About Case Converter
Case Converter changes the letter case of any text you paste, so you never have to retype a sentence just to fix its capitalization. Switch text to UPPERCASE, force everything to lowercase, or turn a block of shouting caps into readable lowercase in a single click. It also handles the two cases people mix up most: Title Case, which capitalizes each major word for headlines and titles, and Sentence case, which capitalizes only the first letter of each sentence like normal prose.
Beyond everyday capitalization, it converts the same text into programmer-friendly formats: camelCase (myVariableName), snake_case (my_variable_name), and kebab-case (my-variable-name). Paste your text, pick a mode from the dropdown, and the result updates instantly, along with a live character, word, and line count so you can check length while you work. A one-click Copy button drops the converted text onto your clipboard, ready to paste into a document, code editor, spreadsheet, or CMS.
This is a plain online text case converter with no sign-up, no usage limits, and no watermarks, so you can run as much text through it as you like. Everything happens locally in your browser using JavaScript, which means your text is never uploaded to a server or stored anywhere, and the tool keeps working offline once the page has loaded.
Frequently asked questions
- Is the Case Converter free to use?
- Yes, it is completely free with no sign-up, no usage limits, and no watermarks. You can convert as much text as you want, as often as you like.
- How do I convert uppercase to lowercase?
- Paste your text and choose the lowercase mode from the dropdown. Every letter, including a full block of ALL CAPS, is instantly turned to lowercase, then you can copy the result with one click.
- How do I make all my text UPPERCASE?
- Select the UPPERCASE mode after pasting your text and every letter is capitalized at once. It is handy for headings, labels, or emphasizing a short phrase without holding down the shift key.
- How do I change text to all lowercase?
- Pick the lowercase option and the tool strips out every capital letter, leaving clean lowercase text. This is useful for tidying up messy pasted content or normalizing tags, usernames, and file names.
- What is a Title Case converter used for?
- Title Case capitalizes the first letter of each major word while keeping small words like 'and', 'of', or 'the' lowercase, which is the standard style for headlines, article titles, and book titles. Choose the Title Case mode and your text is formatted that way automatically.
- What is the difference between Title Case and Sentence case?
- Title Case capitalizes the first letter of each major word, which is common for headlines. Sentence case only capitalizes the first letter of each sentence, like normal prose, leaving the rest of the words lowercase.
- What is capital case, cap case, or caps case?
- Those names usually refer to capitalizing the first letter of every word, which is what the Title Case mode does here. If instead you mean turning text into full capital letters, use the UPPERCASE mode.
- What case styles can I convert to?
- Seven styles: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, and kebab-case. Just choose one from the dropdown and the result updates instantly.
- How do camelCase, snake_case, and kebab-case work?
- These programmer-friendly formats split your text into words on spaces, punctuation, and capital-letter boundaries, then rejoin them. camelCase joins words with no spaces and capitalizes each after the first (myVariableName), snake_case joins with underscores (my_variable_name), and kebab-case joins with hyphens (my-variable-name).
- Can I copy the converted text easily?
- Yes. Click the Copy result button and the converted text is placed on your clipboard, ready to paste anywhere. The tool also shows live character, word, and line counts as you type.
- Do I need to download anything, or does it work online?
- It is a fully online text case converter that runs right in your browser, so there is nothing to install. Once the page has loaded it also keeps working offline, so you can convert text even without a connection.
- Is my text uploaded or stored anywhere?
- No. All conversion happens locally in your browser using JavaScript. Your text never leaves your device, is never sent to a server, and is not saved anywhere. Once the page loads it even works offline.
