The Case Converter Tool Chrome extension is a free browser extension that changes the case of text on any web page. Select the text, right-click and choose a format such as UPPER CASE, Title Case, camelCase or snake_case. It needs no sign-up, and the developer states it processes text locally.
It is the browser companion to the Case Converter website. The website is best for long text you paste into a box. The extension is best for the small fixes you meet while you read or write on other sites.

It takes four steps after the install.
Open the Chrome Web Store listing and select Add to Chrome. Chrome shows any permissions the extension asks for. Read them before you approve.
Highlight the words you want to change in an article, an email, a form or a document. The extension works on the text you select.
Open the browser right-click menu on the highlighted text and look for the Case Converter Tool entry.
Choose UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case or kebab-case from the menu.
The Web Store listing names eight formats. Four are for writing and four are for code. The table applies each one to the same phrase, so you can see exactly what changes.
The uppercase converter, lowercase converter and sentence case converter pages explain the writing formats in more depth.
| Format | Result | Often used for |
|---|---|---|
| UPPER CASE | MY PROJECT NAME | Headings, acronyms and fixing text typed with Caps Lock on |
| lower case | my project name | Normalising pasted text, email addresses and search terms |
| Title Case | My Project Name | Headlines, titles and button labels |
| Sentence case | My project name | Body text, captions and ordinary sentences |
| camelCase | myProjectName | Variable and function names in JavaScript and Java |
| PascalCase | MyProjectName | Class and type names in many languages |
| snake_case | my_project_name | Variable and file names in Python and SQL |
| kebab-case | my-project-name | URL slugs and CSS class names |
The listing calls it a toolkit, not only a case changer. These are the other tools it names. Each one has a full page on the website with examples and an FAQ.
Tiny, superscript, mirror and Wingdings text, built on the same engines as the tiny text generator, superscript generator, mirror text generator and Wingdings translator pages.
A paragraph to single line converter and a remove text formatting tool for pasted text.
A Lorem Ipsum generator, a phonetic spelling generator and an HTML to hyperlink converter.
A random password generator for strong passwords and PINs.
The online time, age, expense, significant figures and sleep calculators.
Both are free, and neither asks you to sign up. They suit different moments. The extension saves a trip to another tab. The website gives you more room and more feedback.
Many people use both: the extension for a quick fix in the middle of a task, and the case converter website when the text is long or needs checking.

These steps follow Chrome official help pages and apply to any extension.
Open the listing and select Add to Chrome. Chrome asks you to approve any permissions it needs, then the extension is ready to use.
Select the Extensions icon (the puzzle piece) next to the address bar, find the extension and select Pin so it stays visible.
Chrome does not add extensions while you browse in Incognito. For an extension you already have, open its Details in Manage extensions and turn on Allow in incognito.
Open the three-dot menu, go to Extensions, then Manage extensions. Use the toggle to switch it off, or right-click its icon and select Remove from Chrome.
A right-click case converter normally needs a way to add items to the context menu. Depending on how it is built, it may also need access to the tab you are using or to the clipboard. Chrome lists each permission and any warning it shows.
The table shows what these common permissions mean, from Chrome's permissions list. It is general background, not a list of what this extension requests. When you select Add to Chrome, Chrome shows the exact permissions requested. Read that prompt before you approve it.
| Permission | What it allows | Chrome warning |
|---|---|---|
| contextMenus | Lets an extension add items to the right-click menu. Chrome lists contexts such as selected text and editable fields. | No warning listed in Chrome table |
| activeTab | Gives temporary access to the tab you are using after you do something such as click the extension. | No warning listed in Chrome table |
| clipboardWrite | Lets an extension copy or cut items to the clipboard. | Modify data you copy and paste |
| clipboardRead | Lets an extension paste items from the clipboard. | Read data you copy and paste |
The Chrome Web Store listing says the developer will not collect or use your data, and that text is processed locally and is not stored, tracked or shared. It also declares that data is not sold to third parties outside approved uses, and is not used for unrelated purposes or for lending decisions.
Those are the developer statements, and you should read the listing yourself. Chrome Web Store policy also bars extensions from using user data for personalised advertising or selling it. Our privacy policy explains how the website and the extension handle information.
The listing names writers, developers, students and social media managers. Here is how each might use it.
Fix a headline typed in capitals or put a title into Title Case without leaving the page.
Tidy notes and assignment headings, or turn copied sentences into sentence case.
Turn a phrase into camelCase, PascalCase, snake_case or kebab-case for a name or a URL slug.
Adjust the case of captions and posts while you work in the browser.
Rescue a whole paragraph typed in capitals without retyping it.
Make pasted names and labels consistent before they go into a form or sheet.
Every browser extension has limits. These are the ones to keep in mind, so you are never surprised.
Many web apps and online editors replace the browser right-click menu with their own. If you do not see the extension there, select the text and use the Case Converter website instead.
Extensions are off in Incognito until you allow them in Manage extensions.
Only the highlighted text is used, so check your selection before you choose a format.
Style guides disagree about small words, so check a headline against the guide you must follow.
The Web Store listing shows version 1.0.0, and features may change in later updates.
Details about the extension come from its Chrome Web Store listing. Everything about how Chrome handles extensions comes from Chrome official pages, listed here. Last reviewed: November 4, 2026.

Short answers to what people ask before they install.
It is a free Chrome extension from Case Converter Tool that changes the case of text you select on a web page. You select the text, right-click and pick a format such as UPPER CASE, Title Case or camelCase. No sign-up is needed.
Yes. The extension is free to install and use, and it does not ask you to create an account or log in.
Install it from the Chrome Web Store, highlight text on any page, right-click the selection and choose a case format from the menu. The steps on this page show each stage in order.
The Web Store listing names UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case and kebab-case. The table on this page shows each one applied to the same phrase.
The listing also names tiny, superscript, mirror and Wingdings text, a paragraph to single line converter, remove text formatting, a Lorem Ipsum generator, a phonetic spelling generator, an HTML to hyperlink converter, a random password generator and five calculators.
It is built to work on any web page, but a few pages draw their own right-click menu and can hide the browser menu. If that happens, copy the text into the Case Converter website instead.
The developer states on the Chrome Web Store listing that text is processed locally and is not stored, tracked or shared, and that no data is collected. This is the developer statement, so read the listing and the privacy policy for yourself before you install.
Chrome shows the permissions an extension requests when you select Add to Chrome, and again in the Details page under Manage extensions. This page explains what common permissions such as contextMenus and clipboardWrite mean so you can judge any prompt.
Select the Extensions icon next to the address bar and choose Pin to keep it visible. To switch it off or remove it, open Manage extensions from the three-dot menu, as Chrome Help describes.
Not by default. Chrome Web Store Help says extensions cannot be added in Incognito, and for an extension you already have, you turn on Allow in incognito in its Details page.
The extension is published on the Chrome Web Store. We have not tested it in other browsers, so we only list Chrome here. If that changes, this page will say so.
Use the extension for quick changes while you work on other pages. Use the Case Converter website when you want to paste a long block, view counts and compare several formats before you copy the result.
