Change the letter case of any text — uppercase, lowercase, title case, and more.
- Uppercase Converter An uppercase converter changes every letter in your text to a capital letter, leaving numbers, spaces, and punctuation untouched.
- Lowercase Converter A lowercase converter changes every capital letter in your text to its small-letter form, leaving digits and punctuation unchanged.
- Title Case Converter A title case converter capitalises the first letter of every major word in a headline while leaving short words such as "a", "and", "of", and "the" in lowercase.
- Sentence Case Converter A sentence case converter capitalises the first letter of each sentence and lowercases everything else, exactly as normal prose is written.
- Capitalized Case Converter A capitalized case converter uppercases the first letter of every word and leaves the remaining letters unchanged.
- Alternating Case Converter An alternating case converter switches every other letter between lowercase and uppercase, producing text that looks like tHiS.
- Inverse Case Converter An inverse case converter flips the case of every letter: capitals become lowercase and lowercase letters become capitals.

Why use this text converter
Most online text tools send what you paste to a server. This one does not. Every conversion is plain JavaScript running on your own machine, which has three consequences: it is instant (no network round trip), it is private (confidential drafts stay on your device), and it works offline once the page has loaded.
Each tool has its own page with worked examples, the style-guide rules that apply, and the edge cases that trip people up — because knowing that Chicago and APA disagree about title case matters more than another button.
Frequently asked questions
Is this text converter free?
Yes. Every tool is free with no sign-up, no account, and no usage limit.
Is my text uploaded to a server?
No. Every conversion runs in your browser using JavaScript. Your text never leaves your device, is never logged, and the tools keep working offline.
What is the difference between title case and sentence case?
Title case capitalises every major word in a headline, leaving short articles and prepositions lowercase. Sentence case capitalises only the first word of each sentence, the way ordinary prose is written.
Can I convert a large document?
Yes. There is no length limit, because the work happens on your device rather than on a server. Very large files may briefly pause the tab while converting.
