Many times it happens that everything is good on the website but when any visitor comes on the website, they experience a glue-footed walk through on the website. Usually, the main reason behind this is the use of less optimized images. Optimizing images is nothing but a process of reducing the file size without losing the image quality. Using optimized images in the website speeds up the page load time and generates a better user experience. Slight modifications in the images can improve the website performance drastically. Let us discuss some tricks and tips that can wisely optimize images without spoiling them.

There are 2 primary factors that are considered while optimizing the image:

1. File format

Prior to image modification, choosing the right file format is a major concern. There are many types of files formats that you can use:

Image file format

  •  PNG – It has a larger file size and generates high-quality images. Though it is supposed to be a lossless image format, sometimes it can become lossy.
  • JPEG – It uses both lossy as well as lossless optimization. The best part of this format is you can adjust the quality level to produce a viable balance between quality & the file size.
  • GIF – This format uses only lossless optimization. Since it only uses 256 colors, it forms the best choice if there are animated images.
  • There are other formats also like WebP and JPEG XR but not all browsers support them. For that reason, the above 3 formats are widely used, where PNG is for simple images and JPG is for images with plenty of colors.

 2. Type of compression

There are 2 types of compression:
A. Lossy – With this type of compression, the size of the file is reduced to a great extent but the quality gets spoiled. Since this can deteriorate the image, you really have to be careful about what extent to compress the image. If you want to perform lossy compression, you can use tools like Adobe Photoshop, Affinity Photo, or other image editors to tune the quality of an image.

B. Lossless – This compression does not reduce the quality of the image but it does require the images to be uncompressed before rendering. To perform lossless compression, you can use Adobe Photoshop, File Optimizer or Image Optimizer tools.

The sole aim to optimize image is to set a balance between the lowest file size & acceptable image quality. Both the factors discussed above go hand in hand to get the best output. Picking up the right format and compression type can reduce the image size by as much as 5 times. You need to experiment smartly to look for the best balance so that the image does not look ugly. But one thing which is most required here is optimum knowledge about the tools and web. If you are not confident of performing this on your own, you must hire Website Development Company in India to get the winning results.
