case converter
Convert text between uppercase, lowercase, title case, and more.
A case converter helps you transform text between different capitalization styles for programming, writing, or formatting needs. This tool is essential for developers writing code with naming conventions, content creators formatting titles, writers preparing manuscripts, and anyone who needs to quickly change text case. By using a case converter, you can ensure consistent formatting, meet coding standards, improve readability, and save time on manual text editing. The tool processes text entirely in your browser, providing instant conversions as you type without any data transmission.
What is case converter?
A case converter is a utility that transforms text between different capitalization and formatting styles. It supports multiple case formats: uppercase (all capital letters), lowercase (all small letters), title case (first letter of each word capitalized), sentence case (first letter of sentence capitalized), camelCase (first word lowercase, subsequent words capitalized, no spaces), PascalCase (all words capitalized, no spaces), kebab-case (lowercase with hyphens), and snake_case (lowercase with underscores). Case conversion is essential for programming where naming conventions matter, content creation where formatting consistency is important, and text processing where standardization is required. All conversion happens in real-time as you type.
Common use cases
- Programming: Convert variable names, function names, or constants to match coding style guides (camelCase, snake_case, PascalCase)
- Content creation: Format titles, headings, or article titles to title case or sentence case for consistency
- Data processing: Standardize text data by converting to lowercase or uppercase for database entries or comparisons
- API development: Convert endpoint names to kebab-case or snake_case for RESTful API naming conventions
- Documentation: Format code examples, variable names, or technical terms to match documentation style
- Text formatting: Quickly format large amounts of text for presentations, documents, or web content
Limitations and common mistakes
- Case conversion may not handle special cases perfectly, such as acronyms, proper nouns, or words that should remain in specific case
- Title case conversion capitalizes the first letter of each word, which may not always match style guide requirements for articles, prepositions, or conjunctions
- CamelCase and PascalCase conversions remove all spaces, which may not preserve intended word boundaries in some contexts
- The tool processes text as-is and does not understand context, so manual review may be needed for proper nouns or technical terms
- Very long texts may experience slight processing delays, though the tool handles most practical text lengths efficiently

Frequently Asked Questions
What case formats are supported?
You can convert text to uppercase, lowercase, title case, sentence case, camelCase, PascalCase, kebab-case, and snake_case. Each format serves different purposes for programming, writing, or formatting needs.
Can I convert large text?
Yes, the tool can handle large amounts of text. Very long documents may experience slight processing delays, but the tool will continue to function correctly for most practical text lengths.
Does the conversion happen in real-time?
Yes, the text is converted instantly as you type. All processing happens in your browser, ensuring fast conversion without any server delays.
What is the difference between camelCase and PascalCase?
CamelCase starts with a lowercase letter (e.g., "myVariable"), while PascalCase starts with an uppercase letter (e.g., "MyVariable"). Both remove spaces and capitalize subsequent words.
How does title case work?
Title case capitalizes the first letter of each word. However, it does not follow style guide rules for articles, prepositions, or conjunctions, so manual review may be needed for formal documents.
Is my text stored or sent to a server?
No. All conversion happens entirely in your browser. Your text is never sent to any server, stored anywhere, or transmitted over the network, ensuring complete privacy.
