Images should be included in your WordPress content for a variety of reasons. Images keep viewers interested in your content. They can also be used to break up lengthy sections of material and enhance SEO (SEO). They could, however, make your page load more slowly.
Fortunately, there are several tools at your disposal that may assist you in optimizing your photographs. As a result, you’ll have a better chance of overcoming the poor page speeds that might harm your website’s overall performance.
We’ll examine why heavy graphics can be slowing down your website in this article. Then, we’ll look at how to efficiently compress your media assets and some basic picture optimization advice that can boost the SEO of your website.
Why You Should Be WordPress Image Optimization
Any content strategy should include images as a valued and crucial component. They could also be a significant contributor to sluggish page loads, though.
The issue with a sluggish website is that it may lose visitors.
In reality, image optimization aims to enhance two things:
the number of bytes required to encode each pixel in a picture.
the total amount of pixels utilised.
To put it another way, optimizing refers to obtaining the highest quality possible using the fewest pixels and bytes. This decreases the size of your media files and can significantly speed up your website.
Before uploading your images to WordPress, optimize them.
The ideal situation for your website is for you to optimize your photographs prior to uploading them. This prevents the creation of duplicates or numerous variants of the same picture. That would be contrary to the goal of image optimization, which is to reduce the load on your website.
In light of this, let’s examine some of the factors you’ll need to take into account when determining how to optimize the media on your website.
Picture Formats
Let’s look at the different categories of picture formats first to get things going. You may work towards a more efficient usage of pictures by comprehending how they differ from one another and when to employ each one.
The two most common image formats used online are JPEG and PNG. Both of these categories are made out of pixels. When you resize an image, the pixels elongate and might occasionally cause blurriness. These picture kinds do; however, each have distinct advantages and disadvantages.
Use Cases for JPEGs
JPEG files are a fantastic option for material on the web and in print. This type of picture file employs a “lossy” format. Some of the data in a bigger image’s file is lost when it is converted to a JPEG.
The image can be shown without using those data. What it does mean, though, is that while switching to a JPEG result in a lesser file size, there may be some overall image quality loss. Fortunately, the quality drop is barely perceptible, particularly for tiny photographs.
PNG Use Cases
Just like JPEGs, PNG files are beneficial for online content, but in a different way. PNGs are more adaptable and practical for creating online graphics because, for instance, they allow for translucent backgrounds.
PNG files are in a “lossless” format. This indicates that when the file is compressed, all of the image’s information is kept. They thus often offer a lesser boost in file sizes and page speeds but tend to be of higher quality. For graphics, icons, and really high-quality photos, they make a fantastic choice.
Picture Size
Time to reduce the bloat One of the easiest and most efficient methods to optimize your photographs is to deliver scaled versions of them. Why is it so powerful? Image scaling will make sure that you don’t transmit any more pixels than are required for the image to appear in the browser at its intended size.
Numerous websites attempt to serve huge, unscaled photos and rely on the browser to resize them, which uses more resources and slows down the site’s performance.
In light of this, the following are some best practices for exporting your images:
Save your images as “web optimized” JPEGs or PNGs to keep their file sizes to a few hundred kilobytes.
The 72 dots per inch (dpi) web standard for pictures can be met by storing images in the manner described above.
To shrink the image to a width of 1,500 pixels or smaller, use Photoshop, Lightroom, or a comparable editor. Simply choose Image > Image Size in Photoshop to manually change the image’s size and resolution. To prepare your photographs for online upload, you may alternatively go to File > Export > Save for Web:
You can shrink the image even more if you don’t want it to seem sharp and vibrant on a larger monitor.
To manually change the image size while exporting it in Lightroom, go to File > Export:
Just one piece of the puzzle are the image size and resolution. Understanding and successfully utilizing compression is very important when it comes to picture optimization.
Jpeg Compression
In a word, Jpeg Compressor is a tool for reducing the size (in bytes) of a graphic file without significantly lowering the image’s quality. High-resolution photos with excessively huge file sizes can significantly slow down pages, as we’ve already explained.
However, optimized photos often weigh 40% less than non-optimized photographs. All photos and other media that you add to your website should generally be optimized, either before or during the upload process.
Compression with vs. without loss
JPEGs and PNGs, as we just established, employ two distinct methods of picture compression. Without losing quality, lossless compression keeps all of the data from the original file.
Lossy compression, on the other hand, eliminates part of the data from the image file. This may lead to a greater decrease in quality but a greater increase in page speeds. To strike a balance between quality and performance, you may even alter the level of compression.
With Smush’s image compression plugin, all of your photos are resized, optimized, and compressed for the web, making them load more quickly than before. This plugin is essential if your website has a lot of images.
The Image Optimizer plugin from ShortPixel compresses all current and upcoming photos as well as PDFs that are submitted to your media library. For the majority of file formats, the plugin offers both lossy and lossless compression. Photographers may prefer the glossy JPEG compression because it employs a superior lossy optimization method.
