2- EWWW Image Optimizer

EWWW Image Optimizer - Best Image Optimization Plugins for WordPress

EWWW Image Optimizer is a free WordPress plugin that optimizes images on the fly as they’re uploaded. In other words, when you insert an image into a post via WordPress’s media manager, it will already be optimized before it’s even saved to your server.
The plugin is written in JavaScript and uses several open-source libraries to do its job. All you need to do is install it, go to Settings > Media and tick Automatically optimize new images. The image optimizer takes care of everything else. After that, EWWW will even convert PNGs into a format appropriate for Web usage (using ImageMagick). This can save space and improve the load times of images that appear on your site.
Plus, it’s easy to use: just install, set up, and forget about it. As stated above, there are no settings to configure or options to tweak! There is also a nifty bulk optimization tool that lets you select multiple images from your media library at once.

3- ShortPixel Image Optimization Plugin

4- Fast Velocity Minify

Fast Velocity Minify - Best Image Optimization Plugins for WordPress

Like most Image Optimization Plugins, this one has a free version that allows you to compress one image per day. The free version is useful if you want to test its features and get a feel for how it works. But I highly recommend purchasing a commercial license if you plan on using it frequently. It supports batch processing. This means you can process multiple images at once and allows you to adjust compression settings without slowing down performance. Just make sure your server supports GD2 because that’s what Fast Velocity Minify uses by default.

The plugin offers a ton of customization options so you can customize how your images are compressed without sacrificing performance. While it supports batch processing and lossless optimization, so you can optimize high-quality images quickly.

The only downside is that it doesn’t support GIF or SVG format. But most modern web browsers support PNG format these days.

Of all of these image optimization plugins, Optipole stands out as one of our favorites. It’s a lightweight plugin that does a great job with JPEG optimization.

Optimole also is using an image CDN, this will help your images to load quickly no matter where your visitors are. With the CDN integration, your website images are quickly optimized in real-time and delivered to your visitors in the ideal size.
