Case converter questions answered
How do I change uppercase to lowercase?
Paste or type your text into the box and click lower case. The whole text is converted instantly and you can copy it with one click.
What is sentence case?
Sentence case capitalises only the first letter of each sentence and leaves the rest lowercase, like normal writing. It is the easiest style to read for body copy.
What is the difference between title case and Capitalize Each Word?
Capitalize Each Word capitalises the first letter of every word. Strict title case style guides leave small words such as "and" and "of" in lowercase, so check the result against your style guide for formal headings.
Does it keep my text private?
Yes. The conversion happens in your browser and your text is never sent or stored.
Can I undo a conversion?
Yes. Use the Undo button to step back one change, or paste your text again.
What case should I use for SEO titles and URLs?
Page titles read best in title case or sentence case, and URLs should always be lowercase with hyphens between words to avoid duplicate pages.
