A fast, accessible website wins more visitors and more enquiries. These free tools help with the quick wins that make the biggest difference, starting with images, the heaviest part of most web pages.
Why speed matters
Visitors expect pages to load quickly, especially on phones. Slow pages lose people before they read a word, and Google measures real-world loading and responsiveness through its Core Web Vitals. One of these, Largest Contentful Paint, is often held back by a single large image at the top of the page. Making images smaller is usually the fastest improvement a website owner can make without a developer.
Quick wins for a faster website
- Compress and resize images before uploading them.
- Use modern formats such as WebP for photos.
- Set image dimensions so the layout does not jump while loading.
- Lazy-load images further down the page, but load the main image straight away.
- Limit plugins, scripts and fonts to the ones you really need.
- Use caching through your host or a caching plugin.
Which tool to use
The Image Compressor & WebP Converter shrinks JPG, PNG, WebP and GIF images and converts them to WebP, JPEG or PNG, with a quality slider and resize presets. It processes up to 20 images at a time entirely in your browser, so private photos never leave your device.
Measuring the result
Test your important pages before and after with Google’s PageSpeed Insights, and check the Core Web Vitals report in Search Console over the following weeks. Real-user data takes time to update, so give it about a month before judging the full effect.
Tips for local businesses
Most local searches happen on phones, often on mobile data, so speed matters even more for local businesses. Compress the photos on your homepage, service pages and gallery first, as they are usually the largest files. Use real photos of your team, premises and work rather than stock images, and give them descriptive file names and alt text. Compress the photos you upload to your Google Business Profile as well.
Frequently asked questions
What image size should I upload?
About twice the width the image is displayed at, for sharp results on high-resolution screens. For most content images that means 1200–1600 pixels wide.
Is WebP safe to use?
Yes. All current versions of the major browsers support it.
Will compression make my images look worse?
At sensible quality settings (around 75–85%), most people cannot see a difference on screen, while the file becomes much smaller.
