Overview
This is a straightforward tool that allows you to adjust the letter casing of text, enabling transformations between uppercase, lowercase, title case, sentence case, and capitalized formats.
Case Styles
There are seven case styles available:
-
Uppercase - This style consists of capital letters only and is often used in headings and special situations where text emphasis is necessary.
-
Lowercase - This style uses only lowercase letters.
-
Each Word - In this style, the first letter of each word is capitalized. It is often used in blog post titles (see Title Case).
-
Title Case - A variation of the "Each Word" case style where the first letter of each word is capitalized, except for certain short words.
-
AP Title Case - Similar to Title Case, this style capitalizes each word, with exceptions for articles, prepositions, or conjunctions with fewer than 4 letters.
-
Sentence Case - This style capitalizes the first word of each sentence.
-
Shuffle - A mixed-case style where the letter casing is randomized. This is often used for stylistic purposes.
Examples
Uppercase
THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.
Lowercase
the quick brown fox jumps over the lazy dog.
Each Word
The Quick Brown Fox Jumps Over The Lazy Dog.
Title Case
The Quick Brown Fox Jumps over the Lazy Dog.
AP Title Case
The Quick Brown Fox Jumps Over the Lazy Dog.
Sentence Case
The quick brown fox jumps over the lazy dog.
Shuffle
tHE QuicK bRown foX Jumps oVeR The lazy dOG.
Change text case for headings, labels, and copied passages. Compare uppercase, lowercase, word capitals, and title styles in one tool.
How to use
Paste the passage, choose a case style, and apply it. Review names and acronyms after any automatic conversion.
Example
Convert “annual report” to ANNUAL REPORT for an uppercase label, or use Each Word to get Annual Report.
FAQ
Does title case follow every language's rules?
No. The title options use English style heuristics. Review proper names, abbreviations, and publication rules yourself.
A practical task
Use lowercase only when case carries no necessary identity. A model code, acronym, or product name can lose its accepted form during broad conversion. Keep a list of exceptions and restore those names after applying the selected style.
Another useful question
Are Title Case and AP separate full style checkers?
Treat them as capitalization options, not complete editorial proofreaders. The current implementation uses limited English rules and needs a human check for names and house style.
Details for interpreting the result
| Detail | Explanation |
|---|---|
| Case sensitivity | Case sensitive matching distinguishes capital and lowercase letters. Ignoring case merges some of those distinctions, but it does not turn different spellings or word forms into the same term. |
