Convert Text Case

The Case Converter is a powerful online tool for automatically converting text into different writing styles. Whether you want to convert text completely to uppercase or lowercase, capitalize each sentence beginning, or start each word with a capital letter – this tool does it in seconds.

Our free case converter supports various text formats and writing styles needed in different contexts. From classic sentence case to title case to special formats like alternating or inverted case, the tool offers all common options. Perfect for content creators, authors, social media managers, and anyone who regularly works with text formatting.

Correct capitalization is crucial in text processing for professionalism and readability. You often receive texts in inconsistent formats – perhaps completely in uppercase from an old database, or without any capitalization from a chat. Manual correction of such texts is time-consuming and error-prone.

Our tool is particularly valuable when working with imported data, copied texts, or legacy systems. In many older databases, names and addresses were stored completely in uppercase. With the case converter, you quickly normalize this data for modern applications. The tool is also indispensable for social media posts, where different writing styles are sometimes deliberately used.

Content creators use the converter for quick formatting of headings, subheadings, and text blocks. Developers appreciate the ability to quickly switch between different naming conventions. Students and academics use the tool for correct formatting of titles and references in academic papers.

The Case Converter offers six different conversion options: UPPERCASE converts every letter to capitals, ideal for headings or emphasis. lowercase converts everything to lowercase, useful for URLs or uniform file names. The "Capitalize Each Word" option (Title Case) capitalizes the first letter of each word – perfect for titles and headings.

Sentence case ensures that only the first letter of each sentence is capitalized while the rest remains lowercase – ideal for normalizing body text. Alternating case (aLtErNaTiNg) switches between upper and lowercase and is suitable for creative texts or social media posts. Inverted case (iNVERT cASE) completely reverses capitalization – uppercase becomes lowercase and vice versa.

All conversions occur in real-time directly in your browser. Your texts are not uploaded or stored, guaranteeing maximum privacy. With the integrated copy function, you can transfer the result to your clipboard with one click and use it immediately in your application.
