Text Tools
Free Online Text Manipulation Tools
Text transformation tasks — counting words, converting capitalization, generating URL slugs — take seconds with the right tools but minutes without them. Every tool here runs entirely in your browser using JavaScript. Your text is processed locally and never sent to a server. Open the browser's Network tab while using any tool and you will see zero outbound requests. Suitable for confidential business documents, draft articles, and proprietary code identifiers.

Tools for Writers and Content Creators
The Word Counter tracks words, characters, sentences, and reading time in real time, using the 238 words-per-minute reading speed from Brysbaert's 2019 meta-analysis (Journal of Memory and Language). It is built for blog posts, essays, social media copy, and academic submissions with strict length requirements. The Text Case Converter transforms text between uppercase, lowercase, title case, sentence case, and more in one click — useful for reformatting quoted text or adjusting heading styles without retyping. The Slug Generator turns any headline into a clean, SEO-friendly URL path using Unicode NFD normalization and hyphen word separation, per Google Search Central guidelines on URL structure.
Tools for Developers
The Text Case Converter handles all programming naming conventions: camelCase (JavaScript, Java), PascalCase (classes, React components), snake_case (Python, SQL), kebab-case (CSS, URLs), and SCREAMING_SNAKE_CASE (constants, environment variables). It detects word boundaries in existing identifiers, so you can convert between conventions without manual splitting. The Slug Generator automates URL-safe identifier creation from human-readable strings, handling accented characters and special symbols via Unicode normalization. The Word Counter's character count is useful for validating input lengths against database VARCHAR constraints and API character limits.
Privacy by Design
Many online text processing tools send your content to a server for processing. Every tool in this collection runs client-side in JavaScript — your text never leaves your device. This is not a policy claim; it is enforced by the architecture. There are no server-side endpoints for these tools, no proxies, and no analytics capturing input values. Suitable for confidential business content, personal documents, and proprietary source code identifiers.
Frequently Asked Questions
Are these text tools free to use?
Yes, all tools are completely free with no usage limits, no account requirements, and no premium tiers. Because all processing happens in your browser, there is no server compute cost — every feature is available to everyone, permanently.
Do the tools store or share my text with anyone?
No. Every tool processes your text entirely within your browser using JavaScript. Nothing is sent to any server, logged to a database, or shared with third parties. Open your browser's Developer Tools Network tab and observe that no outbound requests are made while you type or transform text.
Can I use these tools on mobile phones and tablets?
Yes. All tools are responsive and work on smartphones and tablets as well as desktop browsers. The interface adapts to smaller screens while maintaining full functionality. Performance may be slower on older devices for large text inputs.
Which text tool is best for programming identifier conversion?
Use the Text Case Converter. It supports camelCase, PascalCase, snake_case, kebab-case, and SCREAMING_SNAKE_CASE. It correctly detects word boundaries in existing identifiers, so converting myVariableName to my_variable_name works without manual splitting.
What is the difference between the Slug Generator and the Text Case Converter's kebab-case mode?
The Text Case Converter in kebab-case mode handles simple ASCII text. The Slug Generator also applies Unicode NFD normalization to remove diacritical marks (é → e, ü → u), strips special characters, and collapses consecutive hyphens. For titles with accented characters, symbols, or punctuation, use the Slug Generator. For pure ASCII identifiers, either works.
