6 Best Image Optimizer Plugins WordPress (Most Popular 2021)
The first thing you should do to speed up your site is optimize your images. Images play an important role in the design of your website. They aid in bringing in new readers and assist make your posts more engaging. There are many WordPress blogs on the web that use image optimization, and it’s critical to a well-ranked website in the search engines.
What are the benefits of image optimization for your WordPress website?
It can greatly reduce the time it takes for your site to load.
This is accomplished by compressing the image files, lowering the resolution to the minimum required, and removing any unnecessary metadata (information such as when the picture was taken, what device was used etc).
Faster loading times are made possible by optimizing photos, and as your site’s loading speed rises, so does its Search Engine Optimization (SEO). The alt and title tags that you add to your photographs can help your site rank well. As search engines pick up key terms when searching the web, including tags with keywords in them will help your post be found more easily. Google’s ranking algorithm also takes into account the time it takes for a page to load, thus the speed of your website is critical.
Using plugins and automation, this process can be sped up considerably.
Before using any of these plugins, check to see if:
You can only upload images that are as large as you need them to be. Depending on the size of the photos on your webpage, your page may take longer to load. Unnecessarily huge photos, especially those with high resolutions, use up resources and slow down your page’s loading time. Your website will load faster if the photos are scaled down in size or compressed. Images can be compressed to reduce file size by removing information that isn’t necessary, including the date and type of camera used during capture.
The picture names you provide are related to your submissions. This will help your search engine optimization efforts. In search engine results, images with descriptive titles have a better chance of being found, which helps you optimize your content and drive more visitors to your site. To do this, simply add a keyword to the image’s title in the image’s filename.

With over 300,000 active installs, Imagify is a well-known and effective WordPress plugin for image optimization.
Is there a rationale for its enormous acclaim?
This plugin, on the other hand, provides you a lot of power and freedom over picture optimization. As a bonus, it transforms your photos to the next-generation WebP file format.
Image Enhancement Evaluation Using Imagify
Somehow, Imagify decided that the JPG picture was already optimized and didn’t need any more compression. The PNG picture was compressed by 98.02 percent, from 1.65 MB to 33.55 KB. It compresses PNG images using aggressive lossy compression techniques.
What’s Great About Imagify?
You may choose between lossless and lossy picture compression with Imagify. As a result, you have a great deal of control over how well picture quality and image size are balanced.
When optimizing a picture, you have the option of converting it to WebP format as well.
It also works with all major picture file types, so you won’t have any problems with compatibility difficulties.
The WordPress backend even has an image resizer you may use to alter the picture’s proportions.
Is There Anything Negative to Say About Imagify?
While this isn’t the worst thing about Imagify, it is a significant drawback. Even for a new site, that’s quite low.
The average size of an unoptimized image on the internet is about 1 MB. You can only use the plugin to improve the quality of up to 25 high-quality photos each month.
With the free version, you may optimize up to 25 MB of pictures each month at no cost. You’ll have to subscribe to a premium plan if you want anything more.
Create a price illustration in your mind.
Plans start at $4.99 per month for optimizing 1 GB of pictures and go up to $55.99 per month for optimising 50 GB of images.
Plans for yearly subscriptions and one-time payments are both available.
When it comes to Imagify’s features, it’s hard to beat. With a monthly image optimization limit of only 25 MB for free users, it forces you to pay for a subscription.
As a result of these substantial picture optimization limits, Imagify is a great value for the money.
EWWW Image Optimizer
EWWW Image Optimizer is different from other image optimizers in that it optimizes just certain parts of your photos. Most image optimization plugins, such as ShortPixel and Imagify, use an API to connect to external servers to optimize images there.
EWWW Image Optimizer, on the other hand, optimizes the pictures on your own server. As a result, it’s free to use indefinitely, but you’ll have to put up with utilizing your own server resources to do so.
As a result, the plugin also provides you the option of connecting via an API (if you pay), so you may select the strategy that works best for you.
My testing are conducted on the self-hosted version for the sake of comparison.
Use your own server to optimize pictures, or connect to the API to use cloud optimization.
Improves the quality of JPG, PNG, GIF, and PDF images.
You have a choice of four compression settings, but not all of them are free.
Image resizing to the maximum possible size is automated.
Resize and dynamically serve pictures to a user’s device using a CDN (like ShortPixel’s adaptive images). This is a for-profit service.
Schedule optimization to run at a specific time of day, allowing you to save server resources by running it during non-peak hours.
Convert PNG to JPG and vice versa.
The process of generating and serving WebP graphics is described here.
EWWW Image Optimizer’s UI has just been redesigned and looks much better.
It does, however, provide a plethora of configuration options. That’s actually a good thing. All those choices will appeal to people who appreciate having fine control over their environment. On the other hand, if you’re a first-time user, you could be daunted (in which case I would recommend something like ShortPixel or Imagify).
