Best WordPress Image Optimizer Plugins

Home - WordPress SEO & Marketing - Best WordPress Image Optimizer Plugins

A picture is worth a thousand words. Images have the power to turn a plain and uninteresting design into a website that is vibrant and engaging. They can enhance and even improve your message when used with text, increasing visitor comprehension of the charm of your offer. However, the average image size is growing over time, which could prolong the load time for your visitors.

Images still matter for their aesthetic appeal, so you can’t just ignore them. Use image optimizer plugins to optimize your photos, resulting in significantly smaller file sizes and faster WordPress. Your website won’t load more slowly if you use WordPress image optimizer plugins to upload photos.

What is an image optimizer plugin?

Image optimization is the method of modifying an image to fulfill the needs of your website. Among the requirements are appropriate format, resolution, size, and dimension. Finally, the photos should be displayed not to hinder site performance or the user experience.

Required factors for image optimization

  • Physical space occupied by image: The device that your visitors use to view your WordPress site determines how much actual space your images take up.
  • Data size: This represents how much data the file uses when it is in its original state.
  • Aspect: This refers to an image’s pixel count. The clarity of the image increases with resolution.
  • Data format: This is the type in which your image was stored. Typically, when we refer to images, we refer to PNG, JPG, SVG, and GIF files.

The main objective of image optimization plugins is to shrink image files without significantly lowering their quality. To do this, several methods are available.

  • Image Resolution Reduction – shrinking the width and height of an image.
  • Use lossless compression to minimize the size of your photographs, either individually or in bulk (no image quality is lost).
  • EXIF metadata removal – EXIF metadata, including creation date, shutter speed, copyright information, geolocation, and others, are eliminated.
  • Image Compression – Compress to improve but not degrade the image quality.
  • Change Image Format – Change an image’s format to one that is more resourceful.

Why Do You Need WordPress Image Optimizer Plugins?

Unoptimized images can slow down your site. Google considers website speed a search engine ranking factor, so loading speed is key to outranking your competitors and attracting more traffic to your site. An image compression plugin enables you to optimize the images and helps you to load your site faster.

  • Bulk Optimization: All your images should be able to be optimized simultaneously.
