Hierarchical Tree Structure

Build complex hierarchical trees with unlimited depth. Add, remove, and organize clades and organisms using intuitive controls. Label each node with scientific or common names to create detailed phylogenetic relationships.

Customizable Appearance

Adjust line thickness and font size. Choose from preset colors or use a custom color picker. Create professional diagrams that match your style.

Automatic Layout

The cladogram automatically arranges branches in a clean, readable layout. Equal spacing and proper alignment ensure clarity at any size.

High-Quality Export

Download your cladogram as a high-resolution PNG image. Perfect for presentations, papers, posters, and educational materials. No watermarks.

Educational Tool

Perfect for biology students, teachers, and researchers. Visualize evolutionary relationships, teach phylogenetic concepts, and create study materials.

How It Works

Step 1: Build Your Tree

Start with the default tree structure and customize it. Click the "+" button on any node to add child branches. Enter names for organisms or taxonomic groups. Create nested hierarchies to represent your evolutionary relationships.

Step 2: Customize Appearance

Adjust line thickness and font size using the sliders. Choose a color scheme that works for your presentation or publication. Toggle node visibility with zoom controls.

Step 3: Review the Diagram

The cladogram updates automatically as you make changes. Preview your phylogenetic tree in real-time to ensure it looks exactly right.

Step 4: Download

Export your finished cladogram as a high-resolution PNG image. Use it in presentations, papers, educational materials, or anywhere you need to show evolutionary relationships.

FAQ

What is a cladogram?

A cladogram is a diagram showing evolutionary relationships between organisms. It displays how species or groups share common ancestors through branching patterns.

How do I use the Cladogram Maker?

Click "Start Creating" to open the editor. Use the tree structure panel to add organisms by clicking "+" buttons. Customize the appearance with line thickness, font size, and color options, then download your finished diagram.

Can I add more than 5 organisms?

Yes! Add as many organisms as you need. The cladogram automatically adjusts the layout to accommodate any number of branches.

What format does it export?

Cladograms are exported as high-resolution PNG images. This format works in presentations, documents, websites, and print materials.

Is this tool free?

Completely free with no hidden costs, watermarks, or signup required. Create unlimited cladograms for any purpose.

Does it work offline?

Yes, once the page loads, you can work offline. All processing happens in your browser—no internet connection needed after initial load.

Can I use this for educational purposes?

Absolutely! Perfect for biology classes, textbooks, presentations, study guides, and research papers. Use it freely for teaching and learning.

What's the difference between a cladogram and phylogenetic tree?

Cladograms show branching relationships without indicating time or degree of change. Phylogenetic trees may include branch lengths representing evolutionary distance or time.

Can I customize the colors?

Yes! Choose from preset colors or use the custom color picker for any color you need. Match your branding, publication style, or presentation theme.

Does it save my work automatically?

Currently, work is not automatically saved. We recommend downloading your cladogram when finished. Future updates may include save functionality.
