FAQ

When should I use Title Case vs Sentence case?

Title Case capitalizes every major word — use it for article titles, blog headlines, and book names. Sentence case capitalizes only the first word — use it for body text, email content, and casual writing.

Does Title Case handle small words correctly?

Yes. The tool intelligently handles articles (a, an, the), conjunctions (and, but, or), and prepositions (in, on, at) — keeping them lowercase unless they’re the first or last word in the title.

Can I use this for bulk text conversion?

The tool handles any amount of pasted text. For very large documents, paste in sections to verify the conversion is correct.

What does tOGGLE cASE do?

Toggle case inverts the case of every letter — uppercase becomes lowercase and vice versa. It’s useful for quickly fixing text typed with the Shift key held at the wrong moments.

Tips

• For SEO title tags, Title Case often performs better visually in search snippets
• Use Sentence case for meta descriptions — Google typically displays them in sentence case anyway
• The copy button saves time when converting multiple pieces of text in sequence
