A simple extension to convert text case. Transform selected text - uppercase, lowercase, title case and more Transform selected text on any webpage instantly, uppercase, lowercase, title case, sentence case, and toggle case. No copy-pasting to external tools needed. TextCaseConverter is a lightweight Chrome extension that lets you change the case of any text directly on the page you're working on. Select text, click a button, and it's transformed in place. It works in text fields, rich text editors, Google Docs, and even on non-editable page content. Two Modes of Operation - Page Selection Mode Select any text on a webpage, click the TextCaseConverter icon, and pick a transformation. The text is replaced in place — no need to copy, convert elsewhere, and paste back. If the text is non-editable, the transformed result is shown in the popup for easy copying. - Direct Input Mode Paste or type text directly into the extension for quick conversions without needing to interact with any webpage. Ideal for one-off transformations when drafting emails, formatting titles, or cleaning up text. Five Case Transformations - UPPERCASE: Converts all letters to uppercase. Great for headings, acronyms, or emphasis. Example: "sample text" to "SAMPLE TEXT" - lowercase: Converts all letters to lowercase. Useful for cleaning up accidental caps lock or formatting code. Example: "SAMPLE TEXT" to "sample text" - Title Case: Capitalizes the first letter of every word. Perfect for article titles, headings, and proper names. Example: "sample text" to "Sample Text" - Sentence case: Capitalizes only the first letter of each sentence. The standard format for body text and paragraphs. Example: "SAMPLE TEXT" to "Sample text." - tOGGLE cASE: Flips the case of every letter. Uppercase becomes lowercase and vice versa. Handy for fixing text typed with caps lock on. Example: "Sample text" to "sAMPLE TEXT" Works Everywhere - Text inputs and textareas: transformed in place with proper event handling so form frameworks (React, Vue, etc.) pick up the change - Rich text editors (contenteditable): replaces selected text in editors like Gmail compose, Notion, WordPress, and more - Google Docs: copies the transformed text to your clipboard so you can paste it back - Non-editable page text: displays the result in the popup with a one-click copy button Additional Features - Dark & Light Theme: Toggle between dark and light mode with your preference saved across sessions - One-Click Copy: Copy transformed text to your clipboard instantly - In-Place Replacement: No round-tripping to an external converter, text is modified right where you selected it - Auto-Inject: If the content script isn't loaded yet, the extension injects it automatically no page reload needed - Clean, Minimal Interface: No clutter, no ads, no account required Who is this Extension for? - Writers formatting headlines, blog posts, and articles - Developers cleaning up text in documentation or code comments - Students formatting titles for papers and citations - Social media managers formatting post copy - Anyone who's ever typed a whole paragraph with CAPS LOCK ON How to Use - Select text on any webpage (or switch to Direct Input mode) - Click the TextCaseConverter icon in your toolbar - Click the case transformation you want - Done!
