About Text Case Converter

We process text locally for instant feedback. Unicode, accents, and symbols are preserved, while rules for each case style are applied deterministically so the same input always yields the same output. Conversions update as you type with live preview. Whitespace normalization and smart capitalization are available where useful. Developer‑friendly styles (camelCase, snake_case, kebab-case, PascalCase) and writer‑friendly styles (Title Case, Sentence case, UPPERCASE, lowercase) in one place.

💡 Pro Tip

Use kebab-case for URLs and CSS classes, camelCase for JavaScript variables, PascalCase for React components and classes, snake_case for Python and database columns, and Title Case for headlines. This consistency improves code readability and SEO performance.

Frequently Asked Questions

What's the fastest way to convert text to Title Case for headlines?

Paste your text, toggle cleanup if needed, and select Title Case. We handle common small‑word rules and punctuation, producing headline‑ready output you can copy instantly.

How do I keep underscores or dashes when switching between snake_case and kebab‑case?

Convert to the destination style directly. We normalize whitespace first, then map spaces to underscores (snake_case) or dashes (kebab‑case) without altering existing separators unexpectedly.

Can I convert large blocks of Unicode text without breaking characters?

Yes. The converter preserves Unicode, accents, and emoji. Only letter case is modified; symbols and punctuation remain intact unless you choose cleanup options.

When should I use camelCase vs PascalCase in code?

camelCase is typical for variables and functions; PascalCase is used for classes, React components, and types. Convert between them to enforce consistent naming across files.

What's the best way to prepare SEO‑friendly slugs?

Use kebab‑case for clean URLs, then review stop words as needed. Combine with our cleanup to trim extra spaces and normalize quotes before converting.

Does the tool support sentence case for long paragraphs?

Yes. Sentence case capitalizes the first character and lowers the rest, ideal for body text. You can still fine‑tune capitalization for names or acronyms afterward.

How can I quickly copy all versions for documentation?

Use 'Download All' to export every conversion (UPPERCASE, Title Case, camelCase, etc.) into a single text file—useful for style guides and handoffs.

Will formatting like line breaks or indentation be changed?

By default, we minimize whitespace changes. Enable cleanup to normalize spaces and line breaks; disable it to preserve original formatting exactly.

Can I use the tool offline?

Yes for most conversions. The page processes text in your browser, so case changes, cleanup, and copy actions work without a network connection.

What's the difference between Title Case and Sentence case?

Title Case capitalizes principal words (great for headlines). Sentence case capitalizes only the first letter of the sentence—better for readable paragraphs.
