Text Case Converter

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

1. Paste the text into the input area.
2. Choose the case style you need.
3. Review names, acronyms and brand terms manually.
4. Copy the converted result.

Worked examples

Common mistakes to avoid

• Publishing automatic title case without checking brand names, product names and acronyms that use intentional capitalization.
• Using uppercase for long passages, which can make text harder to scan and read.
• Assuming title case is identical across AP, Chicago, MLA and an organization’s own editorial style.

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.
