Code Minifier & Beautifier

Minify or beautify CSS, JavaScript, and HTML — safely, entirely in your browser. Comments and unnecessary whitespace only; nothing renamed or restructured.

Code Minifier and Beautifier Tool

Minify or Beautify Code

How to Use This Tool

  1. Choose a language: CSS, JavaScript, or HTML.
  2. Choose Minify (to shrink the code) or Beautify (to reformat it readably).
  3. Paste your code into the input box and click the action button.
  4. Copy the result, or switch languages/actions and run it again.

What "Safe Minification" Means Here

This tool removes comments and unnecessary whitespace — extra blank lines, and (for CSS and HTML) spacing around punctuation like braces and colons. It deliberately does not rename variables, join separate lines together, or otherwise restructure your code the way an aggressive production build tool might. That trade-off is intentional: it keeps the result predictable and safe to review, even though it won't shrink the file quite as much as a full build-tool minifier would.

Why Minify Code?

  • Smaller file size: less data for a browser to download, which helps pages load faster.
  • Quick sharing: pasting a compact snippet into a chat, ticket, or config file without extra formatting getting in the way.
  • Embedding: inlining CSS or JS directly into HTML without unnecessary bulk.

Frequently Asked Questions

What does "minify" actually remove?

Comments and unnecessary whitespace (extra blank lines, and — for CSS/HTML — spacing around punctuation). It deliberately does not rename variables, join lines together, or restructure your code, which keeps the transformation safe and predictable rather than maximally small.

Is this safe to use on real production code?

For CSS and HTML, yes, for the vast majority of everyday code — comments and quoted strings are protected before anything is stripped, so their contents are never touched. For JavaScript specifically, this uses a heuristic (not a full parser) to tell a division operator apart from a regex literal, which very rarely can misjudge unusual code. Always review the minified output, and keep your original source as the version you actually edit.

Why doesn't Beautify produce "properly" formatted code like a full formatter would?

Beautify here is a simple, indentation-based reformatter — it adds newlines and indentation around braces and semicolons/tags, but it isn't a full parser and won't make the same judgment calls a tool like Prettier would on complex code. It's meant for a quick, readable pass over minified or poorly formatted code, not as a replacement for a project's real formatter/linter.

Will minifying break my code?

It shouldn't, for the reasons above — but as with any minifier, test the result before relying on it. If something looks wrong, compare it against your original, which this tool never modifies in place.

Does this handle CSS/JS/HTML comments correctly?

Yes — comments are detected properly even when they appear next to strings or other code, and their content (along with the content of quoted strings) is never altered by minification.

What about content inside <script>, <style>, <pre>, or <textarea> tags when minifying HTML?

Those blocks are protected before any whitespace collapsing happens, since whitespace inside them can be meaningful (e.g. inside <pre>) or syntactically significant (inside <script>/<style>). Script and style blocks are still minified using this tool's own CSS/JS logic; pre and textarea content is left completely untouched.

Is my code sent anywhere?

No. Every transformation runs locally in your browser using JavaScript. Nothing you paste here is sent to Brekzy or stored anywhere.

Is this tool free to use?

Yes, completely free, with no account, sign-up, or usage limit.
