Typography & Data Formatting

Did you know? Writing in ALL CAPS is widely considered "shouting" online. Studies show it reduces reading speed by 10-20% because the letters lack distinctive shapes compared to lowercase text.

When to use different cases?

  • Sentence case

    The standard for body text, essays, and articles. It is the easiest to read and feels neutral and professional.

  • Title Case

    Used for headlines, book titles, and email subjects. It conveys authority and importance.

  • lowercase

    Essential for programmers and data analysts. Email addresses, usernames, and database entries are often normalized to lowercase to prevent duplicates.

  • UPPERCASE

    Use sparingly for acronyms (NASA, FBI), warnings, or extreme emphasis.

The Importance of Clean Text

Copying text from PDFs or websites often introduces "invisible" formatting issues—double spaces, non-breaking spaces, or weird line breaks. This can break code or make documents look unprofessional. Our tool's Clean Text feature strips away these hidden characters, leaving you with pure, plain text ready for any use.

Frequently Asked Questions

Does this tool store my text?
No. This tool runs entirely in your browser using JavaScript. Your text never leaves your device and is never sent to any server. It is 100% private and secure.
What is the difference between Title Case and Capitalized Case?
Capitalized Case capitalizes the first letter of EVERY word (e.g., 'The Boy Who Lived'). Title Case is smarter; it capitalizes major words but leaves minor words like 'and', 'the', 'of' in lowercase (e.g., 'The Boy who Lived').
What is Sentence case?
Sentence case capitalizes only the first letter of the first word in a sentence and proper nouns. It is the standard format for most written content, emails, and articles.
Can I convert text from a PDF?
Yes. Copying text from PDFs often results in weird line breaks and extra spaces. Paste it here, use the 'Sentence Case' and 'Clean Spaces' features to fix the formatting instantly.
Why is 'Inverse Case' useful?
Inverse Case (swapping lower to upper and vice versa) is often used to fix text that was accidentally typed with CAPS LOCK on. It creates a fun, playful text style as well.
