ImageKit – URL based image manipulation and optimization

by imagekit

Description

Images make up a critical part of all websites and mobile applications these days. They are the centerpieces of a great product and user experience. Managing your images and delivering the perfect image, tailored and optimized for your user’s device is, therefore, more critical than it has ever been. However, this takes up a lot of development and maintenance time that could have otherwise been used in building your core product. This is where ImageKit can excel.

This plugin will automatically update all the image URLs in your post so that images are fetched from ImageKit for optimization and faster delivery instead of your web server.

Faq

Do I have to register on ImageKit.io to use this module?

Yes, you need to create an account on https://imagekit.io first to use this plugin.

How does this plugin works?

This plugin changes the HTML content of the post to replace base URL with ImageKit endpoint so that images are loaded via ImageKit.

I installed the plugin but Google pagespeed insights is still showing image related warnings

This plugin automatically optimize the images and serve them in next-gen format including WebP. However, this plugin does not automatically resize the images as per the layout. WordPress 4.4 has added native support for responsive image. Learn more to make your themes image responsive.

Do I have to manually change the old posts to optimize their images?

No, this plugin automatically takes care of that.

Does this plugin support custom CNAME?

Yes, you can email developer@imagekit.io to configure custom CNAME for your account and then specify that in the plugin setting page.

Can I configure this plugin to use ImageKit for custom upload directories?

Yes, you can specify any number of custom directory locations on plugin settings page

Does ImageKit support all image formats?

ImageKit supports all popular image formats that cover 99.99% of the use case. On the settings page, you can further configure if you want to allow or disallow a particular file type to be loaded via ImageKit.

I installed the plugin, but the ImageKit website analyzer is suggesting more optimization.

This is because image dimensions are not as per the layout. We could have done it using Javascript in the frontend like other plugins, but we do not recommend it. The browser triggers the image load as soon as it sees an image URL in HTML and intentionally delaying this while Javascript calculates the ideal width will ultimately slow down the image load for your users. WordPress 4.4 has added native support for a responsive image. Learn more to make your themes image responsive.

Best free cdn images for wordpress etc.

Amazing Plugin But with a Small Shortcoming

By iSaumya (isaumya) on June 29, 2020

To be very honest I have used ImageKit before but this is the first time using it with WordPress and I must say the plugin works flawlessly. The only shortcoming of the plugin is that it doesn't replace the image URLs inside the CSS (like background images). Which was a big negative in my opinion. If I consider this plugin like a CDN plugin then both CDN Enabler (by KeyCDN) & W3 Total Cache CDN replaces image URL inside CSS files, inline CSS & internal CSS but for some reason, this plugin does not. So, if this plugin also provides that feature in future will definitely update my review to 5 stars and can wholeheartedly recommend this to all my WordPress clients.

Far better then other plugins

By skylinks on March 18, 2020

Honestly this is far far better then other over rated plugins , we have used some other plugins in past & most of these will trick you to buy premium packages but thats not the case with Imagekit these guys look pretty transparent with customers right now. everything is well explained & its pretty easy to configure.

Great service. Great plugin.

By dear.leader (llcodyson) on March 11, 2020

I've become a huge fan of Imagekit over the past year of using it. It's easy to get started with and more important for myself, it's highly configurable. At first I was a bit apprehensive when I saw Imagekit advertise the variety of sites and frameworks they integrate with because that often means that something like this WordPress plugin ends up poorly maintained or with incomplete functionality because resources are spread too thin. But this plugin's been rock solid since I've been using it. No bugs (that I've noticed) and it supports all the functionality and customization that the service provides. I suppose one exception is that there's no way to sync your WordPress media library images with Imagekit's media library, so I've had to handle that myself with their API. The only other thing I'd like to see improved with this plugin is the option to configure settings using constants in wp-config.php. I manage a multisite installation and have to manually configure the same settings on each site.

Easy to use

Really fantastic

By lvsh on June 6, 2019

After fumbling around with Cloudinary for hours (and unable in the end to get it to do what I wanted), I stumbled across ImageKit and gave it a try. Works right out of the box, just as they say. Could not be easier for a beginner to set up, and has everything anyone could want in terms of optimization and transformations.

Not Ready Yet

By Robert Neu (fatmedia) on September 14, 2017

This plugin and service sounds like it could be pretty cool, but unfortunately it's not ready for production environments yet. The plugin does not support custom wp-content directory locations and the way the rewrites work is fragile at best. Hopefully they're able to improve the plugin because the service looks pretty interesting!

Ultimate optimisation
