About This Text Case Converter
A text case converter helps you reformat text into different capitalization styles without editing it manually. This is especially useful when you need to reuse the same phrase across multiple contexts – like headlines, button labels, code variables, or URL slugs – and want each version to follow its own casing convention.
Instead of rewriting the same line five different ways, you type it once and instantly generate all the variations you need. This reduces errors, saves time, and keeps your content and codebase clean, consistent, and on-brand across pages, components, and projects.
Feature Explanation – Supported Case Types
- UPPERCASE: Converts every letter to capital letters – great for labels, badges, and emphasis.
- lowercase: Converts everything to lowercase – useful for normalization and technical inputs.
- Title Case: Capitalizes the first letter of each word – ideal for blog titles, headings, and UI labels.
- Sentence case: Capitalizes just the first letter of the sentence while keeping the rest lowercase.
- camelCase: First word is lowercase, following words start with capitals – common for JS variables and functions.
- snake_case: All lowercase with underscores between words – widely used in Python, databases, and config files.
- kebab-case: All lowercase with hyphens – popular for URLs, file names, and CSS class names.
How It Works
- Your input text is read exactly as typed, including spaces and casing.
- The tool splits the content into words using whitespace, then normalizes them (for title, sentence, camel, snake, and kebab case).
- For each case type, a separate transformation function is applied (e.g., uppercasing, lowercasing, capitalizing first letters, or joining words with underscores/hyphens).
- All converted outputs are displayed together in a grid so you can visually compare and choose the one that fits your use case.
- Clicking the copy icon on any block writes that version directly to your clipboard using browser APIs.
How To Use This Text Case Converter
- Paste or type your text into the main input area at the top of the tool.
- Review the automatically generated case variations in the results grid – uppercase, lowercase, title, sentence, camel, snake, and kebab.
- Identify the version that best fits your use case (e.g., camelCase for code, title case for headings).
- Click the copy icon in the top-right corner of that specific block to copy the formatted text.
- Paste it into your document, CMS, design tool, or code editor and repeat as needed.

FAQ – Text Case Converter Tool
1. What is the difference between title case and sentence case?
Title case capitalizes the first letter of each major word, while sentence case capitalizes only the first letter of the sentence and makes the rest lowercase. Sentence case often feels more conversational, while title case is more formal and common in headings.
2. When should I use camelCase, snake_case, or kebab-case?
camelCase is common in JavaScript and many frontend frameworks. snake_case is widely used in Python, databases, and configuration. kebab-case is typically used in URLs, file paths, and CSS class names because it's easy to read and SEO-friendly.
3. Does this tool support multiline text and paragraphs?
Yes. You can paste multiple sentences or full paragraphs. The converter works based on spaces and words, so longer content is also supported without issues.
4. Is my text stored or logged anywhere?
No. The tool runs fully in your browser and does not send your input to any backend. Once you close the page or clear the textarea, your content is gone from the tool.
