Frequently Asked Questions
What is an HTML/CSS/JS Filter tool?
An HTML/CSS/JS Filter tool is a web development utility that extracts, separates, minifies, and beautifies HTML, CSS, and JavaScript code from mixed sources. It helps developers organize code, optimize for production, and improve readability by processing inline styles and scripts into separate, manageable files.
How do I separate CSS and JavaScript from HTML files?
Simply paste your HTML code containing inline CSS and JavaScript into the input area, select 'Extract' mode, and click 'Process Code'. The tool automatically identifies and separates CSS from <style> tags and JavaScript from <script> tags, providing clean, organized output files for each code type.
Can I minify and beautify code simultaneously?
You can switch between different processing modes - Extract, Minify, or Beautify - to get the desired output format. While you cannot apply multiple modes simultaneously, you can process your code multiple times with different modes to achieve the exact formatting you need for your development workflow.
Is the HTML/CSS/JS Filter tool free to use?
Yes, this tool is completely free to use with no limitations on file size or processing frequency. You can process unlimited amounts of code, download results in various formats, and use all features without any cost, registration requirements, or hidden fees.
Is my code secure when using this filter tool?
Yes, your code is completely secure. All processing happens locally in your browser using client-side JavaScript. Your code is never uploaded to external servers, transmitted over the internet, or stored anywhere, ensuring complete privacy and security of your source code and intellectual property.
What file formats can I download?
You can download the processed code in appropriate formats - .html for HTML content, .css for stylesheets, and .js for JavaScript files. The tool automatically suggests the correct file extension based on the selected output type and content, making it easy to integrate into your development workflow.
Does the tool support advanced minification options?
The tool provides comprehensive minification that removes unnecessary whitespace, comments, and optimizes code structure for production use. It handles inline CSS within HTML, JavaScript optimization, and maintains code functionality while significantly reducing file sizes for improved website performance.
Can I process email templates and CMS-generated code?
Absolutely! The tool excels at processing email templates, CMS-generated HTML, WordPress themes, and other complex HTML documents with mixed inline styles and scripts. It's particularly useful for cleaning up automatically generated code and organizing it into maintainable, separate files.
