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 Sentence case selected. The first letter of each sentence becomes a capital. Capitals of two to five letters, such as NASA, stay as they are, and common acronyms such as PDF, HTML and API are capitalised even when you type them in lower case.
Sentence case suits body text, captions and headings written as full sentences. For headings made of short phrases, where each main word takes a capital, use title case instead.

Questions
What do I copy or download after converting?
Copy puts the converted text on your clipboard. Download .txt saves it as a plain text file. Check the result before you use it, since the rules are fixed.
Does Sentence case keep acronyms as they are?
Yes, for capitals of two to five letters and for the common acronyms on the page's list. Other words follow sentence style, so check any name you need capitalised after you convert.
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.
