Frequently asked questions
Which conversion modes are available?
The converter supports five modes: uppercase (all caps), lowercase (all small), title case (every word starts with a capital), sentence case (only sentence starts are capitalized) and toggle case (alternating upper and lower).
What is the difference between title case and sentence case?
In title case every word starts with a capital letter, which suits headings and titles. In sentence case only the first letter of a sentence is capitalized while the rest stays lowercase.
What does the toggle case mode do?
Toggle case writes the characters in alternating upper and lower case. It is great for eye-catching social media posts or creative captions.
Can I copy the converted text directly?
Yes. The conversion happens in real time and the converted text appears immediately, ready to copy with a single click.
Is my text sent to a server?
No. The conversion runs entirely in your browser, and your text is not transmitted to our server or stored.
What is the case converter useful for?
It helps you standardize headings, clean up imported data, create eye-catching texts, ensure correct spelling for accessibility and convert variable or constant names in programming.
