## Description

Convert Case is a Chrome extension that lets you transform text directly in any webpage. Select text, right-click, and convert it in place to UPPER CASE, lower case, sentence case, title case, and more—without leaving the page. Enable **Copy After Conversion** in the context menu to automatically copy the result to your clipboard.

Highlights include keyboard shortcuts (Alt+U, Alt+L, Alt+C, Alt+A) or customizable keys, a Slugify option for URL-friendly text, and broad compatibility with Google Docs, Reddit, Disqus, WYSIWYG editors, and iframe-based content. The extension has seen regular updates to improve reliability and expand compatibility.

## Review summary

Users broadly praise Convert Case for reliability and time-saving benefits across text and forms, especially for editors and developers. However, two recurring issues limit appeal: the absence of customizable keyboard shortcuts for capitalization options, and the absence of Title Case (with requests for adding it). These recurring points are the most mentioned constraints despite the overall positive sentiment.

### Pros

- Works reliably and as expected across multiple use cases.
- Saves time and improves editing workflow for capitalization tasks.
- Generally regarded as an excellent and valuable extension for editors and developers.

### Cons

- Lacks configurable keyboard shortcuts / shortcut configuration for capitalization options (e.g., sentence case; requests for Alt+1, etc.).
- Missing Title Case support and shortcuts for Title Case (frequent user request).
