Are you looking to improve your website speed to enhance SEO? To do that, you need to implement many tasks. An important part of improving website speed is optimizing images before uploading them to your WordPress site. Image optimization is recommended because a lot of reasons:

  • This makes your site speed become faster

  • Saving the bandwidth and storage
  • Website backups will be faster
  • Reducing hosting, CDN, and backup storage cost

So, in the blog today, we will show you simple but effective ways to optimize images in WordPress without losing their quality. Let’s take a look!

How to Optimize Images in WordPress

The most important thing that helps you optimize images successfully is creating a balance between the lowest file size and good image quality. The three factors play a vital role in the image optimization process including:

Image file format

You need to select the right image file format among 3 formats (PNG, GIF, and JPEG) for your site. Simply put, use JPEG for images with multiple colors, PNG for simple or transparent images, and GIFs for animated images. All three of these image file formats have their own advantages and disadvantages.

As for PNG, although the image is high quality, it is not compressed. Therefore, the file size is quite large. JPEG, on the other hand, gives you the image as a compressed file. However, the image quality will be slightly degraded. That means the file is smaller in size. GIF comes with 256 colors combined with lossless compression, making it the perfect choice for animations.


Another factor that is also very important in the image optimization process is compression. Currently, there are many different types and levels of image compression. Some famous photo editing tools such as Adobe Photoshop, On1 Photo, Affinity Photo, etc, all integrate image compression. Alternatively, you can also save the image on your computer and use a web tool like JPEG Mini or TINyPNG to compress the image.

In addition, nowadays, on the market, there are many WordPress Optimized Images Plugins that help you compress images as soon as you upload them. This is the method loved by many WordPress owners because it is quite easy, convenient, and time-saving.

Image dimensions

Reducing file dimensions to a reasonable extent will also help you to optimize images effectively.

By default, images from a digital camera will have high resolution (about 300 DPI) and large file dimensions (2000 pixels or more). With such images, it is often used for printing or installing on the desktop. A website does not need to have such high-quality images. Therefore, what you need to do when encountering such images is to reduce the file dimensions by using image editing software.
