Text Case Converter

Convert text between uppercase, lowercase, title case, camelCase, and more instantly — free and accurate.

Overview

What is a text case converter?

A text case converter rewrites any text into a different capitalization style — uppercase, lowercase, title case, sentence case, or one of the programming naming conventions like camelCase, PascalCase, snake_case, or kebab-case.

It's useful for far more than tidying up writing — fixing inconsistent headline capitalization, converting a phrase into a valid variable name, or generating a URL-friendly slug all rely on the same underlying case conversion logic.

Tips

Best practices to keep in mind

A few things worth knowing about picking the right case style.

Title case rules vary between style guides — some capitalize every word, others keep short words like "a" and "the" lowercase. This tool capitalizes every word, so double-check against your specific style guide for headlines.
camelCase and PascalCase are the standard naming conventions for variables and class names in most programming languages — use camelCase for variables and functions, PascalCase for classes and components.
snake_case is common in Python and database column names, while kebab-case is the standard for URL slugs and CSS class names — picking the right one for your context avoids inconsistent codebases.
Converting case doesn't fix spelling or grammar — run a quick proofread after converting, especially with sentence case, since it only capitalizes the first letter of each sentence, not every proper noun.

FAQs

Frequently asked questions

Have questions about converting text case? Here are the most common ones our users ask before getting started.

Is this text case converter free to use?

Yes, the text case converter is completely free with no signup, no usage limits, and no hidden charges. It runs entirely in your browser using JavaScript, so no text is sent anywhere and no account is required to convert between case styles.

What case styles does this tool support?

This converter handles UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case — covering both everyday writing styles and the naming conventions used across most programming languages and URL formats.

What's the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter and capitalizes the first letter of each subsequent word, such as firstName, and is the standard for variables and functions in most languages. PascalCase capitalizes every word including the first, such as FirstName, and is the standard for class names and React components.

Why would I need snake_case or kebab-case?

snake_case, which separates words with underscores, is the common convention for database column names and Python variables. kebab-case, which separates words with hyphens, is the standard for URL slugs and CSS class names. Using the right convention for the right context keeps a codebase or URL structure consistent and easy to scan.

Does this tool store or share the text I convert?

No. The entire conversion happens locally in your browser — the text you enter is never transmitted to a server, logged, or stored anywhere. You can convert as much text as you need without any of that content being retained.
