Why optimize images for your WordPress blog
Why optimize images:
Are you running a WordPress website or blog, and your website page load time is high due to large images? Don’t worry, it is a common problem, and many of the WordPress website owners pay very little attention to this fact.
Since Google has attached website ranking with page load time, it has become critical for everyone.
Optimizing your images not only helps your WordPress website load faster, but it also boosts your SEO many folds.
High-resolution images that are unnecessarily large in file size can drastically slow down your website speed and ultimately leads to a drop in search rank and loss of traffic.
Fortunately, you can solve this problem without wasting much of the resources and time. It is possible to reduce the image size without losing quality.
In the following section, we will look into some of the best methods and plugins available to achieve the best results.
Scale Your Image
The first and foremost important step is to determine the size of the image you need for your article or web page.
If you want to show the image in 600px into 600px box, it does not make any sense to upload large image with dimensions 1920px into 1240px. It will not help you to achieve excellent results.
Put your image in Photoshop or Paint, size it as per your need, and export it. It will reduce the file size.
Compressor.io is a powerful online tool for reducing the size of your images and photos drastically while maintaining a high quality with almost no difference before and after compression.
It supports four file formats: JPG, PNG, GIF and SVG along with lossless and lossy compression.
It is a magical tool! If you are not using this, you are losing a lot in terms of page speed.
Compressor.io makes sure that your image is fully optimized, and it does not affect the image quality.
We have been using this for our website to optimize images, and it is phenomenal.
Use this tool to compress your image file size further.
WP Smush is, undoubtedly, the fastest, most user-friendly, and best-performing image compression plugin for WordPress.
It allows you to compress JPG, GIF, and PNG images up to 32MB individually or in bulk.
Leverage Browser Caching
When a web browser displays your webpage, it has to load several things like your logo, your image files, and other resources.
When you leverage browser caching, your webpage files will get stored in the browser cache. Your pages will load much faster for repeat visitors, and so will other pages that share those same resources.
Meanwhile, if you change any of those files, the server will tell the user’s browser to clear that cached file and download a new record.

WP Super Cache
W3 Total Cache has many advanced features as compared to WP Super Cache.
If you want full control of your website caching, I would recommend installing the W3 Total Cache plugin.
It has page cache, database cache, object cache, browser cache, and many more top features like CDN integration.
But if you are looking for a minimal and easy to use a cache plugin, go for WP Super Cache. This plugin generates static HTML files from your dynamic WordPress blog.
After an HTML file is generated, your web server will serve that file instead of processing the comparatively more substantial and more expensive WordPress PHP scripts. It will improve your page speed drastically.
Images Lazy Load
Lazy loading is the final step of image optimization for the WordPress website.
The idea behind it is “Load images only when required.” It does not make sense to load all the images when the page loads.
With lazy loading, you only load those images which are currently in browser window viewport at the start.
When the user scrolls down, the plugin automatically downloads the images and displays them to the user. It makes your site load faster and saves a lot of bandwidth.
BJ Lazy Load plugin is one of the excellent free plugins which does the job of lazy loading.
It replaces all post images, post thumbnails, gravatar images, and content iframes with a placeholder and loads the content and optimize images.
It also works with text widgets.
