## What is Case Converter?

Case Converter is a free online text tool from Farvixo that lets you UPPER, lower, Title, camelCase, snake_case & more. It updates as you type and runs entirely in your browser, so the text is never transmitted. There is no length limit imposed by a server, no account and no cost — use it as often as you need.

## How to use Case Converter

1. **Paste your text** — Paste or type into Case Converter. Nothing is sent anywhere — the text stays in your browser.
2. **Choose how to transform it** — Pick the options you want. Case Converter updates the output as you type, so you can see the effect immediately.
3. **Copy or download** — Take the result to your clipboard or save it as a file. Unlimited use, no account needed.

## Use cases

- Writers and students checking length against a word or character limit
- Cleaning up text pasted out of a PDF, email or spreadsheet
- Reformatting a list or block of copy before publishing it
- Comparing two drafts to see exactly what changed

## Tips

- Text pasted from Word or a PDF often carries invisible characters; clean it before counting or comparing.
- Character counts differ between platforms — some count emoji as one character, others as two.
- The result updates live, so you can adjust the input and watch the output rather than re-running the tool.

## Common problems

- **The count does not match another tool** — Tools differ on whether line breaks, trailing spaces and emoji count. Check which rule the platform you are targeting applies.
- **Formatting was lost on paste** — This is a plain-text tool by design. Apply formatting after transforming the text in your editor.
- **Strange symbols appear in the output** — The source contained smart quotes, non-breaking spaces or zero-width characters. Strip them first, then re-run.

## FAQ

### What is the difference between Title Case and Sentence case?

Title Case capitalises the significant words — "How to Convert a PDF". Sentence case capitalises only the first word and proper nouns — "How to convert a PDF". Publications differ on which small words to capitalise, so follow whichever style guide you are writing to.

### Which case should I use for code?

Follow the language convention rather than personal preference: camelCase for JavaScript and Java variables, snake_case for Python and SQL, kebab-case for CSS classes and URLs, PascalCase for classes and React components.

### Why should URLs use kebab-case?

URLs are case-sensitive on most servers, and underscores are visually lost when a link is underlined. Lowercase words separated by hyphens avoid both problems, and search engines treat hyphens as word separators.

### Is my text uploaded?

No. Conversion happens as you type, in your browser, with no length limit and nothing transmitted.

### Does it handle non-English text?

Yes. Case conversion follows Unicode rules, so accented Latin, Greek and Cyrillic convert correctly. Scripts without letter case, such as Devanagari and Bengali, are left unchanged.
