About text case conversion
Text case refers to the capitalization pattern applied to letters in a string. Different contexts call for different cases — headings, database fields, code identifiers, and social posts all follow different conventions.
This tool converts any text between the three most common cases instantly, without any typing or reformatting by hand.
When to use each case
- UPPERCASE — Acronyms, emphasis, call-to-action buttons, labels, SQL keywords
- Title Case — Article and blog headings, book titles, product names, email subjects
- lowercase — Usernames, slugs, hashtags, code variable normalization
Frequently Asked Questions
What is Title Case?
Title Case capitalizes the first letter of every word and lowercases the rest. For example, "the quick brown fox" becomes "The Quick Brown Fox". It is commonly used for article headings, book titles, and product names.
What is the difference between UPPERCASE and Title Case?
UPPERCASE converts every character to its capital form — "hello world" becomes "HELLO WORLD". Title Case only capitalizes the first letter of each word — "hello world" becomes "Hello World". UPPERCASE is used for emphasis, acronyms, and labels; Title Case is used for headings and titles.
