About the Case Converter
This tool changes the capitalisation of your text between four styles: all uppercase, all lowercase, title case, and sentence case. Paste any text and switch its case with one click, without retyping a word.
The four cases explained
Uppercase makes every letter a capital, useful for headings, acronyms, or emphasis. Lowercase makes everything small, handy for normalising text or for a deliberately casual style. Title case capitalises the first letter of each word, the convention for headlines, titles, and proper names. Sentence case capitalises only the first letter of each sentence, which is how ordinary prose is written. Each suits a different context, and switching between them by hand is tedious and error-prone, which is what this tool removes.
Why consistent case matters
Inconsistent capitalisation looks unprofessional and can confuse readers. Content style guides usually specify a case convention for headings and titles, and matching it keeps writing polished. Beyond appearance, consistent case matters for data: a list of names or categories with mixed capitalisation can cause duplicates and sorting problems in spreadsheets and databases, so normalising case is a common data-cleaning step.
How it handles your text
Uppercase and lowercase are straightforward transformations of every letter. Title case capitalises the first letter following any space, so each word begins with a capital. Sentence case capitalises the first letter of the text and the first letter after each sentence-ending punctuation mark. The tool changes only capitalisation; your words, spacing, and punctuation are otherwise preserved exactly.
Common uses
Writers use it to fix headings that were typed in the wrong case or to convert text pasted from an all-caps source. Data workers use lowercase or consistent casing to clean lists before importing them. Anyone who has accidentally typed a long passage with caps lock on knows the value of fixing it in one click rather than retyping. It is also useful for quickly reformatting titles to match a required style.

Frequently Asked Questions
How do I change text to uppercase or lowercase?
Paste your text and choose UPPERCASE or lowercase — every character switches instantly, so you never have to retype. Switch to another case any time to change it again.
How do I convert text to Title Case?
Choose Title Case and it capitalises the first letter of each major word — ideal for headlines and titles. For example “the quick brown fox” becomes “The Quick Brown Fox”.
What is Sentence case?
Sentence case capitalises only the first letter of each sentence (and “I”), leaving the rest lowercase — the normal way you write prose, and handy after pasting text that was in ALL CAPS.
What case options are available?
UPPERCASE, lowercase, Title Case and Sentence case — covering titles, headings, form fields and social posts, without retyping a single word.
Is the case converter free and private?
Yes — it is free, needs no sign-up, and works entirely in your browser, so your text is never uploaded or stored.
