When to use each case style
UPPERCASE works for short labels, warnings, and acronyms, but whole sentences in caps read as shouting — use sparingly. lowercase is handy for normalizing data like email addresses or hashtags before comparing them. Title Case capitalizes every word and is the standard for headlines, book titles, and headings. Sentence case capitalizes only the first word of each sentence, which is the cleanest choice for body text and increasingly popular for modern web headings. One tip: title case converters capitalize every word mechanically, so double-check small words (a, the, of) against your style guide for formal publishing — but for everyday use, the result is exactly right.
Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case Capitalizes Every Word, which suits headlines. Sentence case capitalizes only the first word of each sentence, which suits body text and modern minimal headings.

No. Conversion happens entirely in your browser. Your text never leaves your device.
Can I convert a whole document at once?

Mostly. The converter applies standard rules mechanically, so unusual capitalizations inside words may need a quick manual touch-up afterward.
