How do I convert uppercase text to lowercase?

Paste your UPPERCASE text into the input field and select 'lowercase' from the case type dropdown. The converted text appears instantly. Click 'Copy' to copy it to your clipboard.

What is the difference between Title Case and Capitalized Case?

Title Case follows English grammar rules — it capitalizes major words but keeps minor words like 'a', 'an', 'the', 'and', 'or', 'in', 'of' lowercase (e.g., 'The Lord of the Rings'). Capitalized Case capitalizes every word regardless (e.g., 'The Lord Of The Rings').

What is camelCase and when is it used?

camelCase joins words together with each word after the first capitalized and no spaces or separators (e.g., 'getUserName'). It's the standard naming convention for variables and functions in JavaScript, TypeScript, and Java.

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., 'MyComponent'). PascalCase is commonly used for class names in most languages and for React component names.

When should I use snake_case vs kebab-case?

snake_case (words_separated_by_underscores) is standard in Python, Ruby, and SQL databases. kebab-case (words-separated-by-hyphens) is standard for CSS class names, URL slugs, and CLI arguments. The choice depends on your language or framework conventions.

Is my text stored or sent to a server?

No. All text conversion happens entirely in your browser using JavaScript. Your text never leaves your device and is not stored, logged, or transmitted to any server.

Can I convert text from a PDF that is all capitals?

Yes. Copy the ALL CAPS text from your PDF, paste it into the converter, and select 'Sentence case' or 'Title Case' to convert it to readable text. Sentence case is usually the best choice for body text.

Developer Naming Conventions

7 programming case types with language-specific usage

Each programming language has preferred naming conventions. Using the wrong case can break linters, violate style guides, or cause bugs in case-sensitive systems.

Case	Used In	Example
camelCase	JavaScript / TypeScript variables, Java methods	`getUserName`
PascalCase	React components, C# classes, Go exported types	`UserProfile`
snake_case	Python variables, Ruby, SQL columns, Rust	`user_name`
kebab-case	CSS classes, URL slugs, CLI flags, HTML attributes	`font-size`
CONSTANT_CASE	Environment variables, constants, enum values	`MAX_RETRIES`
dot.case	Java packages, config keys, file extensions	`app.config.name`
path/case	File paths, URL routes, module imports	`src/utils/format`

Title Case vs Capitalized Case

Understanding AP/APA capitalization rules for headings

Title Case follows English grammar rules — it capitalizes major words but keeps minor words lowercase. This tool applies AP/APA style conventions:

Capitalize

Nouns, verbs, adjectives, adverbs, pronouns, first & last word

Keep Lowercase

Articles (a, an, the), conjunctions (and, but, or), prepositions (at, by, for, in, of, on, to)

Title Case: The Lord of the Rings

Capitalized: The Lord Of The Rings
