How the case converter works
UPPERCASE and lowercase change every letter, including accented letters such as é and ü. Title Case capitalises the first letter of each important word, and Sentence case capitalises only the first letter of each sentence, like ordinary prose.
Title Case follows the common headline style: short words such as a, an, the, and, of and to stay lowercase unless they start or end the line, and both parts of hyphenated words are capitalised. Sentence case also restores the word I. Everything runs in your browser.
The logic
Title Case: lowercase the text, then capitalise the first letter of every word except short articles, conjunctions and prepositions in the middle of a line.
Sentence case: lowercase the text, then capitalise the first letter at the start and after each full stop, question mark, exclamation mark or line break.
Example
In Title Case, "a guide to the best walks in the lake district" becomes "A Guide to the Best Walks in the Lake District".
In Sentence case, "THIS IS URGENT. PLEASE REPLY TODAY!" becomes "This is urgent. Please reply today!"
Tips and common mistakes
Fix accidental Caps Lock
Typed a paragraph in capitals by mistake? Choose Sentence case to fix it in one go, then check names and places.
Proper nouns need a check
Lowercase and Sentence case can't know that London or Maria are names. Capitalise them again after converting.
House styles differ
Style guides disagree on which small words to capitalise in titles. Adjust a word or two if your publication has its own rules.
Check the length afterwards
Use the word counter to check the converted text still fits your limit.

Frequently asked questions
Does it change punctuation or spacing?
No. Only letters change; spaces, punctuation and line breaks stay exactly as they are.
Does it work with other languages?
Accented letters and alphabets such as Greek and Cyrillic convert correctly. The Title Case rules for small words are based on English.
Is my text stored?
No. Conversion happens in your browser and nothing is uploaded or saved.
Can I get my original text back?
Keep a copy if you might need the original. You can always convert again to whichever case you want.
