How to Optimize WordPress Images Without Losing Quality

When someone starts a new blog, the primary focus remains on making blog attractive and adding content. So people simply upload images without taking much care of resolution or size. But large images affect the load time and make the website slower.

Why is image optimization important?

Images are an important part of blogs but they also make the website heavy and affect the loading time. If you use images that are big in size, they increase the website load time. Since site performance and speed are an important factor in Google’s ranking, we must take care of image optimization.

Too many large images also increase bandwidth usage and also consume more space on your hosting server.  So not just for SEO, image optimization is also good for reducing server costs.

What is Image Optimization?

Image optimization is the process of reducing the size of an image without affecting the overall image quality. Obviously, the optimization process reduces the quality a bit, but that won’t be noticeable. Optimized images could be up to 75% smaller than the original without any significant loss in quality.

Optimize WordPress Images Without Losing Quality

Here are a few ways to optimize WordPress images without losing quality. You need to follow each step for better results.

File Formats

There are various different image file formats including JPEG, GIF, and PNG. Here, JPEG images should be your first choice. This format contains many colors and also uses compression in order to reduce the file size. It uses lossless compression techniques so retain the high quality but reduces the image size. So, try to use this file size for the images you upload.

Now several websites have also started using Google’s WebP image format that offers the same image quality but in up to 25 times lesser image size. The only issue with WebP is that it is not widely supported. Firefox and Safari are yet to support it. You can still use WebP in supported browsers without breaking your website. I have posted an in-depth guide on setting up WebP images in WordPress.
