Essential Image Optimization
Per Tammy Everts, adding images to a page or making existing images larger have been proven to increase conversion rates. It’s unlikely that images will go away and so investing in an efficient compression strategy to minimize bloat becomes important.
Image optimization should be automated. It’s easy to forget, best practices change, and content that doesn’t go through a build pipeline can easily slip. Most CDNs (e.g. Akamai) and third-party solutions like Cloudinary, imgix, Fastly’s Image Optimizer, Instart Logic’s SmartVision or ImageOptim API offer comprehensive automated image optimization solutions. Image optimization consists of different measures that can reduce the file size of your images. It ultimately depends on what visual fidelity your images require.
The smaller in file-size you can make your images, the better a network experience you can offer your users – especially on mobile. In this online ebook, we’ll look at ways to reduce image size through modern compression techniques with minimal impact to quality.
