Understanding the Different Case Options
Sentence Case
The Sentence case converter transforms any text into a structured paragraph. It works by capitalizing the very first letter of every sentence, converting the rest of the text into lowercase, and capitalizing standalone "i"s into "I"s. Every letter following a full stop or punctuation mark is automatically capitalized.
Lower Case
If you are wondering how to uncapitalize text, the lower case converter turns all characters into small letters. It is ideal for cleaning up copy or fixing text typed in all CAPS.
UPPER CASE
The UPPER CASE transformer makes every letter into a CAPITAL letter while preserving spacing and numbers. Use this format when you need bold emphasis, legal notices, or header tags.
Capitalized Case
The Capitalized Case converter automatically converts the starting letter of every single word into uppercase while keeping all other letters lowercase.
Title Case
The Title Case converter ensures proper capitalization for article headlines, book titles, and essays by capitalizing major words while keeping minor conjunctions lowercase.
aLtErNaTiNg cAsE
The alternating case tool transforms text into a pattern that alternates between lowercase and uppercase letters for fun, meme-style formatting.
