Text Case Converter
Convert text to UPPER CASE, lower case, Title Case, or Sentence case instantly.
About this tool
Copied text often arrives in the wrong case — all caps from a spreadsheet header, inconsistent capitalisation from a form export, or title case when you need sentence case. This tool converts any text to upper case, lower case, title case or sentence case with one click.
How to use
Paste the text into the input box, choose the target case from the dropdown, and click Run. The converted text appears in the output box ready to copy.
When to use this tool
Use this when cleaning up headings from a CMS export, normalising data from form submissions, converting all-caps text copied from a PDF, or preparing text for publishing with consistent capitalisation.
Privacy
All conversion happens locally in your browser. No text is sent to a server or stored anywhere.
Frequently asked questions
What is Title Case?
Title Case capitalises the first letter of every word. For example: The Quick Brown Fox Jumps Over The Lazy Dog.
What is Sentence case?
Sentence case capitalises only the first letter of the first word in each sentence, and lowercases everything else. It is the standard capitalisation for most body text.
Does it handle accented characters?
Yes. The converter uses JavaScript's built-in locale-aware methods which correctly handle accented and non-ASCII characters for common European languages.
