Case Converter - Uppercase, Lowercase & Title Case Tool
Did you accidentally leave Caps Lock on and type a whole paragraph? Don't delete it! Our Case Converter Tool is a simple yet powerful utility that allows you to transform text casing instantly. Whether you need to capitalize titles for a blog post or lowercase email addresses, we've got you covered with five different conversion modes.
Available Conversion Modes
- UPPERCASE: Converts all letters to capitals. Useful for headers, emphasizing warnings, or creating attention-grabbing headlines. Example: "hello world" → "HELLO WORLD"
- lowercase: Converts everything to small letters. Perfect for data cleaning, email addresses, usernames, or when you need consistent formatting. Example: "HELLO WORLD" → "hello world"
- Title Case: Capitalizes the first letter of every word. Standard for headlines, book titles, movie names, and proper nouns. Example: "hello world today" → "Hello World Today"
- Sentence case: Capitalizes only the first letter of the first word and after periods. Best for correcting accidental lowercase typing or formatting regular sentences. Example: "hello world. this is great." → "Hello world. This is great."
- Alternating Case: Alternates between lowercase and uppercase letters. Commonly used for internet memes, creative styling, or sarcastic text. Example: "hello world" → "hElLo wOrLd"
