Case Converter

Convert text between uppercase, lowercase, sentence case and more.

About this tool

The Case Converter helps you change text formatting instantly without retyping. You can convert content into uppercase, lowercase, sentence case, title case, and other common formats used in writing, documentation, and publishing. It’s ideal for cleaning copied text, formatting headings, preparing content for social media, or standardizing text in reports. Just paste your text, select the case style you want, and copy the converted result. This tool saves time and reduces mistakes, especially when handling long paragraphs or repeated formatting tasks across multiple pieces of content. For fixing only sentence starts (without changing other words), try Capitalize Sentences. If the text you pasted has messy spacing, use Remove Extra Spaces before converting.

How to Use This Tool

  1. Paste your text into the input area.
  2. Choose the case format you want (uppercase, lowercase, title case, sentence case).
  3. Copy the converted text.
