Case Converter & Text Cleaner
Change text to upper, lower, title, sentence, camel or snake case, and clean up extra spaces, blank lines and line breaks — instantly, in your browser.
In short
Sentence case capitalises the first letter of each sentence and the pronoun I; Title Case capitalises every word except short joining words (a, and, of, the) in the middle; camelCase, PascalCase, snake_case and kebab-case are for code and file names; a url-slug is lowercase ASCII with hyphens.
Who this is for: Writers, students, developers and marketers fixing capitalisation or cleaning pasted text.
What each case does
- Sentence case — first letter of each sentence capital, the rest lower; "i" is capitalised. The fix for text typed in caps lock.
- Title Case — capitalises every word except short joining words (a, and, of, the…) in the middle, the convention for headlines and titles.
- Capitalize Each Word — every word, no exceptions: names, product lists.
- camelCase / PascalCase / snake_case / kebab-case — for variable and file names; the converter splits existing camelCase and underscores first.
- url-slug — lowercase, accents removed, non-alphanumerics dropped, spaces to hyphens: ready for a web address.
Clean-up options handle the usual copy-paste mess: double spaces, blank lines, hard line breaks from PDFs and emails, and stray punctuation. Urdu, Arabic and other non-Latin text passes through unchanged (they have no letter case).

Assumptions
- Clean-up (punctuation, join lines, blank lines, spaces) runs before the case change.
- Title Case keeps a short list of joining words lower-case except at the start and end.
- camel/Pascal/snake/kebab split on spaces, hyphens, underscores and existing camelCase boundaries.
Worked example
Input: FINAL SETTLEMENT OF END-OF-SERVICE
BENEFITS UNDER THE LABOUR LAW
Join lines + collapse spaces + Title Case → Final Settlement of End-of-Service Benefits Under the Labour Law; url-slug → final-settlement-of-end-of-service-benefits-under-the-labour-law.
Frequently asked questions
How do I fix text typed in all caps?
Choose Sentence case — it lowercases everything and recapitalises sentence starts and the pronoun I. Proper nouns will need a manual check.
Does it work on Urdu or Arabic?
Those scripts have no upper or lower case, so case modes leave them as they are; the clean-up options (spaces, lines, punctuation) still work.
Is my text stored?
No — conversion runs in your browser; nothing is sent anywhere.
Can I convert a Word document?
Paste the text here, convert, and paste back; formatting (bold, links) is not carried through.
How do I change all caps to normal text?
Paste the text and choose Sentence case.
What is title case?
Capitalising the main words of a title and leaving short joining words like 'of' and 'the' in lower case.
