Fix text typed in the wrong case
Text written with Caps Lock on, headings with random capitals, or names in all lowercase can be fixed in one step. Sentence case puts a capital at the start of each sentence. Title Case capitalizes the main words of a heading and keeps short words like "and", "of" and "the" small.
Capitalize Each Word puts a capital on every word, which suits names and labels.
Cases for code and file names
camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case join words for programming, URLs and file names. Each line is changed on its own, so you can convert a whole list of names at once.
Questions
Is my text uploaded?
No. The text is changed inside your browser and never leaves your device.
Does it work with accented letters?
Yes. Letters like é, ü and ñ and other alphabets such as Greek and Cyrillic are changed correctly.
Will Sentence case keep names capitalized?
No tool can know every name. Sentence case keeps acronyms and common abbreviations, capitalizes sentence starts and keeps the word "I" uppercase; check names afterwards.
