Using high-definition photographs and images for aesthetic reasons is great, but it may impact your websites speed. Luckily, WordPress image optimizer can prevent that from happening!
With mobile browsing finally overtaking desktop, users on those devices are not going to wait for websites which take more time to load. You must consider website loading speed before you start losing your potential customers.
Psst! Search engines give preference to web pages that are highly optimized for speed!
It takes less than five seconds for your visitor to close the page and leave because it was still loading. Haven’t we all been in that position? For that reason, we made this short image optimization tutorial that will help you improve your website’s performance.
Better image optimization, better loading time
Before we dive into the technical part, here are some of the benefits of image optimization:
- Faster loading speed,
- Improved Google PageSpeed score,
- Improved Search Engine rankings (Google, Yahoo, Bing, and others),
- More visitors and smaller bounce rate,
- Cuts the costs because you will need less storage on your servers,
- Smaller numbers on both your and your visitors’ mobile data plan.
Quick Lesson on Image Formats
If you want to be able to do some fancy WordPress image compression, you have to know the basics of image formats. Unless you have this covered, keep reading. The most common image formats are PNG (.png) and JPEG (.jpg).
The latter provides the best format for photos, images with gradients and images rich with colour, while the first is better with a smaller colour palette for logos and images with transparent backgrounds.
If you are trying to create an image with a size of 2MB or less, you might try to resize it. Here is how.
WordPress resize images tools
Well, for some the best WordPress image optimizer might be the one you can find in your Media Library. Click on the Media – Select your image – Edit image, and then pick new dimensions for your image.
While choosing the correct image format can save you some space, resizing the image itself can save even more. How much should you resize depends on your websites’ width and the container?
Sometimes adjusting the image to your website’s maximum width limit can reduce the image size from 3MB to 1MB!
There is another take on how to optimize images in WordPress, and that is through using the various plugins.
If you want to optimize images WordPress, reSmush.it is the right tool for you. This picture optimizer automatically compresses images on upload and it also allows you to enable bulk optimization for older images.
It is maybe the best WordPress image optimizer out there and it uses reSmush API to compress your images while it lets you pick the optimization level you find the best. However, keep in mind that it limits the optimization to the uploads smaller than 5MB. In case you need to add an image in full size, you can exclude that image from compression.
This WordPress image plugin is easy to use and comes with a simple interface and features, but you have to subscribe to get the API key and 100 free credits per month. The amount is enough for an average WordPress user.
The downside is that there is no option to keep the exchangeable image file format data in images, which might be a deal breaker for photographers.
This nearly free image optimizer allows you to optimize only certain image sizes, and to even resize the original image. The plugin offers you a more than generous free plan with a limit of 500 images per month.
The downside is that some pictures have blurry sections which are noticeable by a keen observer.
WP Smush.it runs in the background as soon as you install it. The plugin is easy to use as it automatically compresses all existing images and newly uploaded ones. There is a slight drop in quality, which is expected, but if you use WP Smush Pro – the change is hardly visible.
While we are at it, WP Smush Pro compresses the images by ten times their actual size, resulting in better website performance.
TinyPNG WordPress plugin is one of the easiest image compression tools for use. Simply upload the image, and in few seconds you will have the compressed result. With this WordPress image resizer you can upload up to 20 images with the size of 5MB or less.
This is another free image optimizer which you can use to upload up to 20 images. We recommend using the default compression to quality ratio setting. If you choose to push for more just change the setting and you are ready to go.
We are looking at possibly one of the best image compression tools. Compressor is free, easy to use, it offers two compressing options, and the quality of compressed images remains the same.
But you can only compress one image at the time, which is quite time-consuming if you have a lot of images.
This WordPress image plugin is a great way to optimize PNG, JPG, and GIF image files using its own API. The setup takes about a minute: signing up at Kraken.io homepage will provide you your API and secret keys.
Using the plugins default option, your images will be optimized using an “intelligent lossy” compression profile, resulting in a noticeable size saving without impacting the image quality. Of course, you can manually set a lossless option on the plugins settings page.
Now, Optimus is a great plugin focused more on performance than in tuning the details of the optimization, and it has a simple settings menu. The plugin can reduce the file size up to 70%, depending on the image and format. And the best thing is, Optimus keeps all the author, EXIF and copyright information!
But! The free version offers 100 KB file size cap which is quite underwhelming, and the plugin will not shot the compression details of each file, so you will have to do it manually.
Image compression WordPress is pretty simple with Imsanity. This plugin automatically optimizes images to the size of your choice; you can manually set the desired width, height, and quality. You can also convert BMP files to JPG so images can be scaled.
Media File Renamer is a little bit different from the other WordPress images plugins we talked about. To understand what it does, you have to know that the search engines give a lot of importance to the file names. It is all about the right keywords and SEO of your images.
Media File Renamer makes it possible to rename your images by uploading their titles while it also automatically updates their links in the posts.
The WP Rocket creators came up with a new plugin that is definitely worth checking out – Imagify.
You have to register to get access to this plugin and all its cool features but it is actually worth the trouble. You will get a bunch of useful options and modes for your image optimization.
Another useful feature is the option to have separate folders for the original images so you will be able to compare the originals to their compressed versions at any time.
BJ Lazy Load makes image optimization WordPress pretty simple. It allows you to load selected images and replace content with a placeholder. You can check out all the settings to customize the way it will work.
This WordPress image compression plugin caters to size-optimized images, automatically serves scaled down images in responsive designs, and automatically serving hiDPI images for hiDPI screens (like Apple’s retina display).
Image Pro makes it easy to upload, resize, and optimize images instantly. It is a solid WordPress image optimizer great for beginners because of how simple it is. All you have to do is simply drag and drop an image of your choice, post it, and the image will optimize itself.
