How to Optimize Your WordPress Images using image compression.
You would (and should) integrate images in your WordPress post for a variety of reasons. Images assist to keep your readers interested. They’re also a good technique to break up large chunks of material and enhance SEO (SEO). They can, however, cause your website to load slowly.
Fortunately, there are several tools available to assist you in optimizing your photographs. This means you’ll be more likely to overcome poor page speeds, which can be damaging to your website’s overall performance.
In this post, we’ll look at why huge photos may be slowing down your site. Then, we’ll look at how to successfully compress your media assets, as well as some basic picture optimization strategies that can help your site’s SEO.
Why You Should Optimize Your WordPress Images
Images are an essential component of any content strategy. They can, however, be one of the primary causes of delayed website loading times.
A sluggish website is a concern since it might drive away visitors. In fact, sites that take five seconds or longer to load have a 90% increase in the likelihood of a visitor bouncing (leaving after only viewing a single page).
Image optimization is primarily concerned with two aspects:
The number of bytes required to encode each picture pixel.
The total amount of pixels that were utilized.
In other words, optimizing is achieving the greatest quality possible from the fewest pixels and bytes. This minimizes the size of your media files and can have a substantial influence on the overall performance of your site.
Before uploading images to WordPress, optimize them.
Finally, optimizing your photographs before uploading them is the best-case scenario for your website. This is done to avoid having duplicates or numerous copies of the same image. That would negate the objective of image optimization in lightening the load on your website.
With that in mind, let’s take a look at some of the factors to consider when selecting how to optimize your site’s media.
Image File Extensions
To begin, let’s look at the numerous types of picture formats that exist. Understanding how they vary and when to utilize them will help you get towards a more simplified usage of pictures.
JPEGs and PNGs are the two most frequent image formats used online. Pixels are used in each of these forms. When you modify the scale of an image, the pixels expand, causing it to become fuzzy. These visual forms, however, have various strengths and limitations.
When Should You Use JPEGs?
JPEG files work well for both print and online content. This type of picture file employs a ‘lossy’ format. Some of the information in a bigger image is lost when it is converted to a JPEG.
That information isn’t required to display the image. However, converting to JPEG results in a reduced file size, but there may be some compromise in overall image quality. Fortunately, the quality loss isn’t too evident, especially with tiny photographs.
When Should You Use PNGs?
PNG files, like JPEGs, are valuable for online content, but in a different way. Because PNGs, for example, may have translucent backgrounds, they are more adaptable and useful for developing online images.
PNGs are saved in a ‘lossless’ format. This implies that when the file is compressed, all of the image’s information is preserved. As a result, they are of greater quality yet provide a marginal improvement in file sizes and page speeds. They’re an excellent choice for graphics and icons, as well as really high-quality photos.
It’s time to trim the fat. One of the easiest and most efficient ways to optimize your photographs is to deliver scaled images. Why is it so effective? Image scaling ensures that no more pixels are shipped than are required to show the image at its intended size in the browser.
Many sites attempt to serve huge, unscaled pictures and rely on the browser to resize them, resulting in the need of additional resources and a slower site performance. If the image’s native size is 820820 pixels and the browser displays, it as 400400 pixels…32,400 that’s extra pixels!
With that in mind, here are some best practices for exporting your images:
Save your images as ‘web optimized’ JPEGs or PNGs to keep file sizes under a couple hundred kilobytes.
The online standard for photos is 72 dots per inch (dpi), which may be obtained by storing images in the above-mentioned format.
You may trim the image size to roughly 1,500 pixels or fewer in width using Photoshop, Lightroom, or a comparable editor. Simply go to Image > Image Size in Photoshop to manually modify the size and resolution of your image. To optimize your photographs for online upload, click to File > Export > Save for Web:
You can reduce the picture size even lower if you do not want to display crisp and vibrant photographs on a larger monitor.
If you’re using Lightroom, go to File > Export to manually alter the image size after you’ve exported it:
Image dimensions and resolution are only one piece of the jigsaw. When it comes to picture optimization, you’ll also want to understand and employ compression properly.
Compression of Images
In a word, image compression (also known as jpeg compressor) is a method of reducing the size (in bytes) of a graphic file while maintaining acceptable picture quality. As previously noted, high-resolution photos with excessively large file sizes can have a significant impact on page performance.
Optimized photos, on the other hand, are 40% lighter than unoptimized images on average. As a general guideline, you should optimize any photos or other material that you post to your website before or during the upload process.
Compression (Lossy vs. Lossless)
JPEGs and PNGs, as previously stated, employ two distinct forms of picture compression. Lossless compression keeps all of the original file’s data without affecting quality.
Lossy compression, on the other hand, loses part of the data included in the picture file. This can result in a bigger reduction in quality but also a considerable increase in page speeds. You may even adjust the degree of compression to strike a balance between quality and performance.
Smush’s image compression plugin resizes, optimizes, and compresses all of your photos for the web, allowing them to load quicker than before. If your website has a lot of photos, this plugin is a must-have.
The Image Optimizer plugin by ShortPixel compresses all previous and future photos and PDFs submitted to your media library. For most file formats, the plugin offers both lossy and lossless compression. If you are a photographer, you may want to utilize the glossy JPEG compression, which employs a high-quality lossy optimization method.
