Questions
Why does i turn into I and not İ?
English letter rules apply by default, so i becomes I. The Turkish and Azerbaijani option on the page makes i become İ and I become ı. It is off unless you switch it on.
Does the page count my characters?
Yes. The page shows a count of lines changed and characters for your text, so you can check the length before you copy it.
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.
