Whether you are writing article headlines, naming variables in code, formatting CSS classes, or cleaning up text pasted from an inconsistent source, getting the case right matters. Different contexts call for different conventions — and converting manually is slow, error-prone, and tedious. A text case converter does it in one click.
All letters are capitalised: THIS IS AN EXAMPLE SENTENCE.
When to use it: acronyms (NASA, PDF, API), constants in programming languages (MAX_RETRIES, API_KEY), headings that need visual emphasis, and legal documents that require section titles in all-caps.
When to avoid it: body text — all-caps is significantly harder to read than mixed case, because we recognise words by their shape as well as their letters. A paragraph in all-caps is perceived as shouting.
All letters are small: this is an example sentence.
When to use it: email addresses and usernames, HTML attributes and tag names, hashtags on social media, and code strings that need to be case-insensitive. URLs are conventionally lowercase — a capital letter in a URL doesn't break anything but looks unprofessional.
The first letter of every word is capitalised: This Is an Example Sentence.
When to use it: article titles, blog post headings, book and film titles, product names, and navigation menu items. Title case signals importance and is the standard for English publication headings.
Note on stop words: strict title case rules (AP, Chicago, APA) leave short words like "a", "an", "the", "and", "or" in lowercase unless they are the first word. Simple converters capitalise all words; Criply's tool capitalises all words for simplicity, which is acceptable for most non-publishing uses.
Only the first letter of each sentence is capitalised: This is an example sentence. And this is another one.
When to use it: body text, descriptions, social media captions, email body text, and any context where normal prose conventions apply. Sentence case is the most readable format for extended text.
The first word is lowercase and each subsequent word starts with a capital, with no spaces: thisIsAnExampleSentence
When to use it: variable and function names in JavaScript, TypeScript, Java, Swift, and most C-derived languages — getUserData(), totalPrice, isLoggedIn. Also used in JSON keys in many APIs.
All letters are lowercase and words are separated by hyphens: this-is-an-example-sentence
When to use it: URL slugs (criply.co/pdf/compress), CSS class names (.nav-link, .btn-primary), HTML data attributes (data-user-id), file names (getting-started.md), and package names in npm. Widely used in web development wherever spaces are not allowed.
The word and character count updates in real time so you can track length as you edit. You can chain conversions — for example, paste mixed-case text, convert to lowercase, then copy — without clearing between steps.
Cleaning up pasted content: text copied from PDFs, spreadsheets, or legacy systems often comes in ALL CAPS or inconsistent case. Convert to sentence case or title case to normalise it instantly.
Writing code: convert a plain English function description to camelCase for a variable name, or to kebab-case for a CSS class.
SEO and content: apply consistent Title Case to all blog post headings without retyping or manually capitalising each word.
Social media: create stylised UPPERCASE text for emphasis in posts, or normalise text to Sentence case before publishing.
Does the tool work on long documents?
Yes. There is no character limit — paste any amount of text. The conversion runs instantly in your browser regardless of length.
Is my text uploaded anywhere?
No. All conversions use JavaScript's built-in toUpperCase() and toLowerCase() methods. Your text never leaves your browser.
Why does camelCase remove spaces?
camelCase is a programming naming convention where spaces are not allowed. The converter joins words together and capitalises the first letter of each subsequent word, producing a valid identifier you can use directly in code.
