Cipher Encoder

Caesar Cipher Encoder lets you quickly convert plain text into cipher text using any shift value you choose — perfect for secret messages, classroom demonstrations, or simple text obfuscation.

We have created this amazing Caesar Cipher Encoder tool which can transform plain text into encoded cipher text using various shift values. It's perfect for creating secret messages, educational purposes, and simple text obfuscation.

Enter the Plain Text and Select the shift value and see the encoded results.

How to use Caesar Cipher Encoder?

  • Open the Caesar Cipher Encoder.
  • Paste or upload your plain text.
  • Select a shift value (1–25)
  • Click Encode (or let Auto mode do it instantly)
  • Copy or download your encoded text.

List of Encoder Features

  • Manual shift selection (1-25)
  • Keeps letter case and punctuation intact
  • Encode numbers (0→1, 1→2, ... 9→0)
  • Built-in ROT13 support
  • Real-time encoding while you type
  • Clean, streamlined interface for quick use
  • Enhanced number encoding options
  • Card-based shift selection

Example

Plain text: THIS IS A TEST

Encoded with shift 3: WKLV LV D WHVW

Dedicated Encoding

Focused solely on encoding text with a streamlined interface. Single "Encode Text" button for quick and efficient text obfuscation.

Flexible Shift Options

Choose from 25 different shift values or enter a custom value. Special support for ROT13 (shift 13) which is self-reversible.

Preserve Formatting

Keep original letter case (uppercase/lowercase) and preserve spaces, numbers, and special characters unchanged during encoding.

Number Encoding

Enhanced feature to encode numbers along with letters. When enabled, numbers are shifted by the same amount (0→1, 1→2, ... 9→0).

Automated Encoding

This feature provides instant feedback which makes it quicker to get results and test different shift values. It's on by default.

Card-Based Interface

Easy selection of common shift values with visual feedback. Each card shows the shift pattern and description for better understanding.
