How to Convert Text Case: Step-by-Step Guide

Step-by-Step

1. Paste your text into the tool.
2. Choose the case you want to convert to.
3. Copy the result back out.

The Common Case Types

• UPPERCASE: every letter capitalized — HELLO WORLD.
• lowercase: every letter in lowercase — hello world.
• Title Case: major words capitalized, minor words (articles, short prepositions) lowercase — Hello World, A Tale of Two Cities.
• Sentence case: only the first letter of the sentence capitalized, like ordinary prose — Hello world.

Which One to Use When

• Titles and headings often use Title Case, especially in more formal or traditional contexts (though many modern websites and style guides increasingly favor Sentence case for headings instead — check what convention your specific context expects).
• Body text should almost always stay in Sentence case — normal reading text should never be in all caps or title case.
• UPPERCASE is generally reserved for short labels, acronyms, or deliberate emphasis — using it for long stretches of text reads as shouting and hurts readability.

Fixing Text From a Bad Source

Text copied from a PDF, a scanned document, or an old system with inconsistent formatting sometimes arrives in a case that doesn't match your needs — all caps from a legal document, or inconsistent mixed case from a data export. Converting it to a consistent case is often the fastest way to clean it up before using it elsewhere.
