How to Save and Optimize Images for Web Performance?
The key to successful image optimization for web performance is to find the perfect balance between lowest file size and acceptable image quality.
The three things that play a huge role in image optimization are:
- Image file format (JPEG vs PNG vs GIF)
- Compression (Higher compression = smaller file size)
- Image Dimensions (height and width)
By choosing the right combination of the three, you can reduce your image size by up to 80%.
Let’s take a look at each of these process in more details.
1. Image File Format
For most website owners like you and me, the only three image file formats that really matter are JPEG, PNG, and GIF. SO Choosing the right file type plays an important role in image optimization system.
To keep things simple, you want to use JPEGs for photos or images with lots of colors, PNGs for simple images or when you need transparent images, and GIF for animated images only.
For those who don’t know the difference between each file type, PNG image format is uncompressed which means it is a higher quality image. The downside is that file sizes are much larger.
On the other hand, JPEG is a compressed file format which slightly reduces image quality in order to provide a significantly smaller file size.
Whereas GIF only uses 256 colors along with lossless compression which makes it the best choice for animated images.
On WPBeginner, we use all three image formats based on the type of image.
The next thing is image compression which plays a huge role in image optimization.
There are different types and levels of image compression available. The settings for each will vary depending on the image compression tool you use.
Most image editing tools like Adobe Photoshop, GIMP, Affinity Photo, and others come with built-in image compression features.
Although it’s a bit manual, these two methods allow you to compress images before uploading them to WordPress, and this is what we do on WPBeginner.
There are also several popular WordPress plugins like Optimole, EWWW Image Optimizer, and others that can automatically compress images when you first upload them. Many beginners and even large corporations prefer to use these image optimization plugins because it’s easy and convenient.
We will share more about these WordPress plugins later in the article.
3. Image Dimensions
Normally, when you import a photo from your phone or a digital camera, it has a very high resolution and large file dimensions (height and width).
Typically, these photos have a resolution of 300 DPI and dimensions starting from 2000 pixels and more. These high-quality photos are well-suited for print or desktop publishing. They are not suitable for websites.
Reducing file dimensions to something more reasonable can significantly decrease image file size. You can simply resize images using an image editing software on your computer.
For example, we optimized a photo with 1.8 MB original file size, 300 DPI resolution, and image dimensions of 4900×3200 pixels.
We chose jpeg format for higher compression and changed dimensions to 1200×795 pixels, and it reduced the image file size to 103 KB. That’s 94% less than the original file size.
Now that you know the three important factors in image optimization, let’s take a look at various image optimization tools for website owners.
