HTML Code Compression

Tool Introduction

The HTML Code Compression tool 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 functions 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 code but also enhances website SEO performance to some extent.

How to Use

1. Paste the HTML code you need to compress 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", "Compress styles", "Compress JS", etc.
3. If you have specific JavaScript code length restrictions, you can set them in the "Maximum length of compressed JS code" input box.
4. After confirming all settings, the tool will automatically compress and display the streamlined 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.
• Various checkbox options: Used to control the compression strategy, with recommended compression settings as default.
• "Maximum length of compressed JS code": Accepts a numeric string, representing the maximum length limit.

Output result format:

• "After compression": Outputs a streamlined HTML code string that complies with W3C standards.

Frequently Asked Questions

• Q: What input formats does this HTML compression 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 compressed code affect the display or functionality of the webpage?
• A: Under the default recommended settings, compression usually does not affect the display and functionality of the webpage. However, if aggressive options such as "Remove inline JS/CSS" are enabled, it may change the original functionality. It is recommended to verify in a test environment.
• Q: How should I choose compression options?
• A: For most scenarios, keeping the default options (remove whitespace, comments, compress CSS/JS/SVG) can achieve the best compression effect and compatibility. If you have special requirements for the code, such as needing to retain certain line breaks or inline styles, you can adjust as needed.
• Q: What does "Compress 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.

Notes

• Input data validity: Please ensure that the HTML code you enter is complete and syntactically correct, otherwise the compression result may not meet expectations.
• Careful option selection: 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 tests in a development or test environment before deploying the compressed HTML code to a production environment, to ensure the website performs normally.
• Special characters: By default, the tool performs encoded entity conversion. If your HTML contains a large number of special characters and you wish to retain their original entity form, please consider unchecking the "Enable HTML escaping" option.
