How to Speed Up Your Website
Practical steps to improve website loading speed using free browser-based tools — images, code minification, and more.
Overview
Website speed directly impacts SEO rankings, user experience, and conversion rates. Studies show that a 1-second delay in page load time reduces conversions by 7%. Fortunately, the most impactful performance improvements are also the simplest.
**1. Compress Images (Biggest Win)** Images typically account for 50-80% of a page's total size. Use the Image Compressor to reduce sizes by 50-90% without noticeable quality loss.
**2. Minify CSS, HTML, and JavaScript** Minification removes whitespace and comments from code files, reducing their size by 20-50%. Use the CSS, HTML, and JS Minifiers.
**3. Optimise PDF Files** If your website serves downloadable PDFs, use the PDF Compressor to reduce file sizes, improving download speeds for users.
**4. Reduce Redirect Chains** URLs that redirect multiple times waste loading time. Use proper canonical URLs and minimise redirects.

Frequently Asked Questions
What is LCP and how do I improve it?
LCP (Largest Contentful Paint) measures how long the largest visible element takes to render. Compress the hero image and use WebP format to improve LCP.
How much does CSS minification reduce file size?
Typically 20-40% for CSS. JavaScript minification varies more: 30-60% for typical code.
What is a good PageSpeed score?
Google considers 90+ as "Good". 50-89 is "Needs improvement". Below 50 is "Poor". Image compression and minification alone can often move a site from 50 to 85+.
Does image compression affect image quality?
At 75-85% quality, the difference is imperceptible on screens. The Image Compressor provides a side-by-side comparison so you can judge for yourself.
