Perhaps you’re looking for the best free image optimization plugin WordPress. Nowadays, images are the most critical aspect of SEO and are required for all websites. Unfortunately, one of the most common causes of slow websites is images.
There are still multiple explanations for adding images to your WordPress content. The visitors will be more engaged if you are using graphics. It can also separate lengthy parts of the content and benefit from SEO.
Multimedia is an essential element of every content marketing strategy. A slow webpage, on the other hand, is an issue because it can drive away visitors.
In actuality, websites take a few seconds to load, and the possibility of a user leaving is higher than usual, so your bounce rates grow.
However, many factors can slow down your website; images and videos are the most critical elements. For a free speed solution for your WordPress website, check out my article on speed optimization plugins.
WordPress Image Compression
WordPress image compression uses various approaches to reduce requests, including resizing, compressing, caching, and lazy loading. Do you have any ideas? On most websites, images take up more than 50% of all bandwidth.
Still, not all plugins are required at the very same time. I’ll review some of the significant factors of choosing a WordPress image optimizer plugin free. Here are some considerations for optimizing WordPress image speed.
It can deliver different-sized images depending on the resolution of the devices. This helps you improve the website’s overall performance by optimizing images.
Mobile devices need to serve images through adjusted images. You’ll find resized image issues if you run GTmetrix testing on your site from a mobile phone.
Serve Images in Next-Gen Formats (WebP)
Next-generation image technologies offer better quality and savings than JPG or PNG. In some conditions, WebP can replace JPG, PNG, and GIF.
It enables lossy and lossless encoding. WebP is a Google-developed format that significantly reduces the size of the images on the website. Converting images to the WebP format includes lightweight encoding and decoding.
In fact, WebP is used on YouTube. Chrome, Firefox, Edge, Opera, and Safari have recently been introduced, and many other browsers support WebP properly. The WordPress WebP Converter for Media plugin is a better option; it is also free and straightforward.
You can also use the WebP format to directly upload your media library. This is advantageous because it avoids the need for extra plugins; as a note, plugins always slow down a website.
AVIF File Format
Compared to WebP, JPG, and PNG, AVIF is compatible with high-definition images. It fully supports the produces smaller files while utilizing HDR. It also includes some of the most cutting-edge graphic technology. AVIF is a fast-growing image format. Likely, it will eventually get full support across all platforms.
Defer Offscreen Images
A few PageSpeed and GTmetrix suggestions are to “defer offscreen images.” When the browser needs to load critical resources, such as graphics below the fold, the page takes longer, and visitors cannot interact with the page as fast as they would like.
Deferring offscreen images can help your WordPress website perform better in key metrics like first input delay and page load time.
Properly Size Images (Dimensions)
Another critical issue with images is that you need to resize huge images to smaller ratios to avoid “properly size images.” in page speed errors and GTMetrix. If you’ve previously uploaded extensive images, you’ll need to resize them manually or use a plugin.
Large file size images with large dimensions mean the browser must adapt the graphic to the site layout. It is OK to scale your images correctly. Still, the browser must download additional data when providing images at their highest screen resolution.
Efficiently Encode Images
“Efficiently encode images,” which indicates that you should compress images. Using software like Photoshop, you can reduce the compression level to around 85% of the average level.
By reducing images with an optimization plugin and delivering them through a CDN, you can get a solution for efficiently encoding images.
How to remove EXIF image data?
“Removing EXIF data” means removing unnecessary data from images, such as size, names, depth of field, brand, time, and others. Avoid graphics embedded from other websites; they must be uploaded to your own.
Meanwhile, it’s not hosted on your website but comes from an external source. You’ll get a bunch of additional requests, significantly slowing down your performance. Most WordPress Image Optimizer Plugin Free includes removing EXIF data.
WordPress Image Optimizer Plugin Free
In this section, I’ll show you how to choose a WordPress image optimizer plugin free. You can pick up a suitable plugin with these recommendations. Still, don’t use too many plugins to do the same task.
1. WebP Converter for Media
WebP Converter for Media is a plugin for WordPress that is free and straightforward. As a result, you can automatically use this plugin to display WebP for your website’s new and current images. Currently, this plugin supports images, gifs, jpegs, and png.
You can select image files from specific folders to convert to WebP format. However, use this plugin; you have some requirements.
- You’ll need PHP 7.0 or higher and the GD or Imagick modules.
- The module must support WebP and native PHP, which WordPress uses to deliver images.
- “Mod mime,” “mod-rewrite,” and “mod expires” must all be configured on your server.
Before switching to WebP formats, you can adjust the image quality using the Quality feature. Set the rate to the recommended parameters for best results.
WebP images will take up more space if you increase the quality higher than recommended. Suppose you drop the quality below what is recommended.
In that case, the image size will be reduced, and the quality will also decrease. You suppose to have correctly configured the plugin’s features. It will then convert all your images to WebP format in the media library.
However, consider your website previously included many photos. In that case, you’ll need to select “Regenerate Images” to convert all the images at once.
If you deactivate or uninstall the plugin, your site will stop delivering WebP images. They will also be removed from the upload folder. Save a copy of all the photos before deleting the plugin.
2. WPvivid Image Optimization
WPvivid Optimization Plugin is the best free image optimization plugin WordPress. It allows you to compress images on your website effortlessly. That helps reduce loading times, improve user experience, and improve Google and GTmetrix scores.
You can use free image optimization for up to 2000 images or compress up to 5 gigabytes per month. Also, the plugin allows you to lazy load.
With a single click, you can optimize all of your images in a batch and resize your existing photos in bulk or manually.

