How to Save and Optimize Images for Web Performance? How to optimize images for the web without losing quality
The key to successful image optimization for web performance is to hunt out the proper balance between the 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 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 only 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’d wish to use JPEGs for photos or images with many colors, PNGs for straightforward images, or once you would like transparent images and GIF for animated images only.
For people who don’t know the difference between each file type, the PNG image format is uncompressed which suggests it is a better quality image. The downside is that file sizes are much larger.
On the other hand, JPEG could also be a compressed file format which slightly reduces image quality so on 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 WEhavedigitaltool, we use all three image formats to support the sort of image.
The next thing is compression which plays a huge role in image optimization.
There are different types and levels of compression available. The settings for each will vary relying on the compression tool you use.
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 online tool like TinyPNG or JPEG Mini for easier compression.
Although it’s slightly manual, these two methods allow you to compress images before uploading them to WordPress, and this is often what we do on WEhavedigiltool.
There are also several popular WordPress plugins like Optimole, EWWW Image Optimizer, et al. which will automatically compress images once you initially 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, once you import a photo from your phone or a camera, it is a really high resolution and massive 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 publication. They are not suitable for websites.
Reducing file dimensions to something more reasonable can significantly decrease image file size. You can simply resize images employing 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% less than the original file size.
Now that you simply simply simply know the three important factors in image optimization, let’s take a glance at various image optimization tools for website owners.
