HTML Code Minifier

Tool Introduction

The HTML Code Minifier is an efficient online utility designed for developers and website administrators to optimize and streamline HTML files. By intelligently removing unnecessary whitespace, line breaks, comments, and empty attributes, and integrating deep compression features for CSS, JavaScript, and SVG, this tool can significantly reduce the size of HTML files, thereby improving website loading speed and user experience. It not only helps you streamline your code but also enhances your website's SEO performance to some extent.

How to Use

1. Paste the HTML code you need to minify into the "Before Compression" input box on the left.
2. According to your needs, select or deselect various compression options below, such as "Remove Whitespace", "Remove Comments", "Minify CSS", "Minify JS", etc.
3. If you have specific JavaScript code length restrictions, you can set them in the "Max Length of Minified JS Code" input box.
4. After confirming all settings, the tool will automatically perform compression and display the minified HTML code in the "After Compression" output box on the right.
5. You can directly copy the code from the "After Compression" area for your project.

Input Parameter Format:

• "Before Compression": Accepts any valid HTML code string.
• Checkbox options: Used to control the compression strategy, with recommended compression settings as default.
• "Max Length of Minified JS Code": Accepts a numeric string, representing the maximum length limit.

Output Result Format:

• "After Compression": Outputs a W3C-compliant minified HTML code string.

Frequently Asked Questions

• Q: What input formats does this HTML minification tool support?
• A: This tool primarily supports standard HTML code as input. Please ensure that your input is a valid HTML structure.
• Q: Will the minified code affect the display or functionality of the webpage?
• A: Under default recommended settings, minification typically does not affect the display and functionality of the webpage. However, if aggressive options like "Remove Inline JS/CSS" are enabled, it might alter original functionality, so it's recommended to verify in a testing environment.
• Q: How should I choose compression options?
• A: For most scenarios, keeping the default options (remove whitespace, comments, minify CSS/JS/SVG) achieves the best compression effect and compatibility. If you have special requirements for your code, such as needing to preserve certain line breaks or inline styles, you can adjust as needed.
• Q: What does "Minify SVG" mean?
• A: This means the tool will attempt to optimize SVG code embedded in HTML, removing unnecessary tags and whitespace to further reduce file size.

Important Considerations

• Input Data Validity: Please ensure that your input HTML code is complete and syntactically correct; otherwise, the compression result may not meet expectations.
• Option Selection Caution: The "Remove Inline JS/CSS" option will remove all <style> tag content and <script> tag content in HTML, as well as the style attribute on elements. Please use with caution after clearly understanding its impact, to avoid disrupting page layout or functionality.
• Test First: It is strongly recommended to perform comprehensive functional and compatibility testing in a development or testing environment before deploying the minified HTML code to a production environment, to ensure normal website performance.
• Special Characters: By default, the tool performs encoded entity conversion. If your HTML contains many special characters and you wish to retain their original entity form, please consider unchecking the "Enable HTML Escaping" option.
