What this tool does
Change capitalization without retyping text. Choose uppercase, lowercase, title case, sentence case or alternating case, then copy the transformed result.
Case conversion is useful for cleaning copied headings, spreadsheet exports and social drafts. Automated title case is a formatting aid rather than a language editor, because different style guides treat short words, proper nouns and acronyms differently.
Useful for
- Normalize text copied from all-caps documents.
- Create headline-style capitalization for drafts.
- Clean inconsistent capitalization in lists and labels.
How to use it
- Paste the text into the input area.
- Choose the case style you need.
- Review names, acronyms and brand terms manually.
- Copy the converted result.
Practical tips
- Check proper nouns after automatic conversion.
- Do not use all caps for long passages because it can reduce readability.
- Sentence case is often easiest to read for interface labels and body text.
- The conversion happens locally in your browser.
Frequently asked questions
Does title case follow a specific style guide?
It uses a practical general rule set, not a strict AP, Chicago or MLA implementation.
Will acronyms stay uppercase?
Some transformations may change them, so review acronyms and branded capitalization before publishing.
Can I undo a conversion?
The original input remains available until you replace it or clear the page, so you can choose another conversion at any time.
