When You'd Use This

Caps lock oops

You typed a whole paragraph before noticing caps lock was on. Fix it in one click instead of retyping.

Need Title Case for a blog post, book title, or slide? Paste it and convert. Same for sentence case in body copy.

Formatted lists

Spreadsheet exports, CSV data, or plain lists. Capitalized Case keeps things neat without manual edits.

Social and creative

aLtErNaTiNg cAsE or InVeRsE CaSe for a tweet, username, or design mockup. Quick, no fuss.

Common Questions

How do I fix text that was typed with caps lock on?

Paste your text into the case converter and click "lower case." It converts everything in one click. If you want the first letter of each sentence capitalized instead, use "Sentence case."

What's the difference between sentence case and title case?

Sentence case capitalizes the first letter of each sentence; everything else stays lowercase. Title case capitalizes the first letter of most words (nouns, verbs, adjectives) but leaves small words like "a," "the," and "and" lowercase unless they start or end the title. Use sentence case for paragraphs; use title case for headlines and book titles.

Is this case converter free?

Yes. No signup, no limits. Paste, convert, copy. That's it. Everything runs in your browser, so we don't store or see your text.

Does it work with accents and non-English characters?

Yes. The tool handles Unicode, so accents (é, ñ, ü, etc.) and characters from other languages work correctly. Case conversion only affects letters; numbers and punctuation stay as-is.

When would I use alternating case or inverse case?

Alternating case (aLtErNaTiNg) and inverse case (fLIP eVERYTHING) are mostly for creative or playful text: social posts, usernames, or design mockups. Inverse case flips whatever case you have: uppercase becomes lowercase and vice versa. Handy if you pasted something and realized you wanted the opposite.
