About this tool

About Text Case Converter

The Text Case Converter changes the capitalisation of your text in one click. Convert to UPPERCASE, lowercase, Title Case, Sentence case and other common formats without retyping anything.

It is handy for fixing text typed with caps lock on, formatting headings, preparing titles for articles or tidying imported data. Because rules for title case differ between style guides, check important headlines by eye after converting.

Text arrives in the wrong case more often than you would expect: headings pasted in capitals, titles in lowercase, or names that need consistent formatting. The Case Converter changes text to uppercase, lowercase, title case, sentence case and similar formats in one click.

Automatic conversion is a fast first pass. Names, acronyms and brand spellings sometimes need a manual check afterward, because a tool cannot know that a word is meant to keep unusual capitalization.

Frequently Asked Questions

Which case formats are supported?
You can convert text to uppercase, lowercase, title case, sentence case and other listed styles using the buttons in the tool.
What is the difference between title case and sentence case?
Title case capitalises the main words in a heading, while sentence case capitalises only the first word and proper names.
Will it handle names and acronyms correctly?
Automatic conversion cannot know every name or acronym, so check those manually after converting.
Does the converter change punctuation or spacing?
The tool focuses on letter case. Punctuation and spacing are left as you entered them.
Can I convert a large document?
Yes, within the limits of your browser. Very large texts are better converted in sections.
Is my text stored?
No. Conversion happens in your browser and the text is not sent to a server.
