Create ZigZag Text

Zigzag text is a visual ASCII art pattern where characters arrange in a wave-like formation across multiple lines. This tool uses the Rail Fence Cipher algorithm—characters are placed diagonally down then up across imaginary 'rails' (rows). For example, 'HELLO WORLD' with 3 rows becomes a pattern where letters appear to wave up and down. You can adjust the wave height (2-8 rows) to control amplitude. The result is perfect for ASCII art, visual effects in code comments, or understanding cipher concepts visually.

The Rail Fence Cipher is a classic transposition cipher where text is written in a zigzag pattern across multiple 'rails' (rows). Characters go diagonally down to the bottom rail, then diagonally up to the top, repeating this pattern. Our tool visualizes this cipher by placing characters in their exact positions with spaces filling empty spots, creating the iconic wave pattern. The encrypted version would read each rail left-to-right. It's both a cryptographic concept and artistic visualization. Height controls how many rails exist (2-8), affecting the wave's amplitude.

Yes! Enable Batch Mode to process multiple texts simultaneously. Enter each text on a separate line and the tool will create individual zigzag patterns for each, separated by blank lines in the output. Perfect for: generating ASCII art headers for multiple files, creating wave patterns for lists of usernames, processing datasets for visual formatting, or batch-generating cipher visualizations for educational materials. Statistics panel shows total output lines and characters added across all batch items.

Use the Wave Height slider (2-8 rows) to control the zigzag amplitude. 2 rows: Minimal wave, characters alternate between two lines—subtle effect. 3-4 rows: Medium wave—classic Rail Fence Cipher visualization. 5-6 rows: Tall wave—dramatic visual effect. 7-8 rows: Maximum amplitude—extreme ASCII art patterns. Higher values create more spacing and vertical spread. The statistics panel displays your current height setting. Experiment with different heights to find the perfect visual balance for your use case.

Zigzag patterns rely on character alignment—every character must occupy the same horizontal width. Monospace fonts (like Courier, Consolas, Monaco) give each character identical width, preserving the wave pattern. Proportional fonts (Arial, Times New Roman) have variable widths (i is narrower than m), breaking alignment and making the pattern look misaligned. Use zigzag text in: code editors (VS Code, Sublime), terminals (bash, PowerShell), monospace text areas (Discord/Reddit code blocks), or documentation with monospace CSS. Our preview uses a dark terminal theme for authenticity.

Absolutely! Click the Upload button to load .txt or .md files. The tool processes files 100% in your browser—no server uploads, complete privacy. After creating zigzag patterns, click Save to download the output as a .txt file. Perfect for: batch processing text files for ASCII art, creating cipher visualization datasets, transforming entire documents into wave patterns, or generating headers for multiple code files. Combined with batch mode, you can process multi-line files where each line becomes its own zigzag pattern.

Click Show Comparison to display the original text and zigzag pattern side-by-side. The original appears in a blue panel, the zigzag in a dark terminal-style panel with green text. This helps you: (1) Verify the transformation worked correctly, (2) Understand how the Rail Fence algorithm places characters, (3) Compare input vs output for educational demonstrations, (4) Debug or fine-tune your patterns before using them. Essential for teaching cipher concepts, explaining pattern generation, or quality-checking batch outputs before downloading.

The statistics panel displays four key metrics: (1) Input (blue): Original text character count, (2) Output (green): Total characters in zigzag pattern (includes spaces), (3) Lines (purple): Number of lines in the output pattern, and (4) Height (orange): Current wave height (rows) setting. These metrics help you understand: text expansion (output is always larger due to spacing), vertical space usage (lines created), pattern complexity, and current amplitude. Useful for fitting patterns into specific spaces or understanding storage requirements.

Completely safe. All processing happens 100% client-side in your browser using JavaScript. Your text never leaves your device, isn't sent to servers, isn't logged or stored. Even uploaded files are processed locally in browser memory. You can verify by checking your browser's Network tab—no data transmission occurs. This is a privacy-first tool perfect for creating zigzag patterns from confidential documents, proprietary code, personal messages, or any sensitive data. Use with confidence for any text, no matter how private.
