Code Minifier & Beautifier
Minify or beautify HTML, CSS, and JavaScript directly in your browser. Use it to shrink snippets before publishing, clean up copied code, or compare original and optimized file size without sending source code to a server.
Key Features
- Minify JavaScript, CSS, and HTML snippets
- Beautify compressed code with readable indentation
- Live before-and-after byte size comparison
- Copy optimized output in one click
- Browser-based processing for pasted code
Common Use Cases
- Compress small HTML, CSS, or JavaScript snippets before embedding them
- Clean minified vendor snippets so you can inspect them during debugging
- Check whether whitespace cleanup meaningfully reduces payload size
- Prepare code examples for docs, tickets, and quick experiments
- Compare readable and compact versions during frontend reviews
Benefits
- No signup, install, or build tool setup required
- Keeps pasted snippets on your device whenever the browser can process them locally
- Useful for quick checks that do not justify a full bundler pipeline
- Pairs well with the HTML, CSS, JSON, and text utilities in XSular Tools
How to use this code minifier
Paste your HTML, CSS, or JavaScript into the input editor, choose the language, then select Minify or Beautify. Click Process to generate the output and review the size comparison below the editors.
Use Minify when you want compact code for a snippet, demo, or inline asset. Use Beautify when pasted code is hard to read and you need indentation before reviewing or editing it.
- Choose JavaScript, CSS, or HTML before processing.
- Use Beautify first when you need to inspect compressed code.
- Use Copy after checking that the output still matches the intended behavior.
What this tool does
The tool removes unnecessary whitespace and comments from CSS and HTML, and uses a JavaScript minifier when the browser library is available. Beautify mode reverses that workflow by adding readable indentation to compact code.
It is designed for practical snippet work, not as a replacement for a production build chain. For full applications, keep using your bundler, source maps, and automated tests.
Who is this tool for?
Frontend developers can quickly test whether a small snippet can be compressed before placing it in a CMS, email template, tag manager, or prototype. Designers and content editors can beautify copied embed code before handing it to a developer.
It also helps students and beginners see the difference between readable source code and compact production-style output.
Common use cases
Use it when a dashboard, CMS field, or documentation page expects a short code snippet and you want to remove extra spacing. It is also handy when a bug report includes minified code that needs to be readable before anyone can review it.
For adjacent workflows, format API data with the JSON Formatter, compare revisions with Text Diff, or generate metadata with the Meta Tags Generator.
