How To Efficiently Encode Images On WordPress

Images are key for engaging visitors and sharing information. But if they’re not optimized properly, they can bog down your website.

This guide will show you how to encode images efficiently on WordPress and suggest tools to make it easier.

Why efficient image encoding matters

Every byte counts when it comes to website speed.

One key recommendation from Pagespeed Insights is to efficiently encode images, an important step in optimizing your site for faster loading times and improved user experience.

Large, uncompressed images can significantly increase page load times, leading to higher bounce rates and lower search engine rankings.

By efficiently encoding images, you can reduce file sizes without sacrificing quality, resulting in faster loading times and better overall performance.

How to efficiently encode images on WordPress

Two efficient methods exist for encoding images and addressing this PageSpeed Insight suggestion — specifically compressing the images and serving them in next-gen formats.

However, we’ll cover three other additional steps that are available in optimizing the images.

Compress the images

Compressing images is one of the most effective strategies for efficient encoding.

A lightweight WordPress plugin for image compression is ShortPixel Image Optimizer. With ShortPixel, you can automatically compress and optimize images as you upload them to your website. The plugin uses advanced compression algorithms to reduce file sizes by up to 90%, without a noticeable loss of quality.

ShortPixel offers both lossy, glossy, and lossless compression options, allowing you to choose the level of compression that best suits your needs.

Convert images to next-gen formats

Converting images to next-gen formats like WebP or AVIF is a solution to significantly reduce file sizes while maintaining high quality.

These formats offer superior compression efficiency compared to traditional formats like JPEG or PNG.

A straightforward method to harness the power of next-gen image formats is by using the aforementioned plugin, ShortPixel Image Optimizer. The plugin not only facilitates image compression but also boasts the capability to generate WebP / AVIF images and deliver them to compatible browsers.

Implement lazy-loading

Lazy-loading is a smart technique that delays the loading of images until they are needed, typically as the user scrolls down the page.

This approach prevents all images from loading at once, which can bog down page speed, especially on content-rich pages.

By implementing lazy-loading, you ensure that only the images visible to the user are loaded initially, reducing initial page load times and conserving bandwidth.

Several standalone WordPress plugins offer this functionality, one example being a3 Lazy Load. Additionally, many caching plugins incorporate lazy-loading functionality as part of their feature set.

Serve properly-sized images

Serving properly-sized images means making sure that your website displays images proportionate to the dimensions of the containers on the screen.

Oversized images can significantly impair your website’s performance, leading browsers to expend additional time downloading and rendering files, consequently inflating bandwidth usage.

Use a CDN

By distributing your website’s content across multiple servers worldwide, a CDN ensures fast and reliable delivery of your images and other media files to users around the globe.

All-in-one solution

Not keen on cluttering your toolbox with too many plugins? We understand.

To streamline and simplify your website optimization efforts, it’s best to consider an all-in-one solution.

FastPixel integrates all the recommendations mentioned above into a single, powerful toolset, besides other features.

With FastPixel, you can serve compressed images using advanced algorithms, ensuring optimal file sizes without compromising quality.

FastPixel converts images to next-gen WebP format, maximizing compression efficiency. It incorporates lazy-loading functionality, deferring image loading until needed. Additionally, it serves properly-sized images, ensuring proportional display on screen containers.

Last but not least, it includes built-in CDN support, enabling fast and reliable delivery of your website’s content to users worldwide.
