Importance of Web Image Optimization

Web image optimization is setting up your website’s images to provide visitors with the best possible user experience. A well-optimized image should be high-quality with the right format, dimension, resolution, and size while keeping the smallest possible size. There is great importance in optimizing images on websites.

We all know that images are essential for establishing a brand and representing ideas, people, and products. However, images continue to be one of the leading causes of poor performance and user experience. Below are the points that will describe the importance of optimizing web images:

• Enhances Page Load Speed: Images comprise 64% of your website’s weight. Thus, you can improve its speed if you optimize images. Moreover, optimizing web images is crucial because users prefer websites with fewer than two seconds of loading time.
• Improved SEO Ranking: Search engines can now index images and allow them to appear in search results. By optimizing your photos, you increase their chances of appearing in relevant search results.
• Increased Engagement: Page load speed is directly linked to conversions and search engine optimization ranking. It will give your visitors a better user experience, making them spend more time on your website.

How to Optimize Images For Web Performance

The key to successful image optimization for web performance is finding the ideal balance between the smallest file size and acceptable image quality. Image file format, image compression, and image dimensions are the three things that play a significant role in image optimization. You can reduce your image size by 80% by choosing the appropriate combination of these three factors.

Best Image Format For Image Optimization – JPG

Image optimization relies heavily on selecting the appropriate file type. JPG, PNG, and GIF are the three image file formats that are truly important. JPG is the best image format to keep things simple on your website. For those unfamiliar with file type differences, the PNG image format is uncompressed, implying a higher-quality image. In contrast, JPG is a compressed file format that slightly reduces image quality to provide a significantly smaller file size.

Advantages of Using JPG For Web Images

There are various benefits of using JPG file format for web images over the other ones. It is a lossy compression format, meaning the image quality is reduced when compressed. However, the loss is usually negligible, and the resulting file size is much smaller than other file formats, making JPG a good choice for storing and sharing images. 

High Compatibility

Most digital cameras have JPG as their default file format. It is also compatible with nearly all image viewers and browsers. These allow you to easily view your photos without converting them to another file format. Even some image editing software may only support JPGs. JPG images are compatible with almost all devices and software, including macOS, Windows, Photoshop, Linux, and Lightroom.

Smaller File Size

JPG produces smaller file sizes than other formats, such as PNG and TIFF. Their smaller file size makes them easier to store and share. This makes it ideal for web pages and online photo galleries. It can help with the number of images that need to be stored and the speed with which a web page loads.

Compression at Less Quality Loss

High compression rates can be achieved with minimal loss of quality. This makes JPG ideal for storing photographic images in a compressed format to save disk space and download time over the Internet. Because the compression algorithm is symmetric, decompression requires the same amount of computational power as compression.

Convert Your Image’s Format into A Perfect One

If you’re using other image formats than JPG on your website, you can convert them into JPG format immediately. There are many online image converters available that can transform your image’s format for free. Below are the steps that you must follow to change your image format to JPG:

• First, open your device browser and search for an online image converter.
• Then, open any of them and upload the image whose format you want to change.
• You can upload multiple images if the online image converter allows batch conversion.
• Once you upload the images, select the “JPG” file format and click the convert button to begin the conversion process.
• Wait for a while, and when the conversion process is done, click the download button to save the JPG image on your device.
