HTML Compressor: Minify HTML and Measure Gzip Size
HTML Compressor minifies pasted HTML using the same minification as the HTML Minifier, then measures the result’s actual gzip size with the browser’s native CompressionStream. It reports original, minified, and gzipped byte counts so you can compare the markup before and after minification and see the compressed size a CDN or web server would send. Choose the available minification options before copying the compact result.
HTML Compressor is an in-browser HTML minification and gzip size tool for developers who want to compare compact markup with its compressed size. It applies the same minification as the HTML Minifier, then uses the browser’s native CompressionStream to measure the resulting HTML’s actual gzip size. The tool displays original, minified, and gzipped byte counts.
To use the HTML Compressor, paste or drop HTML, choose the minification options, and review the compact result and measurements. The minification stage follows the same behavior as the HTML Minifier, and the gzip measurement is applied to that minified result. Comparing the three byte counts helps show the difference between minification and gzip compression.
HTML is a markup format for structuring content, while gzip is a compression format used to reduce data size for transfer. Minifying HTML can make the markup more compact without changing what it means; measuring its gzip size shows the compressed size a CDN or web server would send. These figures help developers assess both the minified output and its compressed transfer size.
Processing runs entirely in your browser: your HTML is processed on your device and is not uploaded, stored, or sent to a server. Once the page has loaded, the tool works offline because it has no server dependency.
HTML Compressor is useful for developers and DevOps engineers who want to inspect HTML size, prepare a compact payload, or compare minification results with gzip measurements. The byte counts provide a straightforward way to review the effect of minifying before using the output.
Step 1: Paste or drop your HTML into the tool. It accepts HTML input and processes it in your browser.
Step 2: Choose the minification options. The tool applies the same minification as the HTML Minifier.
Step 3: Review the compact HTML and compare the original, minified, and gzipped byte counts. The gzip measurement is taken from the minified result.
Step 4: Copy the compact result for use in your project, URL, header, or config value.
Use case: Shrink HTML for shipping while keeping its meaning unchanged. Compare the original and minified byte counts to see the difference.
Use case: Decide whether minifying is worthwhile by checking the size before and after minification, along with the resulting gzip size.
Use case: Prepare compact HTML for a URL, header, or config value when a smaller payload is useful.
Use case: Estimate the compressed size a CDN or web server would send by reviewing the actual gzip measurement.
Use case: Check the impact of your chosen minification options by comparing the reported byte counts for the result.
Use case: Review original, minified, and gzipped sizes together when evaluating HTML payloads during development.
