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.

What is a duplicate word finder?

A duplicate word finder is a free online tool that scans your text and identifies every word that appears more than once. The results are sorted by frequency so you can instantly see which words you are overusing most.

How do I find repeated words in my text?

Paste or type your text into the input field. The tool instantly scans it and lists all words that appear more than once in the right panel, sorted from most repeated to least repeated.

Why is finding duplicate words useful?

Repeated words make writing sound monotonous and unprofessional. Spotting overused words lets you replace some with synonyms, tighten your prose, and improve readability in blog posts, essays, emails, and other written content.

Is the word detection case-sensitive?

You can choose. In case-insensitive mode (default), 'The', 'the', and 'THE' all count as the same word. In case-sensitive mode they are counted separately.

What are stop words and should I ignore them?

Stop words are very common words like 'the', 'a', 'and', 'is', 'in', 'of', and so on. Because they appear in almost every sentence, they are almost always the most repeated words. Enable 'Ignore stop words' to hide them and focus on the meaningful content words you are actually overusing.

Can I set a minimum word length?

Yes. Use the minimum length filter to ignore very short words. For example, setting it to 4 hides words like 'a', 'to', 'the', and 'and', letting you focus on longer content words.

Is there a limit on how much text I can analyse?

No. The tool handles text of any length, a paragraph, an entire blog post, or a full essay. All processing happens in your browser with no server-side limit.

Yes, 100%. All analysis runs entirely in your browser. Your text is never uploaded to any server, never stored, and never seen by anyone else.

Yes. The duplicate word finder is completely free with no subscription, no sign-up, no trial, and no paywall.

Can I copy or download the word frequency results?

Yes. Click Copy to copy the results list to your clipboard, or Download to save it as a plain .txt file directly to your device.

Does punctuation affect the word count?

No. The tool strips punctuation before counting, so 'word', 'word,' and 'word.' are all counted as the same word.

Can I use this on mobile?

Yes. The tool is fully responsive and works on iPhone, Android, tablet, and any desktop or laptop browser.

Do I need an account?

No. No account, no sign-up, no email, no password required. Open the page and start using it immediately.

How are the results sorted?

Results are sorted by frequency in descending order, the most repeated word appears at the top, the least repeated at the bottom. Words with the same count are sorted alphabetically.

What counts as a 'word'?

Any sequence of letters and numbers separated by spaces or punctuation. Punctuation attached to a word (like a comma or period) is stripped before counting, so 'hello,' and 'hello' are the same word.
