5 Easy Methods to Optimize Images for Faster Loading

1. Convert Images to the Best Format

Using the best image file format is very important for any website as it significantly influences the loading speed of the website. However, compressing the image for faster loading should not compromise the quality of the image. So image optimization should be about reducing the size of image files while balancing any loss of quality. 

The best image formats for websites are WebP and AVIF. These image formats provide better compression than the traditional PNG or JPEG. WebP and AVIF image file formats have high-quality images that are light in weight. 

2. Use an Image Compression Tool

Image compression tools effectively reduce image file sizes while preserving the image quality. Using image compressing tools helps to optimize images for faster loading as it consumes less internet bandwidth. 

Image compression tools use an algorithm to reduce image file size. Depending on whether the image file format is lossy or lossless, the tool will remove the unnecessary data from the image file. PNG and JPEG files can be lossy or lossless depending on the source image while GIF uses lossless file compression.

We suggest you use an image compression service like to reduce the image size without losing the real quality. Using these compression services will slow and help you load your WordPress page/post much faster. 

3. Enable Browser Caching

Image caching is one of the most efficient strategies to optimize images for faster loading. Caching means storing frequently used data so it is easily accessible to users such as images, scripts, stylesheets, or fonts. So, when our visitors visit your website, they don’t have to load the same resources again and again. 

Therefore enabling browser caching helps to optimize images for faster loading by saving bandwidth. You can use WordPress caching plugins like W3 Total Cache or WP Super Cache

4. Disable Hotlinking 

Whenever you use the image from another website it is better first to download it and then upload it on your WordPress website. (Make sure you have proper rights and permission to do so). But this doesn’t happen as some websites are guilty of ‘hotlinking’.

Hotlinking happens when a third party links to an image that’s hosted on your server. So whenever the third party’s site loads the image, it easts into your bandwidth. 

Hotlinking degrades your website’s performance without even delivering any page views. Therefore, to prevent other sites from consuming your bandwidth, you can disable hotlinking using plugins like All In One WP Security & Firewall

5. Serve Images Through A Content Delivery Network (CDN)

While selecting the host and plan for your website, you have selected the data center location. For instance, your website may be physically located in London. 

When data has to travel longer distances, it can cause latency. More the distance, the longer it takes to load the site. So, a Content Delivery Network (CDN) reduces the latency caused by geographical distances. 

Using a reliable CDN provider can help you optimize images for faster loading. A CDN lets you serve your images faster to international users and can fix many PageSpeed Insights issues. A few popular CDN providers are Sucuri, KeyCDN, and Cloudflare.
