Case Converter
Convert any text between UPPERCASE, lowercase, Title Case, Sentence case and more — in one click. Fix accidental caps lock, format headings properly, and clean up messy spacing. Everything runs privately in your browser.
How to use this case converter
Paste your text, press a button, and the whole text changes case instantly. Sentence case capitalises the first letter of every sentence — ideal for fixing text typed in all caps or all lowercase. Title Case capitalises the first letter of every word, the way book titles and blog headings are written.
Remove extra spaces tidies text copied from PDFs and documents: double spaces collapse to one, ragged lines are trimmed, and big empty gaps shrink. The counter under the buttons always shows your current word and character count.
Need the counts in detail instead? The word counter adds sentences, reading time and top keywords. Both tools — like all our free tools — run entirely on your device.
Frequently Asked Questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word ("The Quick Brown Fox"). Sentence case capitalises only the first letter of each sentence ("The quick brown fox.").
I typed everything in CAPS by mistake. Can this fix it?
Yes — paste the text and press "Sentence case" (or "lowercase" first, then "Sentence case") and it becomes normal readable text.
Is my text uploaded anywhere?
No. The conversion happens in your browser with JavaScript; nothing is sent to a server.
Does it work for Hindi and other languages?
The case buttons affect languages that have upper and lower case letters (English and most European languages). Scripts like Devanagari have no letter case, so they pass through unchanged.
