Images. They make your website more receptive to the readers. Without proper images, your content delivery might not be accurate or as impactful as you think.

In today’s article, we will cover a detailed guide on image optimization. If you plan to build a blog, then this guide will also help you.

Is it essential to optimize images?

Image optimization is important. First, it makes your website load faster. You don’t want a bulky 2 MB image file slow down your website. Secondly, it helps you rank better in Google as Google loves a faster website that offers great user experience. Moreover, optimizing images also mean that you also mean that your website will have less bounce rate.

However, before we start with the actual guide, let’s list the type of image formats that you should about.

Type of Image Formats

Images Formats for WordPress

There are two main types of image formats that you will encounter in your day-to-day WordPress activity. They are JPEG and PNG. You can identify them simply by looking at their extension. JPEG ends with .jpeg whereas PNG ends with .png. Regarding performance, JPEG beats PNG. However, if you are looking for quality, PNG holds the key.

PNG is ideal for high-quality places where you just cannot compromise the quality. For example, you can use it for logos, limited color images and so on. For daily blog activity, it is always advisable to go with JPEG as it saves you a ton of size and doesn’t have much difference in quality.

Tips to Optimize Images for WordPress

Now that you know which image format you need to choose, it time to optimize them.

Resize Before Uploading

After you choose the image you need to upload, it is a better idea to resize and compress them before uploading to WordPress.

Every website has its image requirement. Some website like image width to set to 800px, whereas others are more focused on having an image size of 600px. To know what image size you need, check out the theme documentation. It will surely contain the image size that you will need.

Resizing is important because it cuts out the unnecessary image size. You can save more than 60% of the image size by doing so.

To resize and optimize image before uploading, we suggest ResizeImage.net. However, if you want to optimize image from WordPress itself, then you can do it by resizing the image from the WordPress Media Library (WML).

After you open your WML, you need to select the image and then click on “Edit Image.” After picking a new dimension, click on “Save” to complete the process.

Resizing the image from the WordPress Media Library (WML).

Automate Image Resize When You Upload

If you are a little lazy and don’t want to do any of the manual resizing, then you can make use of Imsanity plugin. The plugin automatically resizes the image when it is uploaded. As a user, you can set the width, height and other factors that define the quality of the image.

Also, you don’t have to worry about your previous unoptimized images as you can also do bulk resize using this plugin.

Using Image Optimization Plugins for WordPress

Resizing and optimizing images are a different thing. And, that’s why we are now going to discuss the optimization part. By optimizing the image, the images will load faster with no loss in quality.

The good news is that WordPress comes with tons of plugins for image optimization. To make it easy for you, we are going to list only a few of the plugins. However, before we start, we need to understand two important terms related to image optimization.

Lossy Compression: Lossy compression means that the image is compressed, the data is lost. This means that the original image cannot be retrieved anymore.
Lossless Compression: Lossless compression is a compression technique by which the original image data is not lost even after compression. This means you can retrieve the original image from a compressed image.

Let’s now discuss the WordPress image optimization plugins.

Another big reason we recommend WP Smush is its ability to optimize image regardless of the folder it is stored in. This means that every image on your website will be optimized. Furthermore, it adds them to your media library automatically.

However, there are few limitations in the free version. The free version won’t let you optimize images bigger than 1 MB. This can easily be avoided by only uploaded resized images or using TinyPNG.com. Another limitation is that you cannot choose the compression technique for the images.

Image optimization should never be taken lightly. If you don’t do it correctly, you will not only lose audience but also start losing Google rankings. You should also take care of other factors such as having a good hosting, using a proper theme and using less number of plugins. After only you combine all the factors, your website will be fast enough for visitors to enjoy.
