Case Converter
Convert text between uppercase, lowercase, title case and sentence case.
Accidentally left caps lock on? Pasted text in the wrong case? This case converter fixes it in one click. Just paste your text above and pick the case you need: uppercase, lowercase, title case, sentence case or developer naming formats.
Available Case Options
- UPPERCASE - Every letter becomes a capital. Good for short headings and labels, but hard to read in long blocks.
- lowercase - Every letter becomes small. Useful for cleaning up text that was typed with caps lock on.
- Title Case - Capitalizes the first letter of each word. Standard format for book titles and article headlines.
- Sentence case - Only capitalizes the first letter of each sentence. This is how most everyday writing looks.
- aLtErNaTiNg CaSe - Alternates upper and lowercase letters. Useful for memes, jokes and informal social posts.
- camelCase / PascalCase - Removes spaces and capitalizes word boundaries. Developers use these in languages and frameworks that prefer joined names.
- snake_case / kebab-case - Replaces spaces with underscores or hyphens. Common in Python code, URLs, file names and database fields.
When to Use Each Case
Title case works best for article headlines, book titles and product names. Sentence case feels more natural and is great for blog subheadings. If you're a developer, camelCase and snake_case save time compared to manually reformatting variable names. For long paragraphs, avoid all caps unless the style is intentional. It slows readers down and can feel like shouting.
Common Pitfalls
Basic case converters can mess up proper nouns. For example, converting "I visited Google in India" to lowercase gives "i visited google in india." This tool keeps things simple - it converts everything you give it. If you need smart capitalization that preserves proper nouns, double-check the output before using it.

Frequently Asked Questions
How do I use the Case Converter?
Paste text, choose a case format and copy the result. It is useful for headings, filenames, code names and quick cleanup. Review the output when the text includes names, acronyms or brand terms.
What is the difference between title case and sentence case?
Title case capitalizes major words in a heading. Sentence case capitalizes the first word and proper nouns. Sentence case feels more natural for buttons, help text and many modern interfaces.
Can it make camelCase or snake_case?
Yes. These formats are common in code, URLs and file names. Review the result if your text has symbols, numbers or acronyms because naming rules can vary by project.
Will it keep proper nouns correct?
It applies rules to the whole text. It cannot always know that "iPhone", "NASA" or "McDonald" needs special casing. Scan the result before using it in public copy.
Is this safe for private text?
