Code Compressor
Strip unnecessary characters and whitespace from source files so they load faster in browsers or run more efficiently in other environments. This is a simple way to optimize delivery without changing behavior.
Code Compressor
Compress and minify your source code to enhance performance and reduce file size. Supports JavaScript, TypeScript, CSS, HTML, JSON, and many more languages.

Boost Page Performance
Minification strips all whitespace, comments, and redundant characters from your JavaScript, CSS, and HTML, dramatically reducing file size: often by 40–80%. Smaller files mean faster downloads, lower bandwidth costs, and higher Lighthouse scores.
Format, Unminify & Beautify
Transform a single-line minified bundle back into perfectly indented, human-readable code in one click. Ideal for auditing third-party scripts, debugging build output, or understanding open-source libraries without a source map. Supports JS, TS, CSS, HTML, JSON, and more.
Secure, Private Processing
All compression and decompression runs entirely in your browser session. Your source code is never transmitted to or stored on our servers: making this tool safe for proprietary code, internal configs, and production secrets.
How to Minify or Beautify Code in 4 Steps
Choose your mode
Select Compress / Minify to strip whitespace and shrink file size for production, or switch to Decompress / Beautify to convert a minified bundle back into clean, readable, indented code.
Paste your source code
Copy any raw, formatted, or minified code into the left input panel. The engine auto-detects the programming language: JavaScript, TypeScript, CSS, HTML, JSON, Python, Java, and more are all supported.
Click the action button
Hit Compress Code or Beautify Code. Compression completes in milliseconds, removing comments, whitespace, and shortening variable names where possible. Beautification applies standard indentation and line-break rules instantly.
Copy or unlock to edit
Grab the processed output with one click using the Copy button. Or toggle Unlock on the output panel to make manual edits: adjust imports, tweak formatting, or strip a specific section: before copying the final result.
Who Uses the Code Compressor?
Frontend Developers
Minify JavaScript bundles, CSS stylesheets, and HTML templates before pushing to production. Cut load times, reduce bandwidth costs, and hit Core Web Vitals targets without configuring Webpack or Rollup.
Debugging Developers
Unminify and beautify third-party libraries, CDN scripts, or CI build output to trace bugs and understand logic without needing source maps or the original repository.
Engineering Teams
Normalize code formatting before pull requests and code reviews. Run a quick beautify pass to enforce consistent indentation style across contributions from different IDEs and OS environments.
Students & Learners
Decompress minified examples from tutorials, CodePen snippets, or popular open-source libraries to read and study the logic in a properly formatted, approachable structure.
DevOps & Build Engineers
Quick-compress JSON config files, shell scripts, and infrastructure-as-code snippets before embedding them in CI/CD pipelines or environment variables with strict size limits.
Performance Engineers
Audit file-size savings across multiple code snippets before committing to a bundler integration. Compare raw vs. minified byte counts to prioritise which assets to optimise first.
Endless Forge vs Local Build Tools
Instant dual-mode minification and beautification in your browser: no Webpack, no Gulp, no Terser config, no install.
