Case Converter

Need to fix text that was typed in the wrong case? A case converter extension puts formatting control right where you work. Change any selection to lower case, UPPER CASE, Title Case, Sentence case, or other styles from the right-click menu or in the side panel. All changes happen on your device—nothing is sent to a server.

🛠 What you can do

The extension works as an uppercase to lowercase converter and more. Use it to turn ALL CAPS into normal text, apply Title Case to headings, fix pasted text that came in the wrong case, and switch between lower and upper case quickly. You can also use formats like camelCase or snake_case when you need them. No copy-paste into external sites; the case converter runs in your browser.

1. Select text on any webpage or in any input field

2. Open the context menu or the side panel

3. Pick the format you want (lower case, UPPER CASE, Title Case, and others)
