How to use this tool
Paste your HTML and minify. Smaller HTML means less data for browsers to download and parse, resulting in faster page rendering.
How It Works
Step-by-step guide to minify html for faster page speed:
- 1
Audit page size
Use browser DevTools to check your current HTML payload size before minifying.
- 2
Paste and minify
Paste your HTML into FixTools and click Minify.
- 3
Compare file sizes
Note the before and after sizes to confirm the reduction.
- 4
Deploy and re-test speed
Deploy the minified HTML and re-run your speed test to measure the improvement.
Real-world examples
Common situations where this approach makes a real difference:
Improving Core Web Vitals for a slow-loading page
A page with a poor LCP (Largest Contentful Paint) score benefits from reducing its HTML size. Minification is the quickest, lowest-risk improvement to try first.
Optimising a mobile landing page
Mobile landing pages need to load fast for paid traffic campaigns. Minifying HTML reduces the initial page payload, improving both load speed and conversion rate.
When to use this guide
Use this when your page performance audit identifies HTML payload size as a contributing factor to slow load times or poor Core Web Vitals scores.
Pro tips
Get better results with these expert suggestions:
Every KB saved counts on mobile
Mobile users on slower connections benefit most from HTML minification. A 20KB saving on a 100KB HTML file is significant on a 3G connection.
Minify HTML along with CSS and JS
For maximum speed improvement, minify HTML, CSS, and JavaScript together. The combined saving is much larger than any single file type alone.
Measure before and after
Use PageSpeed Insights or WebPageTest to measure your page speed before and after HTML minification to quantify the improvement.
