Convert text to uppercase, lowercase, title, or sentence case.
Clean up headings, captions, and copied text. Choose a case style and continue editing the result in the same field.
Convert an all-caps heading to a more readable style before using it in a draft. Review proper names and brand spellings afterward, because a mechanical case conversion does not know which words should keep special capitalization.
Apply one consistent style to captions, labels, or notes. Use the output as a starting point for editing rather than an automatic style-guide decision, especially when acronyms, abbreviations, or mixed-language text appear.
Title case capitalizes each whitespace-delimited word. Sentence case uses a simple punctuation rule, so check names and abbreviations after conversion.
hello WORLD
Title Case: Hello World. UPPERCASE: HELLO WORLD. lowercase: hello world.
Title case capitalizes a word's initial letter using a simple whitespace-based rule. It does not implement the editorial conventions of a particular style guide.
Case conversion works on character patterns rather than word meaning. Review and restore abbreviations, proper nouns, and intentional mixed-case spellings after using a conversion.
The tool uses a simple punctuation rule for sentence starts. Complex abbreviations, quotations, and unusual punctuation may need manual correction.
A little clarity before you get started.

No. It changes capitalization only. Review the text separately for spelling, punctuation, names, and meaning.
There is no dedicated history panel. Keep a copy of your original text before applying changes, particularly when its capitalization carries meaning.
