HTML Minifier

Compress HTML by stripping comments, collapsing whitespace, and removing optional quotes. See compression statistics. Free, instant, 100% private.

Only safe when attribute values contain no spaces, quotes, or special characters.

About HTML Minification

HTML minification reduces page weight by removing unnecessary characters without affecting rendering:

  • Comment removal: Strips HTML comments (<!-- -->) from the markup
  • Whitespace collapse: Removes redundant spaces and newlines between tags
  • Attribute quote removal: Optionally removes quotes from attribute values where HTML spec allows it
  • Content preservation: Whitespace inside <pre>, <code>, <textarea>, <script>, and <style> is preserved

All processing happens in your browser. Your HTML never leaves your device.

📋 Common Use Cases

Production Deployment

Minify CSS, JavaScript, and HTML files before deploying to production. Smaller files load faster and consume less bandwidth for users.

Build Pipeline Integration

Quickly minify individual files during development to test production behavior. Verify that minification doesn't break functionality.

Performance Optimization

Reduce total page weight by minifying inline styles and scripts. Combine with compression for maximum size reduction.

Code Size Analysis

Compare original vs minified file sizes. Identify which files benefit most from minification and track optimization progress.

🪜 How to Use This Tool

  1. Paste your source code
    Enter CSS, JavaScript, or HTML into the input area. Most minifiers accept raw code or file uploads.
  2. Configure minification level
    Choose aggressive or safe minification. Some tools let you preserve specific comments, license headers, or debug information.
  3. Review minified output
    See the compressed code and size reduction statistics — original size, minified size, and percentage saved.
  4. Copy or download
    Copy minified code to replace your source in production, or download as a .min file to serve alongside your original.

Frequently Asked Questions

Are these dev tools free?▼

Is my data sent to a server?▼
No. Base64 encoding, URL encoding, JWT decoding, hash generation, and regex testing all happen in your browser. Your tokens and secrets stay on your device.
Can I decode JWTs safely?▼
Yes. JWT decoding happens entirely in your browser. The token never leaves your device. Only the header and payload are decoded — signatures are not verified server-side.
