Heavy images are the most common cause of slow websites. Optimisation includes compression, modern formats (e.g. WebP) and the right sizes for each device.
What it means in practice
Image optimisation means preparing photos and graphics so they look good but weigh as little as possible: compression, modern formats (WebP, AVIF), the right dimensions for different screens and deferred loading of images below the fold.
Why it matters for your business
Heavy images are the most common cause of slow websites, especially on phones with mobile data. A slow site means worse Google rankings and more people leaving before they see your offer.
Examples and good practice
- Don’t upload photos straight from the camera (often 5–10 MB).
- Use WebP or AVIF.
- Match the size to where the image is displayed.
- Use lazy loading for images further down the page.
How Novi handles it
On Novi websites images are automatically compressed, saved in modern formats and lazy-loaded where it makes sense. You just upload the photo.
