What does it mean to Optimize Images?
If you ever received a recommendation to optimize images by your WordPress hosting support or by a speed test tool, then all it means is that you simply got to reduce file size of your images by optimizing them for website.

How to Optimize Images for Web Performance?
The key to successful image optimization for web performance is to seek out the right balance between lowest file size and acceptable image quality.
The three things that play an enormous 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 proper combination of the three, you'll reduce your image size by up to 80%.
Let’s take a glance at each of those in additional detail.
1. Image File Format
For most website owners, the sole three image file formats that basically matter are JPEG, PNG, and GIF. Choosing the proper file type plays a crucial role in image optimization.
To keep things simple, you would like to use JPEGs for photos or images with many colors, PNGs for easy images or once you need transparent images, and GIF for animated images only.
For those that don’t know the difference between each file type, PNG image format is uncompressed which suggests it's a better quality image. The downside is that file sizes are much larger.
On the opposite hand, JPEG may be a compressed file format which slightly reduces image quality so as to supply a significantly smaller file size.
Whereas GIF only uses 256 colors alongside lossless compression which makes it the simplest choice for animated images.
On WPBeginner, we use all three image formats that supported the sort of image.
The next thing is compression which plays an enormous role in image optimization. There are different types and levels of compression available. The settings for every will vary counting on the compression tool you employ . Most image editing tools like Adobe Photoshop, On1 Photo, GIMP, Affinity Photo, et al. accompany built-in compression features.
You can also save images normally then use an internet tool like TinyPNG or JPEG Mini for easier compression .
Although it’s a touch manual, these two methods allow you to compress images before uploading them to WordPress, and this is often what we do on WPBeginner.
There also are several popular WordPress plugins like Optimole, EWWW Image Optimizer, et al. which will automatically compress images once you first upload them. Many beginners and even large corporations like better to use these image optimization plugins because it’s easy and convenient.
We will share more about these WordPress plugins later in this article.
3. Image Dimensions
Normally, once you import a photograph from your phone or a camera , it's a really high resolution and enormous file dimensions (height and width).
Typically, these photos have a resolution of 300 DPI and dimensions ranging from 2000 pixels and more. These high-quality photos are well-suited for print or publication . They're not suitable for websites.
Reducing file dimensions to more reasonable can significantly reduce image file size. you'll simply resize images using a picture editing software on your computer.
For example, we optimized a photograph 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 altered dimensions to 1200×795 pixels, and it reduced the image file size to 103 KB. That’s 94% but the first file size.
