Flip Caps is a free online text case converter. You paste any text into the tool, click a button, and it instantly converts your text into the case style you choose, all inside your browser with no sign-up required.

What is a text case converter?

A text case converter is a tool that changes the capitalization style of any text. Instead of manually retyping content, you paste it in and choose a style like UPPER CASE, lower case, or Title Case, and the tool transforms it for you in a single click.

What case styles does Flip Caps support?

Flip Caps supports seven case styles: Sentence case (capitalizes the first letter of each sentence), lower case (all lowercase), UPPER CASE (all capitals), Capitalized Case (first letter of every word), aLtErNaTiNg cAsE (alternates each letter), Title Case (proper title capitalization), and InVeRsE CaSe (flips existing capitalization).

Is Flip Caps free to use?

Yes. Flip Caps is completely free. There is no subscription, no sign-up, no trial, and no paywall. You can convert as much text as you want at no cost.

Is my text private when I use Flip Caps?

Yes, 100%. Flip Caps runs entirely in your browser using JavaScript. Your text is never sent to any server, never stored, and never seen by anyone. Everything happens locally on your device.

Is there a character limit?

No. Flip Caps has no character limit. You can paste an entire essay, article, email, or document and it will convert the full text without any restrictions.

Can I download the converted text?

Yes. After converting your text, click the Download button in the toolbar to save the result as a plain .txt file directly to your device.

Can I use Flip Caps as a capital text generator?

Yes. Flip Caps is a great capital text generator. Click UPPER CASE to convert every letter to a capital, or click Capitalized Case to capitalize only the first letter of each word. Both options work instantly with no character limit.

What is the difference between UPPER CASE and Capitalized Case?

UPPER CASE converts every single letter to a capital (e.g. 'hello world' becomes 'HELLO WORLD'). Capitalized Case only capitalizes the first letter of each word (e.g. 'hello world' becomes 'Hello World'). Choose UPPER CASE for emphasis or headings; choose Capitalized Case for names and branded terms.

What is Sentence case and when should I use it?

Sentence case capitalizes only the first letter of each sentence and lowercases everything else, just like normal written English. Use it to fix text that was pasted in the wrong format, or to quickly normalize inconsistently capitalized content.

What is Title Case and when should I use it?

Title Case capitalizes major words in a title while keeping short connecting words (a, an, the, and, but, or, for, in, of, etc.) in lowercase. It follows standard English title-writing conventions. Use it for article headlines, blog post titles, book chapters, and page headings.

What is alternating case?

Alternating case (aLtErNaTiNg cAsE) switches every letter between lowercase and uppercase, the first letter is lowercase, the second uppercase, the third lowercase, and so on. It is mostly used for memes, social media humor, and informal creative text.

What is Inverse case?

Inverse case (also called toggle case or flip case) swaps the capitalization of every letter, uppercase letters become lowercase and lowercase letters become uppercase. For example, 'Hello World' becomes 'hELLO wORLD'. It is useful for quickly reversing the case of text that was typed with Caps Lock accidentally on.

How do I fix text that was accidentally typed in ALL CAPS?

Paste the all-caps text into Flip Caps and click Sentence case to convert it to normal capitalization, or click lower case to make everything lowercase first. This is much faster than retyping the entire text.

Does Flip Caps work on iPhone and Android?

Yes. Flip Caps is fully responsive and works on any device, iPhone, Android, tablet, desktop, or laptop. The interface adapts to smaller screens and all case conversion buttons are touch-friendly.

Does Flip Caps require an account or sign-up?

No. Flip Caps requires no account, no sign-up, no email address, and no password. You open the website and the tool is immediately ready to use.

What browsers does Flip Caps work in?

Flip Caps works in all modern browsers including Google Chrome, Safari, Firefox, Microsoft Edge, Opera, and Brave. It requires JavaScript to be enabled, which it is by default in all browsers.

How do I copy the converted text?

After converting your text, click the Copy button in the toolbar above the text area. A confirmation checkmark appears to confirm the text has been copied to your clipboard. You can then paste it anywhere.

What is the difference between Title Case and Sentence Case?

Title Case capitalizes the first letter of every major word (used for headings and titles). Sentence Case only capitalizes the first letter of the first word in each sentence (used for normal written text). For example, 'the quick brown fox' becomes 'The Quick Brown Fox' in Title Case but 'The quick brown fox' in Sentence Case.
