Question 1

What is a text case converter?

Accepted Answer

A tool that changes the capitalisation of any block of text in a single click — no software needed, no account required. Paste your text, choose a format, and copy the result.

Question 2

Is Convert Case Online free?

Accepted Answer

Yes, completely free — now and always. No premium plans, no sign-up, and no limits on how much text you convert.

Question 3

Does my text get sent to a server?

Accepted Answer

No. Every conversion runs in your browser using JavaScript. Your text never leaves your device, is never logged, and is never stored.

Question 4

Is there a character limit?

Accepted Answer

No enforced limit. It handles thousands of words instantly on any modern device, because the work happens locally rather than over a network.

Question 5

Does it work on mobile?

Accepted Answer

Yes. The site is fully responsive and works on smartphones and tablets in any modern browser, including the copy and share buttons.

Question 6

Do I need to install anything?

Accepted Answer

No. It runs entirely in the browser. You can also add it to your home screen as a web app if you use it often.

Question 7

What is Sentence case?

Accepted Answer

Sentence case capitalises only the first letter of each sentence and leaves everything else lowercase — like normal written English. It is the modern default for headings in product and documentation writing.

Question 8

What is the difference between Title Case and Capitalized Case?

Accepted Answer

Capitalized Case capitalises every word without exception. Title Case follows editorial rules — short words like "a", "the", "and", and "in" stay lowercase unless they start or end the title. Use Title Case for headlines and Capitalized Case for names and short labels.

Question 9

What is alternating case?

Accepted Answer

Alternating case switches between lowercase and uppercase for each letter (aLtErNaTiNg). It is the mocking SpongeBob meme font, used online to convey sarcasm.

Question 10

What does Inverse Case do?

Accepted Answer

Inverse case flips every character — uppercase becomes lowercase and lowercase becomes uppercase. It is useful for undoing a caps-lock mistake where the shift key was also used.

Question 11

What is the difference between camelCase and PascalCase?

Accepted Answer

They are identical except for the first letter. camelCase starts lowercase (userName) and is used for variables and functions; PascalCase starts uppercase (UserName) and is used for classes, types, and components.

Question 12

When should I use snake_case instead of kebab-case?

Accepted Answer

Use snake_case in code — underscores are valid in identifiers in nearly every language. Use kebab-case in URLs, CSS class names, and file names, where hyphens are the convention and search engines read them as word separators.

Question 13

How do I copy the converted text?

Accepted Answer

Click the copy icon in the toolbar below the text box. A confirmation appears once the text is on your clipboard.

Question 14

Can I download the result?

Accepted Answer

Yes — click the download icon to save the converted text as a .txt file to your device.

Question 15

What do the counts show?

Accepted Answer

Character count (including spaces), word count, and line count — all update in real time as you type or convert.

Question 16

Can I convert a whole list at once?

Accepted Answer

Yes. Paste one item per line and convert. Line breaks are preserved, and the developer formats convert each line independently, so a full column of names converts in a single click.

Question 17

Can I undo a conversion?

Accepted Answer

The tool converts in place, so use your browser's undo shortcut in the text box, or convert back to the previous format. Copy important text before converting if you need to keep the original.
