If you are a UK small business owner thinking about compress images for website speed, this guide explains the practical website decisions that matter before you spend time or money. The aim is to help you understand the issue clearly, use the right free tools where they help, and know when a professional website build is the better route.
Why large images slow websites down
Images often make up most of the weight on a small business website. A beautiful hero image can become a problem if it is several megabytes and loaded on mobile. The visitor sees delay before they see value.
What image compression does
Image compression reduces file size while keeping the image visually acceptable. For website use, the aim is not print-level perfection; it is a sharp-looking image that loads quickly on real devices.
Why WebP can help
WebP is designed for the web and can often create smaller files than JPG or PNG at similar visual quality. It is especially useful for hero images, service photos, gallery images, and blog graphics.

How to check if your images are too large
Use an image size checker before uploading images to your website. As a rough rule, most content images should be far below 500 KB, and many can sit under 200 KB after compression.
When to redesign or optimise your website properly
Compression helps, but it will not fix every performance issue. If your website still feels slow after image optimisation, the problem may be layout, scripts, hosting, caching, or the build itself.

Does compressing images reduce quality?
It can, but sensible compression keeps images looking good while making files much smaller for the web.
Should I use WebP for my website?
For most modern websites, WebP is a strong choice for photos and graphics because it keeps file sizes lower.
Are the dean-da-dev image tools private?
Yes. The image tools process files in your browser, so files are not uploaded to a server.
