CaseConvert.ing Browser Extensions - Text Conversion on Any Webpage
Browser extensions for Chrome, Firefox, and Edge that let you convert text case and format text directly on any webpage. Right-click any selected text to convert it instantly.
The CaseConvert.ing browser extension brings all our text tools directly to any page you are reading, without opening a new tab or copying and pasting. Select text, right-click, and convert. It is that simple.
What the extension does
| Feature | How it helps |
|---|---|
| Right-click context menu | Highlight any text on a webpage, right-click, and choose a conversion from the menu. The text changes in place with no extra steps. |
| Clipboard copy option | Enable Auto-Copy to push the converted result straight to your clipboard. Useful when you cannot edit the text in place, such as on read-only pages. |

| Keyboard shortcuts | Assign hotkeys to your favourite conversions in the extension settings and convert text without touching the mouse. |

Which browsers will the extension support?
We are building extensions for Google Chrome, Mozilla Firefox, and Microsoft Edge. All three are based on the same codebase and will have identical features. Safari support may follow in a later release.
Does the browser extension work offline?
Yes. All text processing happens locally in your browser. The extension does not send your text to any server. It works without an internet connection once installed.
Will I need an account to use the extension?
No. The extension requires no sign-up, no account, and no login. Install it and it is ready to use immediately.
Can I use keyboard shortcuts with the extension?
Yes. You will be able to assign custom keyboard shortcuts to your most-used conversions through the extension settings. This is designed for users who want to convert text without touching the mouse at all.
Will the extension work on Google Docs or Notion?
Support for rich-text editors like Google Docs, Notion, and similar tools is more complex because they use custom text rendering. We are working on compatibility but cannot guarantee it in the initial release. Standard text fields on most websites will work without issues.
How do I give feedback or report a bug?
Email hello@caseconvert.ing with details about the issue. Include your browser name and version, which site you were on, and what happened. Screenshots help a lot.
