The Best Guide to Compressing HTML Files to ZIP
Introduction
Compressing HTML files is a wise step to reduce their size, thereby improving Page loading speed. Compression reduces file size by removing unnecessary spaces, indents, and comments.
Method
There are several ways to compress HTML files into ZIP:
1. Use online tools:
- FileOptimizer: https://fileoptimizer.com
- TinyPNG: https://tinypng.com
With these tools, you can upload your HTML files and automatically compressed.
2. Use the command line tool:
- gzip:
gzip -c yourfile.html > yourfile.html.gz - 7-zip:
7z a -tzip yourfile.html.zip yourfile.html
These command line tools will create a .gz or .zip after compression document.
3. Using Node.js script:
const fs = require('fs');
const zlib = require('zlib');
fs.readFile('yourfile.html', (err, data) => {
if (err) throw err;
zlib.gzip(data, (err, compressedData) => {
if (err) throw err;
fs.writeFile('yourfile.html.gz', compressedData, (err) => {
if (err) throw err;
console.log('File compressed successfully.');
});
});
});This script uses the zlib module to compress HTML files to GZIP.
Practical case

<html> <head> <title>My Page</title> </head> <body> <h1 id="Hello-world">Hello, world!</h1> </body> </html>
After using the online tool FileOptimizer to compress, we get a volume of only It is a 564B ZIP file. Without compression, the file size is 974 Bytes.
