How to Use Kebab Case Converter — Step by Step
Step 1: Enter your text
Type or paste any text into the input box. This can be words separated by spaces, underscores, camelCase, or any other format. The tool normalizes all input before converting to kebab-case.
Step 2: Watch the conversion happen
The tool converts your text in real time as you type. All words are lowercased and joined with hyphens. Special characters are stripped and every word boundary is detected automatically.
Step 3: Review and adjust if needed
Check the output for any unexpected results. Numbers are treated as word boundaries. If the result isn't quite right, adjust your input and watch it update instantly.
Step 4: Copy the result
Click the Copy button to grab the kebab-case result and paste it directly into your URL, CSS file, or package.json. The conversion is instant and requires no page reloads.
Real-World Examples
URL Slug: You are creating a blog post URL. Type "How to Bake Bread at Home" and the tool outputs "how-to-bake-bread-at-home" — a clean, SEO-friendly slug that search engines love.
CSS Class Name: Your design system uses kebab-case for class names. You type "primary button background" and get "primary-button-background" — ready to use in your stylesheet.
npm Package: You are naming a new npm package. Type "my awesome utility" and get "my-awesome-utility" — a valid, publishable package name.
HTML ID Attribute: You need unique IDs for form elements. Type "user email address field" and get "user-email-address-field" — a valid, semantic HTML ID.
File Naming: Your project uses kebab-case for file names. Type "Main Component Header" and get "main-component-header.js" — consistent with your team's naming convention.
GraphQL Field Names: Your GraphQL schema uses kebab-case for field names. Type "user profile image" and get "user-profile-image" — ready for your schema definition.

Tips & Best Practices
- Start with descriptive text: Type full words like "user email address" rather than abbreviations. The converter handles the rest.
- Handle acronyms carefully: "API key" becomes "api-key" (not "a-p-i-key"). For preserving acronyms, consider manual adjustment after conversion.
- Use for URL slugs: Kebab-case is the SEO standard for URLs. Combine with Slug Generator for advanced slug options.
- Combine with other case tools: Use Camel Case for JS variables, Snake Case for Python/DB, kebab-case for URLs/CSS.
- Preserve intentional casing: If you need specific capitalization (like "iPhone" or "APIKey"), convert the base words then manually adjust.
- Batch convert for CMS migration: Paste multiple titles (one per line) to convert many slugs at once for content migrations.
- Use for CSS BEM methodology: Block__Element--Modifier uses kebab-case for elements and modifiers. This tool generates perfect BEM class names.
- Validate against existing slugs: After conversion, check your CMS to ensure the slug doesn't already exist.

Frequently Asked Questions
Q: What is kebab-case format?
A: kebab-case is a naming convention where all words are lowercase and separated by hyphens. For example, "hello world" becomes "hello-world". It is widely used for URL slugs, CSS class names, HTML IDs, and npm package names.
Q: What is the difference between kebab-case and snake_case?
A: kebab-case uses hyphens as separators (hello-world) while snake_case uses underscores (hello_world). kebab-case is preferred for URLs and CSS, while snake_case is common in Python and databases.
Q: Does it handle multiple words and special characters?
A: Yes. The converter handles any number of words, strips special characters, and joins everything with hyphens. "Hello, World! How are you?" becomes "hello-world-how-are-you".
Q: Is my text stored on a server?
A: No. All processing happens locally in your browser. Your text never leaves your device.
Q: Can I use this for URL slug generation?
A: Absolutely. kebab-case is the standard format for SEO-friendly URL slugs. This tool produces clean, lowercase, hyphen-separated text that is perfect for URLs.
Q: Is there a character limit?
A: No. You can convert text of any length instantly. The tool works in your browser with no input restrictions.
Q: What's the difference between kebab-case and PascalCase?
A: kebab-case is all lowercase with hyphens (hello-world). PascalCase capitalizes each word with no separators (HelloWorld). Use Pascal Case Converter for class names and constructor functions.
Q: How does it handle acronyms like API or HTML?
A: Acronyms are treated as single words: "html parser" → "html-parser", "api key" → "api-key". For preserving acronym casing ("HTMLParser"), manually adjust after conversion.
Q: Can I convert multiple lines at once?
A: Yes. Paste multiple lines — each line is converted independently. This is useful for batch-converting article titles to URL slugs.
Q: Does it work with non-English characters?
A: The tool works best with ASCII letters. Non-ASCII characters may be stripped or handled unpredictably. For internationalized slugs, use a dedicated slug generator with Unicode support.
