Title and Sentence case keep capitals of two to five letters, such as NASA, and common acronyms such as PDF. Letters follow English rules, so i becomes I, unless the Turkish option is on: then i becomes İ and I becomes ı.
This page opens the case converter with lower case selected, so every letter in your text becomes small as you type or paste. It fixes text typed with Caps Lock on, because the capitals come out as ordinary lower-case letters. The change happens on your device, and nothing is sent anywhere.
Lower case capitalises nothing, so names and the first letter of each sentence come out small too. After you convert, check those words. Names will still need a manual capital, but you can run the fixed text through sentence case to bring back the capital at the start of each sentence.
How to change the case of text
- Paste or type your text in the box.

Questions
Will it fix a whole paragraph at once?
Yes. The whole box is converted in one go, so paste a full paragraph or several lines, and the lower-case version appears at once.
What do I do with the result?
Copy it to paste into your document or message, or download it as a .txt file. Then check the names before you use it, since lower case leaves no capitals at all.
Which words stay lower case in Title Case?
Short words such as a, an, the, and, but, of, in, on and to stay lower case, unless they are the first or last word of a line. Each line is treated as its own title.
Why do PDF and NASA stay in capitals?
Title and Sentence case keep words of two to five capital letters, such as NASA, as they are. A short list of common acronyms, such as PDF, HTML and API, is capitalised even when typed in lower case. Text typed entirely in capitals is treated as shouting, so only that list is kept.
How are camelCase and snake_case worked out?
Each line is split at spaces, punctuation and changes from lower to upper case, so XMLHttpRequest is read as XML, Http and Request. Each line is converted on its own, so a list of names gives one identifier per line.
Is my text sent anywhere?
No. Conversion runs in your browser, and nothing is stored after you close the tab.