|WPvivid Image Optimization Cons|
|– WebP is not supported in the free version.|
– Compression Level is not in the free version
– You are limited to 2000 images
– Maximum file size of 5MB
3. WP Smush
WP Smush from WPMU DEV is a popular WordPress image compression plugin. But the free version’s features are so limited. You can’t access the free version with auto-convert, lazy loading, properly sized images, WebP support, or backup.
It is a straightforward method for beginners to compress their images and increase the speed of websites. All your pictures will be compressed up to 5MB in length for free—the process with PNG, JPEG, and GIF files.
However, the free version has notable features such as Bulk Optimize, which lets you compress up to 50 images. You can detect and compress the images even if they aren’t in the media library.
Of course, Smush is very popular, but I despise this plugin because it gives users very little control over an image that is compressed. It isn’t the best option because it reduces the image quality.
|WP Smush Pros|
|1. Bulk Smush compresses up to 50 images.|
2. Smush is straightforward to use.
3. An improper-size image detector is included.
4. Image resizing with max width and height.
5. You can optimize images, even those not located in the media library.
|WP Smush Cons|
|1. No WebP support in the free version|
2. Only lossless compression
3. There isn’t enough compression and flexibility
4. No backup original pictures in the free version
5. Bulk Optimize is only up to 50 images at a time.
4. EWWW Image Optimizer
EWWW Image Optimizer is another popular plugin with fine features. Still, I am not satisfied with its image quality after compression. That plugin has been installed on almost one million websites. So that means it isn’t so bad.
It improves page load by optimizing images and is the free image optimization plugin for WordPress. You can optimize images you’ve already posted and choose the image resolution before compression.
It even provides unlimited files and has no frequency limitations. It includes auto-optimization and an image backup facility. Your existing files are saved for an estimated 30 days, and access backups anytime within a month.
My favorite feature is that optimization can be scheduled in the backend using the plugin’s configuration. Bulk optimization is also my favorite option; with a single tap, you can optimize all of your shots.
All CDNs, such as Cloudflare, KeyCDN, Fastly, and Bunny, operate quickly with bulk CDN. Also, you can clear the cache after a bulk optimization.
EWWW IO is compatible with all themes, plugins, and site builders. This plugin solves image errors, such as properly sized images, serving images in next-gen, deferring off-screen, and specifying image dimension errors in GTmetrix.
The EWWW Image Optimizer increases website page load speed. It helps you save storage space while reducing the overall load on your website. I already mentioned that graphics are the most common reason for a slow website.
For a better user experience, compress your photos with EWWW for faster loading times and better SEO.
|EWWW IO Pros|
|1. No limitations to compress|
2. Bulk Optimization
3. The free edition has a lot of features.
4. Vast image formats (JPG, PNG, GIF, WebP)
|EWWW IO Cons|
|1. No option to modify the compression mode|
2. Image quality is terrible after compression.
2. Many negative reviews about the crash
3. The free version misses significant features (Auto-Scale, Auto-WebP).
5. ShortPixel Image Optimizer
ShortPixel is one of the most well-known plugins, with over 300K installations. The free version is fully functional, but you can only compress 100 images monthly. So I’ll just be concerned with the free version and skip the paid version.
It exists in a range of compressed levels. So you can choose from lossless, lossy, or glossy. ShortPixel follows the same basic approach as some other cloud-based image optimization.
The plugin automatically delivers the images to the cloud and stores them in the Media folder, overriding all previous ones. All original photos are automatically saved in a backup, which can be restored quickly and separately in the collection.
You have the possibility of keeping the original version. You can also use one API key to run the ShortPixel plugin on multiple websites.
Furthermore, the plugins have full Cloudflare integration. You can compress JPG, PNG, and GIF images and PDF documents. All PNGs are converted to JPEG, significantly reducing the file size, notably if you have camera photographs.
ShortPixel is an excellent solution for most image issues in WordPress. Still, to access all of the features, you’ll need to upgrade to the pro version.
The free edition is ideal if you run a website with relatively little traffic. However, your website receives a lot of traffic, which isn’t enough.
|1. Choose between lossless, lossy, or glossy|
2. Backup for all original images in a separate folder
3. Automatically convert the PNG images to JPEG
4. Optimize Media Library after upload
5. Bulk optimization for 100 images in the free version.
|1. Each month, only 100 images are available for free|
2. The free version has a lot of limitations
3. It isn’t an exact lightweight plugin.
Optimole is a multi-functional image optimization plugin. It allows you to gather your large images on the cloud and enhance your images in real-time. It enables you to speed up your website by ensuring the proper image size for every device.
The plugin is available in many plans, such as free, personal, business, and custom. But first, let’s gab about the free plan.
You can enhance images for only 5,000 monthly visits with the free version. Yeah, it is suitable for a low-traffic website, but others need to move to pro versions like ShortPixel.
Optimole has excellent features such as images that will auto-optimize and adapt to all devices separately, improving the performance and UX.
I like this feature, which reduces image quality for visitors with slow internet connections. Also, Optimole delivered images via AWS CDN.
It offers control statistics showing the total bandwidth and the server’s storage. Optimole allows you to customize the betterment of your images. You can add a personal watermark to images to prevent them from stealing.
|1. Serve WebP images|
2. The image size is suited to the device
3. Smart Cropping is available.
4. Optimole does not use jQuery or other weighty JS.
|1. The free version has several limitations.|
2. You can only serve images for 5,000 monthly visits.
7. Rocket Lazy Load
First, you need to know this is a lazy load plugin for images, video, and iframes. Rocket Lazy Load is not an optimization or compression plugin. It is WordPress Image Optimizer Plugin Free.
My favorite feature of this plugin, which comes from WP Rocket, is “Replace Youtube videos by thumbnail.” It is a unique feature if you use Youtube for your website.
Using YouTube videos for your content is beneficial but seriously impacts the site’s performance. But it is no longer an issue with Rocket Lazy Load; it is just an image format.
Its lazy load works fine, but some key features are lacking, such as the option to exclude some images from the lazy load; you can do this yourself, but not with the plugin feature.
“Lazy loading” is a code that delays downloading pictures not displayed to users. The images will load when you come into view.
|Lazy Load Pros|
|1. Rocket Lazy Load is entirely free.|
2. You can lazy load all the images on your website.
3. For your YouTube video, use Replace Thumbnail

