What is Image Optimization function?

In simple terms simply put, image optimization uses compression techniques like "Lossy" and "Lossless" that help reduce the overall size of the file, without noticeable loss of quality.

What is it to Optimize Images?

If you've ever been given a recommendation to optimize images by your WordPress hosting support , or the speed test tool, that's all it means is that you need to reduce the file size of your photos by optimizing them for the web.

Why is Image Optimization Important? What are the Benefits of Image Optimization?

There are many advantages from optimizing your images below are some of the best that you should know:

  • Speedier website loading
  • Enhanced SEO rankings
  • Conversion rates that are higher for sales and leads
  • Reduced storage and bandwidth (which could lower hosting and CDN cost)
  • Faster backups of websites (also decreases the cost of backup storage)

Outside of video, images represent the next biggest weight on a web page. From the HTTP archivedata, photographs comprise about 21% on average of the total weight on a web page.

Since we know fast websites rank higher on search engines (SEO) and achieve higher conversions, image optimization is a necessity for every business website should do in order to grow online.

How to Save and Optimize Images for Web Performance?

The key to successful optimization of images for optimization that is optimized for performance on websites is to find the perfect ratio between the smallest size of the file and acceptable image quality.

The three things that play a crucial influence on Image optimization are:

  • Image file format (JPEG vs PNG vs GIF vs tiff )
  • Compression (Higher compression = smaller file size)
  • Image Dimensions (height and width)

If you select the most appropriate combination of these three options, you can reduce the image's size by as much as 80 percent.

Let's look at each one in more detail.

  1. Image File Format

For the majority of webmasters, the three primary images formats that really have any significance is JPEG, PNG, and GIF. The choice of the correct file format is crucial to image optimization.

To simplify things To keep things simple, you should use JPEGs when you want to use images or photos filled with colors. PNGs to create simple images, or when you require transparent images. You can also use GIF for animated images only.

For those that don't know the difference between each type, PNG image format is not compressed which means it's a more high-quality image. The disadvantage is that it's file dimensions are larger.

However, JPEG is a compressed file format , which can slightly diminish the image quality to make it much smaller file size.

The difference is that GIF only uses 256 colors and lossless compression. This makes it the most suitable choice for animated images.

On WPBeginner We make use of three different image formats based on the kind of image.

2. Compression

The next step is image compression which plays a huge part for image optimization.

There are many types and levels of compression that are available. These settings differ based on the compression tool you employ.

The majority of image editors, including Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and many others have built-in features to compress images.

You are also able to save images and then make use of a website tool like TinyPNG or JPEG Mini for easier image compression.

Though it's a little manual but these two techniques allow you to compress your images prior to uploading the images to WordPress as well, which is the process we employ on WPBeginner.

There are also a variety of popular WordPress plugins like Optimole, EWWW Image Optimizer and many more that automatically compress images once you upload them for the first time. Many newbies, and even larger corporations choose to use these image optimization plugins due to their ease of use and efficient.

We'll discuss more details about these WordPress plugins later in this article.

3. Image Dimensions

Normally, when you download a photograph from your phone , or digital camera, it has a very high resolution and the dimensions of the file are large (height and width).

The majority of these photos have resolutions of 300 DPI with dimensions starting from 2000 pixels and up. These high-quality photographs are great for desktop or print printing. They're not suitable for use on websites.

A reduction in file dimensions to something more acceptable can dramatically decrease the size of the file. Resize images by using the software for editing images on your computer.

In this case, we optimized a photo with 1.8 megabytes of original file size With a 300 DPI resolution, and dimensions of 4900x3200 pixels.

We went with the JPEG format for greater compression. We also changed the dimensions to 1200x795 inches, and it reduced the file size to 103KB. That's 94% less than the original size.

Once you've mastered the three primary factors that affect image optimization we can take a to look into various images optimization tools for website owners.

Best ImageOptimization Tools and Programs

As we have mentioned previously, most image editing software come featuring image optimization along with compression and image optimization settings.

Outside of the image editing software, there are several other powerful , free image optimization tools that you could apply to optimize images for web usage (with just one or two clicks).

We recommend making use of these tools for optimizing images prior to uploading them to WordPress particularly if you are a perfectionist.

This method will help you save the disk space of your WordPress hosting account and also guarantees an image that is fast and of the best quality since you have to manually check each image.

Adobe Photoshop

Adobe Photoshop is a premium software with the ability to save images specifically designed for the web. Simply open the image, then click on the "File >> Save for Web" option.

This will open an additional dialog box. On the right, you can set different image formats. For JPEG format, you'll see different quality options. When you pick your option it will also give you the size of the image in the lower left.

GIMP

GIMP is a free and open-source alternative to the popular Adobe Photoshop. It can be used to improve your image for the web. However, it's not as simple to implement as other solutions listed here.

The first step is to open the image in GIMP before you can select the File > Export As option. It will open the save file dialog box. Then, give the file a brand new name and then hit"export.

This will present options to export images. When you export JPEGs, you can select the compression option to reduce the size of the file. In the end, you can click on an export option to download the image you have optimized.

TinyPNG is a completely free web application that employs a clever lossy compression method to minimize the size of your PNG files. All you need to do is go to their website and upload your images (simple drag and drop).

They compress the image and then provide you with the download link. You can also visit their sister websitecalled TinyJPG which is for JPEG Image compression.

There is also one extension that works with Adobe Photoshop which we use as part of our image editing process since it is a blend of TinyJPG and TinyPNG inside Photoshop.

For developers, they've an API to convert images for them automatically. And for beginners , they provide an WordPress plugin that can do it for you (more on this later).

JPEG Mini

JPEGmini employs lossless compression process that drastically reduces the size of images without any impact on their perceived quality. You can also check the quality of your original image and the compressed image.

You can use their web version for no cost or buy the program to run on your personal computer. There is also a paid API that will automate the process that your server uses.

ImageOptim

ImageOptim is a Mac program that allows users the compression of images with no losing any quality. This is done by identifying the most effective compression parameters as well as removing unnecessary color profiles.

Windows an alternative is Trimage.

As technology actively develops as it does, criminals are using ever more sophisticated techniques to steal our money. We often get short messages in the mail or on our mobile device that contain images or software that could "interest us", but in reality, they're malware that can take over our devices or computers. For example, you can create your advertisement on an advertising platform about selling a product. You will receive an email within a couple of hours that includes an offer to exchange your item for a different one. The text also includes a link to pictures of the item. It is possible to download the specific software when you click this link on an Android phone. It will then transfer your entire money into the bank account of the intruder. Another common method for committing attacks is to send mail messages using the text and link, which stimulates user to open this link. It is possible that you will be approached by an attacker, and must complet...
