Text Case Converter
Convert a list between cases, with title case that keeps small words lowercase.
About this tool
Paste a list and convert it: title case, sentence case, upper, lower, or slug style.
Title case is the one worth having a tool for. Capitalising every word is wrong — articles and short prepositions stay lowercase unless they begin or end the line, so it is "The Rise of the Machines", not "The Rise Of The Machines". A spreadsheet formula gets this wrong every time.
Common questions
Which words stay lowercase in title case?
Articles (a, an, the), coordinating conjunctions (and, but, or, nor) and short prepositions (of, in, on, to, for, with). The first and last word are always capitalised regardless.
Does capitalisation affect SEO?
Not in the content itself. It matters in two places: URLs, where a path is case-sensitive on most servers, and titles, where capitals are noticeably wider and truncate sooner in search results.
What is sentence case?
The first letter capitalised and the rest left alone, as a sentence would be. It is increasingly the house style for headings because it reads faster than title case.
Are acronyms preserved?
Yes. A word already in full capitals is left as it is, so "SEO" and "HTTP" survive title and sentence case rather than becoming "Seo" and "Http".
