Paste messy HTML, CSS, JavaScript, TypeScript, Python, PHP, Java, JSON, SQL, and more — get clean, readable code in one click. Auto-detect the language, tune indent size, minify when you need to, then copy or download the file. Everything runs locally in your browser.
Important: Web languages use Prettier (with a js-beautify fallback). SQL uses sql-formatter. Python, PHP, Java, and other backends use a local indent engine. Always review output before shipping to production.

Drop in a snippet, open a file, or load a sample. Auto-detect picks the language — or choose it yourself.
Set indent (2 / 4 / tabs) and print width, then format. Minify HTML, CSS, JS, JSON, and XML when you need smaller assets.
Grab the cleaned output instantly, or download it as .html, .css, .js, .py, .php, .java, and more.
A code beautifier (also called a code formatter or prettifier) rewrites source so indentation, spacing, and line breaks follow consistent rules. It does not change what the program does — it changes how humans read it.
This free online code beautifier & formatter runs entirely in your browser. You paste HTML, CSS, JavaScript, Python, PHP, Java, JSON, SQL, and other languages, then download the cleaned file when you are done.
Consistent formatting cuts review time, reduces merge noise, and makes bugs easier to spot. Teams that skip formatting waste hours arguing about style instead of shipping features.
Formatters also help when you inherit minified or one-line dumps from a CMS, email template, or legacy export — beautify first, then edit safely.
Web: HTML, CSS, SCSS, JavaScript, TypeScript, JSX, TSX. Data: JSON, YAML, XML, Markdown. Query: SQL. Backend & systems: Python, PHP, Java, Ruby, Kotlin, Swift, Go, Rust, C, C++, C#.
Auto-detect inspects the snippet and picks a language. Override it anytime from the language menu if detection is wrong.
Beautify expands structure for reading and editing. Minify collapses safe whitespace for smaller HTML, CSS, JavaScript, JSON, and XML payloads — useful before embedding assets or inspecting production bundles.
Do not minify Python, PHP, or Java here expecting a production compressor; those languages need dedicated build tools. Use Beautify for them instead.
Your source never needs to leave the device for formatting. Engines load in the browser and process the text in memory — ideal for client work, private repos, and unfinished drafts.
You can verify with DevTools → Network: formatting does not upload your paste to our servers.
Format before you review. Keep one indent style per project. Commit formatter config (Prettier, EditorConfig) so local editors match this tool. Re-run beautify after generating code from AI so the team sees a consistent style.

Look for multi-language support, local/browser processing, download, and clear minify vs beautify controls. This tool covers HTML, CSS, JS, TS, Python, PHP, Java, JSON, SQL, and more without an account.
No. Formatting runs in your browser. Nothing is sent to our servers to beautify your paste.
HTML, CSS, SCSS, JavaScript, TypeScript, JSX, TSX, JSON, YAML, XML, Markdown, SQL, Python, PHP, Java, Ruby, Kotlin, Swift, Go, Rust, C, C++, and C#.
Yes. Switch to Minify for HTML, CSS, SCSS, JavaScript, TypeScript, JSX, TSX, JSON, and XML. Other languages stay on Beautify.
Click Download after formatting. The file extension matches the detected or selected language (.html, .css, .js, .py, .php, .java, and so on).
Web languages use Prettier-class formatting. Python and brace languages use a local indent engine that is excellent for readability fixes — review complex files before production commits.
Yes. SQL is formatted with keyword casing and standard clause breaks so long queries are easier to read.
Yes. No signup and no API key. Use it as often as you need for development, teaching, and client QA.
