When to use each case
Each case style has a job it is best at. Here is when to reach for which one:
- UPPERCASE - short warnings, labels and emphasis in small doses. Avoid whole paragraphs: long text in capitals reads as shouting and is harder to scan.
- lowercase - normalizing slugs, file names, hashtags and email addresses, where consistency matters more than grammar.
- Title Case - headlines, blog post titles, book and article titles. Give proper names a quick check afterwards, since no automatic converter knows every name.
- Sentence case - everyday writing: emails, essays, descriptions and captions. It is the standard style for running text.
- camelCase - programming: variable names, function names and identifiers in JavaScript, Java and many other languages.
When a case converter helps
It is handy when you typed a paragraph with caps lock on, need a clean headline for a blog post, or want to turn a phrase into a variable name. Students, writers, bloggers and developers all run into these small formatting jobs, and a converter makes them take seconds.
Frequently Asked Questions
How do I change uppercase to lowercase?
Paste your text and press the lowercase button. All capital letters turn into small letters instantly.
What is the difference between title case and sentence case?
Title case capitalizes the first letter of every word, while sentence case capitalizes only the first letter of each sentence. Proper names may need a quick manual fix afterwards.
What is camelCase used for?
camelCase joins words together with no spaces and capitalizes each word after the first. Programmers use it for variable and function names.
Is my text saved anywhere?
No. The conversion runs in your browser and your text is never uploaded.
