What this tool does
Converts the letter case of text between the common forms — upper case, lower case, sentence case, title case and others.
When to use it
- A heading typed in all capitals that you want in proper title case.
- Text that arrived in inconsistent case you want normalised.
- Lower-casing text before processing it programmatically.
- Preparing a headline for publication in a consistent form.
How to use it
- Choose the "Case conversion type".
- Paste your text into the field.
- Copy the "Result".
A practical example
Input
A phrase in all capitals converted to title case.
Output
The same phrase with each principal word capitalised.
Limitations
- The conversion affects Latin letters only: scripts that draw no distinction between upper and lower case — Arabic among them — are left unchanged, which is a property of those scripts rather than a fault.
- Title case follows a general rule and may not match the style guide your organisation uses for articles and prepositions.
- Names and acronyms can lose their correct form after conversion; review the output.
Privacy and processing
The conversion happens on your device and your text is never sent anywhere.
Technical notes
- The in-tool notice about Latin letters exists specifically because an Arabic-speaking user might otherwise think the tool is broken, when it is converting everything that can be converted.
