The Universal Code Formatter and Minifier

Consistently formatted code is the foundation of any maintainable software project. Whether you are inheriting a legacy codebase with mismatched indentation, copying snippets from StackOverflow, or preparing a query for a peer review, messy syntax slows everyone down. Our free online Code Formatter instantly cleans, beautifies, and standardizes your source code across multiple programming languages, ensuring maximum readability with zero configuration required.

Multi-Language Support & Customization

Our formatting engine provides dedicated parsing for JavaScript, TypeScript, HTML, CSS, JSON, and SQL. Unlike basic text aligners, it understands the syntactic structure of each language. For instance, it knows how to properly indent nested HTML tags, align CSS properties, and inject line breaks into complex SQL JOIN statements. You have full control over the output, with options to toggle between spaces and tabs, and define custom indentation sizes (2, 4, or 8 spaces) to match your team's exact style guide.

Instant Code Minification

While formatted code is great for humans, raw byte size matters when deploying to production. With a single click, our tool can reverse the formatting process and minify your code. The minifier aggressively strips out all non-essential whitespace, line breaks, block comments, and inline comments. This is incredibly useful for optimizing small scripts before embedding them directly into HTML documents or reducing payload sizes for API transfers.

Email-Ready Code Snippets

Sharing code via email is notoriously frustrating, as most email clients (like Outlook or Gmail) strip out CSS classes and destroy formatting. Our unique "Email Style" feature solves this by generating a Rich Text HTML block with inline CSS colors. It automatically syntax-highlights your variables, keywords, strings, and comments, embedding the exact colors directly into the HTML tags. You can copy the result straight into your email composer, guaranteeing your code looks beautiful and professional in the recipient's inbox.

Secure, Fast, and Privacy-Focused

Your source code is your intellectual property. We believe you shouldn't have to surrender your proprietary algorithms to a remote server just to fix some indentation. Our Code Formatter operates 100% locally on your machine. The lexical analysis, formatting algorithms, and minification processes execute entirely within the memory of your web browser. Your code is never transmitted, logged, or saved externally.
