Image Optimization 101: A Beginner's Guide
Image optimization is the process of reducing the file size of your images as much as possible without sacrificing quality, so your page load times remain low. It’s also about image SEO, that is, getting your product images and decorative images to rank on Google and other image search engines.
Why is image optimization important? Faster loading pages lead to better user engagement, higher conversion rates, and improved SEO rankings. In this guide, we'll cover the essential techniques: choosing the right file format (like JPEG, PNG, or WebP), compressing images effectively, and leveraging modern formats for the best results.
Frequently Asked Questions
What is the best image format for websites?
For most photos, WebP offers the best balance of quality and small file size. For graphics with transparency, PNG is still a great choice, although WebP also supports transparency.
How much should I compress my images?
Aim for a quality setting of 75-85 for JPEGs and WebP files. This usually provides a significant size reduction with minimal noticeable loss in quality.
