Web Image Optimization Best Practices

Master the art of image optimization. From choosing the right format to automating your workflow, here is everything you need to know to keep your site fast.

Image optimization is more than just compression. It's about delivering the right image, at the right size, in the right format, to the right device.

Responsive Images

Always use the `srcset` attribute to serve different image sizes based on the user's viewport. There's no need to send a 4K image to a mobile phone.

Automated Workflows

Don't manually convert images. Integrate tools like our converter or CI/CD pipelines to automatically process assets. Modern frameworks like Next.js handle this out of the box with the Image component.

Final Thoughts

A consistent optimization strategy is key. Audit your site regularly with Lighthouse to identify new opportunities for improvement.
