Without images, most websites would look like a massive wall of text. To capture the visitor’s attention, high-quality images are a must-have. They will break up your content and make it more readable. Not to mention the extra traffic from image searches. But to have all those benefits, images need to be optimized properly first.
Most WordPress site owners end up uploading and using images that aren’t optimized for the web, which can cause a lot more harm than good.
Below you’ll learn why optimizing your images is a must, and learn five ways you can optimize images for WordPress.
Failing to optimize your images will lead to incredibly slow loading speeds and bandwidth issues. Images can take up a considerable amount of space, and most of it is unnecessary.
Here are some of the main reasons to optimize images:
A slow loading site creates a poor user experience. This leads to higher bounce rates and less time spent on your site overall. You can’t expect your users to stick around and wait for your images to load.
Usually, you won’t hit the storage limits of your current web host.
But, having a site that takes up less server space will make it more nimble.
You can reduce the bloat of your website and have a leaner and higher performing website. Plus, you can reduce server costs if you’re paying based upon storage.
Google and other search engines hate slow loading websites.
By optimizing your images your performance will improve, and so will your rankings.
With optimized images, Google will crawl and rank your images much faster too, which can be a nice boost in traffic.
Optimizing your images doesn’t have to be difficult or time-consuming, and can become part of your regular posting workflow. Failing to optimize your images can be damaging to the success of your site.
Below you’ll learn how you can optimize your images for WordPress in a way that retains the quality and doesn’t sacrifice performance.
Your goal with image optimization is to reduce the file size without sacrificing the image quality. There is no perfect way to optimize, but instead, it’s a balance you’ll have to strike.
There are many approaches you can take to optimize your images. You can even combine a couple methods to ensure your image file size is as low as possible.
Keep reading to learn five different methods you can use to easily optimize your images to the web.
Before you even start optimizing make sure you’ve chosen the right file format. The file format you choose will affect its total size, and ability to optimize the image.
The two most common image types are JPEG and PNG.
JPEGs are commonly used for photographs and general images, as they:
PNGs are used for vectors, logos, screenshots, and smaller images. Since it has a larger file size, you’ll want to use these less often.
Aside from PNG and JPEG, you’ll find dozens of other image types. But, they aren’t recommended when creating images for the web.
But, there is an exception. You’ve probably noticed the explosion of GIFs in recent years. These little-animated videos can be used to enhance your existing content. If you’re planning on inserting a small video, make sure it’s in GIF format, and not MP4.
When compressing an image you’ll need to find the balance between the compression quality and the size of the image.
With minimal compression, you’ll end up with a larger file size, but a higher quality image. With a high level of compression, the image size will be very small, but the image quality will suffer.
Your goal should be to find a happy medium between the file size and the level of compression you use.
If you run a website that relies on high-quality images, like a photography site, then it’ll take more time to find the balance between the two. But, you’ll be able to use the optimization settings for every image moving forward.
Below we examine desktop-based tools, web-based tools, and even a few WordPress plugins you can use to compress your images without sacrificing quality.
Desktop-based tools offer you more control over your optimization settings. If you’re used to working in a photo editor like Photoshop, then you might prefer this approach.
Some of the most popular desktop-based tools include:
The above tools have a bit of a learning curve, but they allow you to find the image optimization settings that work best for your needs.
If you prefer a more simplistic approach, then you can use an online tool that automatically optimizes your photos.
These tools are great if you don’t want to spend time learning the ins and outs of photo editing software.
With these all you have to do is upload your photos, the tool will run, and you’ll download your optimized photos.
Like most things WordPress, there’s a plugin for every problem you come across.
The following plugins will optimize your images as you upload, and even optimize any images already in your media library:
Before you begin optimizing your images it can be helpful to size them properly. There’s no point in uploading a massive image to your site, especially when it’s going to be resized anyway.
Get your image dimensions correct before you upload. That way you’ll be dealing with a smaller image from the start.
For example, let’s say you need a 300×300 pixel image, but instead, you upload a 3000×3000 pixel image and make your WordPress theme shrink the image to display properly.
This will not only increase your bandwidth, but it’ll make your photo load very slowly.
The best approach is to take note of the image dimensions required by your theme and size your images accordingly. Then, run it through an optimization tool and upload your image.
WordPress has a built-in image editor that lets you crop your images from your dashboard.
Although this can be useful, we recommend cropping your images before you optimize and upload them.
If you realize an image needs to be cropped to better fit your site, then delete the image from your site, crop it, and re-upload it.
By performing too many edits within the dashboard you can end up saving multiple versions of the same file. This increases your server load and the overall size of your site.
Did you know that you can optimize your images to help your site and images rank in the search engines?
Optimizing your images will speed up your site and improve your chances of ranking. But, there are a few additional steps you can take to improve your image SEO as well.
Follow the steps below to improve the SEO of your images:
The image title text will appear when a reader hovers over your image. It’s not super important for SEO, but this little trick can improve your user experience.
To change your image title text navigate to your post editor where you’ve placed an image.
Hover over the image and click the pencil icon, which will bring up the ‘Edit’ option.
On the ‘Advanced Options’ screen you’ll have a place where you can enter or change your image title.
The alt text of your image will give Google an indicator of what your page is about.
If you have multiple images on your page, then the first image should include your target keyword. Every image that follows should use a variation of that phrase, while still being relevant to the image.
To change your image alt text navigate to your visual editor and hover over an image you’ve inserted. Once again, click on the pencil icon which will bring up the ‘Edit’ option.
On this screen look for a box labeled ‘Alternative Text’, and enter your focus keyword or related keyword into that box.
Your image filename can help it rank in Google image search, which can be a nice source of additional traffic.
Instead of having a nonsensical filename, change it to something that includes your target keyword or reflects what the image is about.
Before you upload the image to WordPress spend time considering what an appropriate name for that image would be.
Finally, if you’re using multiple words in your filename make sure you’re using a hyphen between your words, as Google will read them as a space. Otherwise, the words will run together and your filename won’t be readable.
Going through the steps above to optimize your images will make it easier for Google to love your site.
It’ll load faster, your visitors will thank you, and so will your search engine rankings.
When dealing with compression it’s important to play around with settings and different tools until you find the perfect balance of image quality and image file size. It’s a hard balance to strike, but one that’s worthwhile to your loading speeds and browsing experience.
