Text Case Converter
Convert text to uppercase, lowercase, title case, or sentence case online in your browser without uploading your text to a server.
What this tool does
NexKit Text Case Converter converts text between UPPERCASE, lowercase, Title Case, and Sentence case, entirely in your browser, updating live as you type.
Title Case capitalizes the first letter of every word. This is a simple, predictable rule rather than an attempt to follow a specific style guide (AP, Chicago, etc.), which disagree on which short words to leave lowercase.
How to convert text case
Paste or type your text, then choose a case from the buttons above the result. The converted text appears immediately and can be copied with one click.
Privacy and file handling
Your text is converted entirely in your browser. It is not uploaded to NexKit servers by this tool.
