Format & Beautify Code
Beautify minified HTML, CSS, and JavaScript for readability. Preview markdown rendered in real time. Essential for debugging templates, learning from minified sources, and preparing documentation.
Convert & Encode Text
Transform text between different encodings and formats. Convert text case for code conventions, encode/decode Base64 for data transmission, percent-encode URLs, and escape HTML entities for safe rendering.
Generate Content
Generate placeholder text, SEO-friendly URL slugs, formatted ASCII tables for documentation, and build URLs with query parameters. Perfect for designers, content creators, and documentarians.
Analyze Text
Count words, characters, sentences, and reading time. Sort, deduplicate, and clean text lines. Parse and identify browser, OS, and device from user-agent strings for analytics and debugging.
Compare & Test
Find differences between two texts with line-by-line highlighting. Test regular expressions with real-time matching, group capture, and replacement previews. Ideal for code review and pattern debugging.
URL Tools
Encode and decode URLs, parse query strings into key-value tables, and build URLs with visual parameter controls. Essential for API debugging, link generation, and request inspection.
Related Tools — Use Them Together
These tools are designed to work together in real-world workflows. A typical text processing pipeline might involve generating content with lorem ipsum, converting it to a specific case, counting the words to hit a target length, and then encoding special characters for a URL. Or: format your HTML, extract the text content into a word counter, compare revisions with the diff checker, and generate a slug from the final title.

Why Use Text Tools Online?
Text manipulation is a fundamental part of web development, content creation, and data processing. Every day, developers need to format HTML for readability, generate SEO-friendly URL slugs, analyze word count for content optimization, compare document versions, encode data for safe transmission, or test regular expressions against sample input. Having a comprehensive set of string manipulation tools at your fingertips turns these routine tasks from manual effort into one-click operations.
Online text formatters save significant time when working with minified code. When you inspect network responses or third-party scripts, the HTML, CSS, and JavaScript often arrive as single-line blobs. A code beautifier tool instantly indents and organizes that code into readable, debuggable structure. Similarly, text case converter tools eliminate tedious retyping when you need to transform camelCase variable names to snake_case for a database migration or to kebab-case for a URL parameter.
All our text processing tools run entirely in your browser using client-side JavaScript. Your text data is never uploaded to a server, stored in a database, or transmitted over the network. This privacy-first approach means you can confidently use a URL encoder, Base64 encoder, or text diff tool with sensitive content like API keys, internal documents, or personal data without any security concerns.
Best Practices for Text Processing
Validate Before Publishing
Always run HTML and CSS through a formatter before deploying. Minified code can hide subtle syntax errors that cause rendering issues across browsers.
Optimize Content Length
Use word counter and text tools to hit target lengths for blog posts, meta descriptions, and social media content. Most search engines truncate meta descriptions at 160 characters.
Use Consistent Case Conventions
Standardize on camelCase for JavaScript, snake_case for database columns, and kebab-case for URL slugs. Use our text case converter online tools for instant transformation.
Encode URLs Properly
Always encode special characters in URLs to prevent broken links and security vulnerabilities. Use our URL encoder for query parameters with spaces or symbols.

Frequently Asked Questions
Are these text tools free?
Yes, all text utilities for developers are completely free with no usage limits or sign-up required.
Is my text data safe?
Yes. All processing happens locally in your browser. Your data never reaches any server.
What types of text can I process?
Our string manipulation tools work with plain text, HTML, CSS, JavaScript, markdown, URLs, Base64, and regex patterns. Most tools accept direct text input for quick processing.
Can I format minified code?
Yes. Use the HTML Formatter, CSS Formatter, or JavaScript Formatter to beautify minified code with configurable indentation and sorting.
