Fixing inconsistent capitalization without retyping
Pasting text from different sources often leaves you with a messy mix of ALL CAPS headings, lowercase sentences, and random Title Case fragments. This converter normalizes everything in one pass so you can ship clean copy into documents, emails, or code. Writers, developers, and data entry teams use it to reformat imported CSV fields, correct shift-key mistakes, and prepare consistent UI labels. Four modes cover the common formatting standards without manual editing.
Frequently Asked Questions
What does the case converter do?
It changes the capitalization of any text — UPPERCASE, lowercase, Title Case or Sentence Case — while leaving your punctuation, spacing and line breaks exactly as they were.
Which case styles can I convert to?
Four: UPPERCASE, lowercase, Title Case (every major word capitalized) and Sentence case (only the first word of each sentence).
Will it keep my line breaks and punctuation?
Yes. Only the letter casing changes. Commas, punctuation, paragraph breaks and the original layout are preserved, so the converted text can be pasted straight back into your document.
Is the case converter free and private?
It is completely free with no sign-up, and all conversion happens inside your browser — the text you paste is never uploaded or stored.
See one string in all four cases
Every page takes a single string and shows what UPPERCASE, lowercase, Title Case and Sentence case each return, letter for letter, so nothing changes behind your back.