For instance, the UI has a plethora of tabs:
Settings for EWW’s Image OPtimizer
Maximized Lossy Strict
The image is a JPG of unknown origin, size.
To view the full-size image in PNG format, click here. For the time being, this is the most extreme lossy compression option accessible for free.
The core EWWW Image Optimizer plugin is available for free and unrestricted use.
To be clear, paying is entirely optional.
Connect to the cloud optimization service for compression, CDN, and so forth.
Unlock all compression methods as well as a few extras.
Compression plans are extremely cheap, costing about $0.003 per picture. The cost to compress 3,000 pictures, for example, is $ 9.
The CDN plan, on the other hand, costs an additional $9 per month.
Optimole is a WordPress image optimization plugin filled with loads of new features to enable you fully automate all your image optimization needs.
Installing and activating the plugin is all that’s required. You won’t have to be concerned about slow site performance due to large picture files.
Test for Image Optimisation using Optimizol
When it came to compressing JPG and PNG pictures, Optimole delivered.
It decreased the file size of the JPG by 45 percent, from 484 KB to 217.8 KB. Compression is accomplished in two ways: one is lossy, the other is lossless.
Using both lossy and lossless compression, it was able to reduce the size of the PNG picture by 55 percent.
Advantages of Optimole
A unique feature of Optimole is its support for dynamic image serving, which replaces all your image URLs with cloud-based ones.
The Optimole server will now deliver all of your website’s optimized pictures when a user visits it. Your users will have access to photos of the highest quality, which will be dynamically scaled and fine-tuned to fit their unique viewport.
This method greatly speeds up the loading process and allows you to fully optimize your photos for all devices at the same time. You may also set it to reduce the image quality if the user is using a slower connection, just to be safe.
Is There Anything Bad with Optimole?
The major problem with Optimole is that it does not keep any of the resized and compressed pictures in your WordPress database. In real time, they are created and sent.
As a result, you have no access to the optimized photos and can’t use them anywhere else.
When using the free version of Optimole, your pictures will be optimized to receive about 5,000 unique monthly visitors. This is plenty for a newbie blogger.
And if your blog or website becomes popular, you may quickly upgrade to one of their premium plans.
the price of optimoles
Pricing starts at $22.52/month for image optimization for up to 25,000 monthly views and goes all the way up to $432.62 for websites with 3 million monthly visits.
If you’re just getting started with a WordPress website or blog, it makes sense to use Optimole because you’ll only get a little amount of traffic.
If your monthly traffic is fewer than 5000 visitors, you can send optimized pictures for free. The plugin is also ideal for users who want to eliminate the hassle of picture optimization by automating the process entirely.
However, if you need access to your optimized pictures, we recommend using one of the other plugins on this list.
The WordPress plugin version of the popular Kraken.io image optimizer, Kraken, is available for download. For the record, I utilize the Kraken.io web interface to optimize photos for client sites.
It’s a great, straightforward choice, however it’s missing some more complex capabilities seen in other plugins. For example, there is no support for WebP images.
Utilizes the Kraken.io compression service.
Compression techniques that use both lossy and lossless approaches.
Image resizing to a maximum size can be automated.
The chroma subsampling technique and the JPEG quality level can be selected manually.
Select the best-performing thumbnails from the ones you have.
Preserve the information that’s contained in an image’s EXIF data.
To begin, you’ll need to create a Kraken API key and link it to your website.
From there, you’ll be sent to a single options page where you may select the optimization technique to apply and:
Whether pictures should be optimized automatically upon upload.
Image scaling and resizing is performed automatically.
Which of the thumbnails should be improved?
Whether or not to keep EXIF data.
In terms of pricing, Kraken provides you with an initial 100 MB credit as a no-cost bonus. After that, plans start at $5 a month for up to 500 MB of pictures and go more expensive from there.
Uploaded media files are automatically compressed by Optimus. Size reductions of up to 70% are achievable depending on the image and the format. These savings help the blog page operate better by saving a few kilobytes each image. The most amazing aspect of the compression method is that the image quality is not compromised.
WHAT IS THE PROCESS?
While the photos are being uploaded to a media library, the Optimus plugin simultaneously transmits them to the Optimus server, where they are processed and delivered back in an optimal format. In the end, the Optimus plugin compresses the image and saves it in the media library in less file size.
Optimizing pictures, including thumbnails, is done invisibly, behind the user’s back and without their knowledge. Optimus’ media library displays picture compression improvements as a percentage value for each file, as shown in the screenshot.
Image files can be purged of extraneous data that image processing applications save but isn’t required to view the image. Graphene quality is preserved but the overall picture size is drastically decreased. If you want, Optimus can preserve the original photo’s creator, EXIF, and copyright information, resulting in smaller compressional benefits.
