How to optimize your images

By now it is no secret that image optimization is vital for every successful website, so let’s take a look at how we can optimize your images for your website.

  • Choose the right format
  • Use a CDN
  • Use compressed images

Which image formats shall I use?

JPG: Also known as JPEG, best for Photographic images, (Headshots, Product Photos). Be careful not to compress them too high, otherwise, the photo gets unclear and pixels. The key is to use small file formats, this improves page load time

PNG: Best used for graphic images with intricate design for texts, line drawings/arts, icon graphics, and small images on transparent background. Keep in mind PNG is larger than JPG, PNG-24 has a wider color palette than PNG-8 (only 256 colors)

SVG: Best used for logos, line graphics/images, animated web design elements. Key characteristics of this format is the vector-based format (compared to JPG and PNG which are pixel-based), not as versatile as JPG and PNG, can scale up without losing sharpness, ideal for mobile devices, small file size

GIF: Best used for small animated graphics, or small video clips. It’s limited to 256 colors, often used in social media and marketing. It is not recommended for images

Bonus

WEBP: Best to use for large images and photos. WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Keep in mind that older browsers do not support the new format generated by Google.

Tools for compressing Images

ImageResizer.com: is a free tool that can ideally be used for personal or small website owners who need to optimize view images.

TinyPNG: offers a free basic version and paid service.Ideal for website owners who need high-quality typical PNG images.

Kraken.io: a paid service for larger websites with lots of images, that demands more bandwidth and storage.

Also in WordPress, you can find various plug-ins like Imagify, ShortPixel or WP Smush for website image optimization.

SEO Website Image Optimization

Making images more readable for search engines helps in your SEO page score. User optimized image file names, image titles, include ALT text, make use of sitemaps and use responsive images.

I hope you like this small guide as much as I do and it helps you in your mission for Website Image Optimization for a speedy user experience.
