Features & Capabilities

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.

User Reviews

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).

Recent reviews

Great extension, but its missing the shortcut configuration for the other things available in the context menu. Specifically sentence case, which is the most useful, and alternative case for the uses of mocking someone. :3

It works which is what we all want. Thanks for the Addon.

Can you make a shortcut for example - Alt+1 - for Sentence case too? (but not Alt+S, this activates the help menü in my browser :) )

Is Convert Case Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Convert Case requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Convert Case is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
