Time to concentrate on the website speed to grow your rankings as along with Google, others search engines also consider user experience as one of the biggest factor in rankings.
How Images Slow down a Website
There are several reason why and how heavy images slow down the website to load. Let me break this down in few points.
The three main reasons why images can slow sow your WordPress site are and how to get over it.
- If you are using too large images – Certainly, too large images increases the page size and will slow the website.
- If you are using too many images – Every image requests makes HTTP requests and when a page make multiple HTTP requests, resulting a slow page. Although, in this case, incorporating content deliver network (CDN) will make sense.
To make the site faster you should get rid of such things and monitor and maintain the site wisely.
Manual Ways: Optimize Images Before Uploading to WordPress
Since now you know the important of image optimization of your website. Let’s hop into and see what are the manual ways to optimize the images to keep it lighter loading wise.
1. Choose Right Image File Formats
Now you know the image file formats has also a lot to do with the file size of the image. For instance, if the same image saved in multiple formats like jpg, png or WebP will result different file size. Yes it does.
Now, you might be wondering which image format to use to keep the page size smaller and help to its best in compression. Dramatically the answer could not be specific to particular format. Let me describe the scenarios when you can use a particular format according your type of content.
JPG (Joint Photographic Expert Group)
This is the most commonly use file format around the globe. Most of the folks like photographers or even bloggers use this format for their content. Because this format is quite Lossy and using compression technique could bring the file size down a lot. Probably that’s why its quite popular since it uses millions of colors and suitable for photographs. The down side is if the compression is not done properly, you will loose the image quality.
PNG (Portable Network Graphics)
It’s one of my favorite, according to my content of course. Since I use a lot of vectors graphics, illustrations and icons being a web designer. It is lossless image format. That means after compression the image (.png format), you might not find drastic changes to the file size. You might be thinking, then why should one use PNG’s. That’s because it lets you keep a transparent background which are used in plenty of scenarios, text, logos, icons and vectors where you don’t need the background.
WebP (Web Picture)
Comparatively to jpg and PNG, WebP is extremely new image format. In fact this image format is getting too popular, since it brings a lot of different in the file size without loosing the image quality at all. Although, since its quite new so probably still few browsers might not support it apart from the popular browsers. By the way so far till 2021, 94% of the browsers supports webP and being introduced by google. Google claims, it will reduce 34% of file size compared to jpg and 26% smaller than PNG image format. Both lossy and lossless are allowed by WebP image format.
Are you in a dilemma which image format you should go with. Well, it depends on the requirements. You can use multiple format on your web page in different scenario. But certainly future is WebP as it helps to minimize the image sizes dramatically once you convert other formats into it.
2. Use Correct Image Size
You need to deliver the scaled images in order to further optimize your images in WordPress. You might be thinking, what would be the correct image size file for your content or blog layout. And how can you determine it.
Its one of the important point to consider and rescale your images according to your content width. Because, if you place bigger resolution image in the smaller layout, then while loading the same image by the user the browsers need to scale the image to display pixel perfect. Which certainly takes extra time to loading, resulting slow loading page.
There are several image resizing tools available both online and offline. These can be use to resize the images before uploading to WordPress.
- Online tools – Reduce images
- Offline tools – Adobe photoshop, GIMP etc.
I generally use photoshop, the process is simple.
Open the photo in photoshop. Press Ctrl+Shift+I from your keyboard. Image size dialog box will pop-up.
Input width parameters according to the requirement. The height of the image will also proportionately.
Resizing is crucial, if we are in the process of optimizing the images before uploading. There are several other things to do as well to keep the website lighter and optimal.
3. Compression Your Images
The process followed to minimize the size of an image file, whether it could be the resolution or pixels without effecting the quality is called image compression.
optimized images goes 40% lighter than the unoptimized images. doesn’t matter before or after uploading, image compression needs to be done compulsory to make the website load faster and optimal.
Now, its completely depends which kind of compressions you would like to go with loosy or Lossless as explained on JPG’s and PNG’s.
4. Think About the Featured Image
WordPress posts don’t contain featured images, but the images are used structurally throughout your theme. When viewing a particular post, for instance, it may appear as a thumbnail next to the title.
You can’t afford to ignore optimizing the featured images because many themes and widgets rely on them. Although, featured images looks good and it is possible to use featured images to set custom header images on specific posts and pages or to display thumbnails. But, it impacts slowing down your website to some extent.
Decide the size of your featured image once according to your layout, and this size will apply to all future featured images. I prefer not to display the featured image for single posts for few of my blogs, which helps loading a bit faster.
5. Apply Lazy Load Images
Typically whenever you visit a web page, all the content along with the images will get started loading. And that would certainly, takes time. Moreover if you have a heavy page with tons of image, that might look like a disaster.
This is where lazy loading images feature will be the ultimate rescue. activating this feature will let the images to load one by one, only if the user scrolls down.
6. Cache Images
At most every website follows this process of caching images for their website. The process helps the end user to load the website or web page faster since the images get saved with the help of browsers in local or a near by server.
The process can be followed through copy or installing any one of the popular caching plugins or any image compression plugin like WP Smush.
7. Need to Avoid Image URL Redirects
Another factor that may cause a slowed down page is the redirects created by your images. Redirects usually occur when images link to other places.
Embedding images from outside sources onto your website is not recommended. As a replacement, save each image and media piece directly to your site. Make sure your images do not link out to anything, such as a separate media page.
8. EXIF Data Need to be Removed
An image’s EXIF data contains information about the location and method of taking the photo. For web files, it isn’t usually necessary since it is automatically added by cameras.
Thus, eliminating this data from your images could improve the performance of your pages, although it will not have a major impact. There are a few plugins available in the WordPress repository that might help you get rid of it. It’s recommended if you use a lot of photographs on your website.
9. Content Delivery Network (CDN)
Although, it’s not at optimization technique, but definitely would help your site load faster to the users. When we have a group of servers located in several areas around the globe and the content can be delivered from the closer location to the users, is referred as Content deliver network (CDN).
Using CDN is one of the faster way to serve the users with the content as fast as possible. There are several CDN services available in the market FREE and Paid both.