Imagify is a practical image compression toolkit. That lets you accelerate your WordPress website by using lightweight shots while keeping the image quality.
Imagify offers a free plan and multiple premium options. The feature is the same in both versions; the only difference is the number of images you can optimize.

3. For beginners, setup may be complex.
9. reSmush.it WordPress Image Optimizer Plugin Free
One significant benefit is that reSmush can compress unlimited images per route. Simply click the optimize tab, wait for it to finish, and your pictures will be minimized.
The main disadvantage is that there are no different compression levels offered. This plugin has no advanced features, yet, it does support JPG, PNG, and GIF images, although it does not support WebP images, which is a big downside.
The plugin is free; the only limitation is transferring images below 5MB, which is suitable for blogs and content-focused websites. Users can choose the compression level for each upload using the reSmush Web service.

How do we forget about TinyPNG when it comes to image optimization? A helpful image compression tool also has a WordPress plugin.
It can work with PNG, WebP, and JPG files and significantly reduce the image size. TinyPNG is not a totally free tool. You can free optimize up to 100 images per month.
It’s simple because it integrates well with WordPress and keeps pixel density when compressing PNGs. TinyPNG reduces images using external cloud integration, and after analysis, the best method is used for each image.
Existing JPEG, PNG, and WebP photos can be batch optimized. The original image is replaced with a smaller version with no noticeable quality loss.

WebP versions, which are part of ideal image solutions, can do many things. And you can activate features or use WebP to replace JPG or PNG files. Also, remember that new WEBP files have additional storage. But, if you don’t want to, you can remove it.
Let’s say a browser that doesn’t support WebP images. In that case, LSCache will provide the original image format. There are other options in that part, but I won’t go over them in this discussion.
12. WebP Express
WebP Express includes an integrated tool for converting images in various ways with the WebP. On browsers that support WebP, (.htaccess) rules for WebP generation, which allow for separate image outputs for a jpeg and a png, will result in a WebP.
You can automatically serve Webp images to browsers that accept them without difficulty. While still serving JPEG and PNG files to users, Webp doesn’t support them.
This plugin uses Imagick, CWebp, VIPs, and GD modules to convert images to Webp. The converted images are typically half the size while retaining the same quality.
13. A3 Lazy Load
A3 Lazy Load is a simple-to-use that speeds page load time by lazy loading images, videos, and iframes. A3 Lazy Load is a significant advantage because it is simple to customize even if you do not know it.

Conclusions: WordPress Image Compression
So it’s time to end my long content about all these matters. This explanation guide was created to help you learn the core aspects of image optimization for those looking for WordPress image compression.
Images improve the readability of articles or any content. It also enhances audience attention and builds the tone and uniqueness of your webpage. Putting graphics into content can help you advance your site effectively.
However, when you’re not attentive, images can take up over half of the overall space of a website, maybe even more. Not all readers can have full internet speeds.
As a result, page clutter and slow page loading times might negatively affect overall SEO ranking. It would help if you got into the routine of optimizing your graphics today to help them reduce the loading time.
Give priority to the sizes and adjust those, such as large graphics and camera images, because they are lengthy and huge, so you need to resize them to a more acceptable size.
Also, you can try Photoshop and tools like TinyPNG and CloudConvert, or the best free image optimization plugin for WordPress.
