Image Optimization WordPress Plugins

When it comes to website’s speed, images are the most important factor behind website loading time and Image Optimization helps to reduce webpage loading time. Google and other search engines give high preference to web pages that are highly optimized for speed.

As a larger number of people have started to use mobile and tablets to browse websites, users hate to wait for websites which take more time to load. Based on current technology trend, it’s better to enhance loading time of website before you lose your customers.

Best Image Optimization Plugin for WordPress

And hence, it has become a top priority to compress image on your website to speed up and rank your site higher in search engines. There are other excellent articles and plugins for enhancing your WordPress images experience too.

Images are the most important factor behind website load time as they are good for explaining things quickly and can also be used as a content enhancer.

High-resolution images that are unnecessarily large in file size can drastically slow down page speed. Why waste resources and time when it’s possible to reduce image size without losing it’s quality?

However, having lots of images in your content can slow down the loading speed of your web page considerably. A slow loading website will make you lose your customers.

So, it becomes very critical to optimize images on your website to make sure that your website loads fast for your visitors, and you can achieve higher search engine rankings.

WordPress Image Optimization Tool

Today I am going to tell some of the fantastic WordPress plugins that you can use to optimize images on your website and to enhance the overall loading speed of your website.

1. WP Smush

WP Smush

Let’s kick off this list with WP Smush, which is easily the fastest, most user-friendly and best-performing image compression plugin for WordPress.

WP Smush lets you compress JPEG, GIF and PNG images up to 32MB individually or in bulk using our dedicated smushing servers.

The plugin work by stripping meta data from JPEG files, optimizing JPEG compression, converting certain GIFs to indexed PNGs and stripping the un-used colors from indexed images.

With WP Smush, you can set up automated smushing so all of your new images are automatically compressed when uploaded to your site. WP Smush is also compatible with NextGEN Gallery and WP Retina 2x for high quality image display with the smallest possible file size.

Still not convinced? Site performance tool GTmetrix.com recommends WP Smush as one of its default optimization tips for WordPress sites.

2. ShortPixel

ShortPixel

ShortPixel plugin is simple to use which comes with a clean interface and useful features. You need to subscribe to ShortPixel to get the API Key and get the plugin going.

Upon subscription, you receive 100 free credits/month. While it isn’t as many as those offered by TinyPNG they should be enough for the average WP blogger. Also, this plugin only counts the images they succeeded optimizing by at least 5%. Otherwise, no credits are charged.

What I felt is missing in the plugin – an option to keep EXIF data in images. Some (photographers mainly) could find this feature very useful.

The plugin also offers a backup and restore solution for the optimized images.

3. EWWW Image Optimizer

EWWW Image Optimizer

EWWW Image Optimizer automatically and losslessly optimizes your images as you upload them to your site. It can also optimize images that you have previously uploaded.

Another nice feature of this plugin is the ability to convert your images to the file format that produces the smallest image size. It can also optionally apply lossy reductions for PNG images.

4. CW Image Optimizer

CW Image Optimizer

CW Image Optimizer is another plugin that automatically and losslessly optimizes your images as you upload them to your site, and can optimize images previously uploaded.

This plugin is based on WP Smush.it, though unlike the WPMU DEV plugin which uses the Yahoo! Inc. Smush.it service, CW Image Optimizer uses the Linux little utils image optimization tools. This means your images never leave your server.

Installing littleutils can be fiddly so this plugin it’s for noobs – it’s easier to install any of the other standalone plugins in this list.

5. Compress JPEG & PNG

Compress JPEG & PNG

What I like about TinyPNG is that they have the option to optimize only certain image sizes, they offer the option to resize the original image (it can lead to great savings), and they have a generous free monthly plan (500 images/month for free).

They didn’t offer any backup option, the optimization results are in KB/MB (it is rather confusing), and there is only the option to optimize the images as lossy.

6. Imsanity

Imsanity

Don’t be scared off by Imsanity’s freaky feature image in the WordPress Plugin Repository. This free plugin automatically resizes images to a more “sane” size.

A nice feature of Imsanity is the ability to set a maximum width, height and quality. You can also convert BMP files to JPG so images can be scaled.

7. Hammy

Hammy

If you take adaptive design seriously, you might want to consider using Hammy. This plugin takes your images and regenerates a number of smaller sized images. So when a visitors arrives on yours site, they see the most appropriate sized image (or the smallest one possible). This makes for a better and faster experience, especially for mobile users.

Hammy only works for images within posts and pages, not custom post types.

8. SEO Friendly Images

SEO Friendly Images

SEO Friendly Images edits all your images with proper ALT and TITLE attributes to help boost your SEO. If your images don’t have ALT and TITLE already set, this plugins adds them in according to the options you set.

Is it worth using ALT and TITLE attributes? Well, yes. The ALT attribute describes your images to search engines, while TITLE automatically appears in the tooltip when a user hovers over an image.

9. PB Responsive Images

PB Responsive Images

PB Responsive Images automatically reformats all your images into a format similar to the picture tag proposed by the Responsive Images Community Group on w3.org.

Each image is reformatted based on standard CSS media queries and SLIR query pairs, giving more flexibility in the variety of query combinations. Also, the plugin provides shortcodes so you can customize the queries used per image, and helper functions that can be used to customize the queries used per post or per layout.

10. Media File Renamer

Media File Renamer

Media File Renamer allows you to rename your media files by updating their titles. It also automatically updates their links in posts.

Search engines like Google give a lot of importance to file names so it’s important to be descriptive and use appropriate keywords to improve the SEO of your images.

11. Lazy Load

Lazy Load

Let’s not leave lazy load plugins off this list. Lazy load doesn’t need configuring because it works out-of-the-box.

It uses jQuery.sonar to only load an image when it’s visible above fold. This plugin is an amalgamation of code written by the WordPress.com VIP team at Automattic, the TechCrunch 2011 Redesign team, and Jake Goldman from WordPress consultancy 10up.

12. BJ Lazy Load

BJ Lazy Load

BJ Lazy Load allows you to lazy load selected images, including post images and thumbnails, Gravatar images and iFrames, and replace content with a placeholder.

Unlike Lazy Load, there are some simple settings that allow you to customize how the plugin works, such as choosing a placeholder and skipping images with classes.

This 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).

13. Bulk Resize Media

Bulk Resize Media

WordPress allows you to upload heavy images but its not good for your server and load time of your website.

This plugin automatically resizes huge images and makes sure maximum upload size is respected for all uploaded images. The plugin also works with multi site to allow admins to control the image uploads.

This plugin optionally converts BMP images into jpgs.

It also bulk resizes all existing images for better performance. You can also set max height/width and jpg quality.
