Convert text formats: UPPERCASE, lowercase, Title Case, Sentence Case, or slugify.
Need to fix caps lock errors, draft blog headings, or convert page titles into clean URL slugs? Retyping text blocks manually wastes time. Our Free online Text Case Converter converts your copy between seven case formats instantly in your browser.
When drafting copy for blogs, books, websites, or software scripts, different case systems serve specific purposes. Standard text formatting includes:
Before launching a website, combine URL slugs with tracking parameters generated in our UTM Campaign Builder. If you want to check word lengths, character statistics, and reading speed diagnostics, try our Word & Sentence Counter.
Developers use space-less case formats to write readable variable names, classes, and file paths:
const toolDetails = {}).export class TextCaseConverter {}).with, of, to) in headings. Title case rules require keeping these in lowercase./café-shop). Always strip accents for clean browser path compatibility.To learn about title formatting rules, check out the APA Title Case Guidelines and review JavaScript string standards at the MDN String toUpperCase Guide.
A text case converter is a formatting utility that automates the process of changing the capitalization style of blocks of text. Instead of manually retyping paragraphs to correct formatting issues, you can paste your text and convert it instantly between styles like UPPERCASE, lowercase, Title Case (capitalizing major words), Sentence Case (capitalizing only the first letter of sentences), camelCase, PascalCase, and URL-friendly slugs.
Title Case format capitalizes the first letter of every major word in a string. Under standard English grammar rules (such as APA or Chicago Manual of Style guidelines), minor words—such as articles (a, an, the), coordinating conjunctions (and, but, for), and short prepositions (in, on, at, to)—are kept in lowercase unless they are the first or last word of the title.
A URL slug is a clean, readable text string used at the end of a web page address to describe its content. Slugs contain only lowercase letters, numbers, and hyphens (e.g. `text-case-converter`). They replace spaces with dashes and strip special symbols, which makes them SEO-friendly and prevents web servers from returning 404 errors.
Both are programming case styles that remove spaces between words to create single string tokens. In camelCase, the first word starts with a lowercase letter, and all subsequent words start with uppercase (e.g. `myVariableName`). In PascalCase, every single word starts with an uppercase letter, including the first word (e.g. `MyClassName`).
Sentence Case relies on standard punctuation marks (like periods, question marks, and exclamation points) followed by spaces to detect sentence boundaries. If you forget to put a space after a period, or if your text block contains unusual punctuation (like abbreviations or decimals), the converter might not recognize the start of a new sentence.
Yes, our case converter handles standard UTF-8 characters and accented European letters (like `é`, `ü`, `ñ`) correctly. However, very unique mathematical symbols, emojis, and specific non-latin alphabets do not have capital or lowercase variants, so their glyph layout remains unchanged during conversions.
Yes, our case converter is completely secure. The conversions are processed locally on your device using client-side JavaScript string APIs (like `.toUpperCase()` and regex replacement functions). We never upload or save your text drafts to any server, keeping your work private.
