Case Converter
Every writer has done it: typed a whole heading with Caps Lock on, pasted a title that arrived in SCREAMING CAPITALS, or needed a paragraph converted to Title Case for a document style guide — and then retyped it by hand. This free case converter fixes text case in one click. Choose UPPERCASE, lowercase, Title Case, or Sentence case, and copy the cleaned result straight back into your document. Like every tool on this site, it runs entirely in your browser, so the text never leaves your device.
Who it is for: writers, students, social media managers, programmers tidying up pasted text, and anyone fixing a Caps Lock accident. Example: a colleague emails a product list typed entirely in capitals. Paste it in, click Sentence case for readable lines — or Title Case if it is destined for a catalogue heading — copy, and you are done in seconds instead of retyping forty items.
How to Use the Case Converter
- Paste or type your text in the box.
- Click the case you need. UPPERCASE shouts; lowercase calms everything down; Title Case capitalises the first letter of every word, the style used for headings and titles; Sentence case capitalises only the first letter of each sentence, like normal prose.
- Click Copy result and paste the converted text wherever it needs to go.
Frequently Asked Questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of nearly every word ("The Quick Brown Fox"), which suits headlines and titles. Sentence case capitalises only the first word of each sentence ("The quick brown fox"), which suits ordinary paragraphs and descriptions.
Does Title Case handle small words like "the" and "of"?
This converter capitalises every word for predictability, including small joining words. Formal style guides (such as AP or Chicago) lowercase short prepositions and articles inside a title; if your publication follows one, adjust those few words by hand after converting.
Will converting case fix my spelling or grammar?
No — the converter changes only letter case, never the words themselves. For word and sentence counts, pair it with our Word Counter.
Is there a limit on how much text I can convert?
There is no set limit; the converter handles whole documents comfortably because it runs locally. Very large pastes (an entire book chapter) may take a moment on older devices.
