Frequently asked questions

What case options does this tool support?

UPPERCASE, lowercase, Title Case, Sentence case, and aLtErNaTiNg cAsE. Pick any button and the result updates instantly.

Does the sentence case option handle abbreviations correctly?

Not always — since it splits sentences on ., !, and ?, abbreviations like "Mr." or "U.S." followed by a capital letter can be treated as a new sentence. Review the result for text with lots of abbreviations.

Does title case follow style-guide rules that skip small words?

No — it capitalizes every word for simplicity. If you need AP or Chicago-style rules that skip short words like "a" or "the", adjust those manually afterward.

Is my text sent to a server?

No. Every conversion runs entirely in your browser — nothing is transmitted or logged.
