ImageKit.io: Image Optimization That Plugs Into Your Infrastructure

Celý článek

Images are the most efficient means to showcase a product or service on a website. They make up for most of the visual content on our website.

But, the more images a webpage has, the more bandwidth it consumes, affecting the page load speed - a raging factor having a significant impact on not just our search ranking, but also on our conversion rates.

Image optimization helps serve the right images and improve the page load time. A faster website has a positive impact on our user experience.

With image optimization becoming a standard practice for websites and apps, finding a service that offers the most competent features with a coherent pricing model, one that integrates seamlessly with the existing infrastructure and business needs, is paramount to any website and its efficiency.

So what are the most common criteria for selecting an image optimization tool?

The importance of image optimization isn’t up for debate, our choice of tool or service for it may just be. And it is a factor we should consider carefully. So where are the challenges?

• Inability to integrate with existing infrastructure - Image optimization is very fundamental on modern websites. To implement it, we should not have to make any changes to our existing setup. But unfortunately, a lot of these tools or services can only be used with specific CDNs or are incapable of being integrated with our existing image servers or storage.
• Dependency on their image storage - Some tools require us to move our images to their system, making us more dependent on them — an added hassle. And nobody wants to spend their time and effort on a virtually unnecessary step like migrating assets from one platform to another (and may be migrating to some other service in the future, if this one doesn’t work out). Not when it’s not needed. Not if we have hundreds of thousands of images and can never be sure if all the images have been migrated to the new tool or not.

Apart from the above challenges, it is possible that the choice of tool could be expensive or has a complex pricing structure. Or could have only the basic image-related features or not deliver excellent performance across the globe.

Enter ImageKit.io.

It is the only tool that we will need for image optimization and transformation with minimal effort and almost no changes to our existing infrastructure.

It is a complete image CDN with optimization and transformation capabilities for images on websites and apps. What does that mean?

Feed ImageKit.io an original, un-optimized image and fetch it using an ImageKit.io URL, and it shall deliver an optimized, rightly resized image to our user’s devices!

For example:

ImageKit.io resizes the image automatically by simply specifying the size in the image URL.

https://ik.imagekit.io/demo/img/tr:w-300,h-100/default-image.jpg

Here, the width and height of the final image are specified with “w” and “h” parameters in the URL. The output image has dimensions 300×100px, scaled down from an original size of 1000×1000px.

As we know, the right image formats can have a significant impact on our website’s bandwidth consumption.

For instance, the following PNG image,

https://ik.imagekit.io/demo/img/seo-img_E3VIYyKu6.jpg?tr=f-png

is almost 2.5x the size of its JPG variant.

ImageKit.io automatically uses the correct output image format based on image content, image quality, browser support, and user device capabilities. Also, the above image will be converted and delivered as a WebP for all browsers supporting the WebP image format.

Just turn it on, and we’re good to go!

And not just simple resizing and cropping, ImageKit.io allows for more advanced transformations like smart crop, image and text overlays, image trimming, blurring, contrast and sharpness correction, and many more. It also comes with advanced delivery features like Brotli compression for SVG images and image security. ImageKit.io is the solution to all our image optimization needs. And more.

It also comes bundled with a stellar infrastructure — AWS CloudFront CDN, multi-region core processing servers, and a media library with automatic global backups.

Integrations

It isn’t enough to find the most appropriate tool for our website. It should also provide an optimum experience fitting in just right with our existing setup.

With S3 bucket or other web servers

It is usually a tedious task to integrate any image optimization tool into our infrastructure. For example, for images, we would already have a CMS in place to upload the images. And a server or storage to store all of those images. We would not want to make any significant changes to the existing setup that could potentially disrupt all our team's processes.

But with ImageKit.io, the whole process from integration to image delivery takes just a few minutes. ImageKit.io allows us to plug our S3 bucket or webserver and start delivering optimized and transformed images instantly. No movement or re-upload of images is required. It takes just a few minutes to get the best optimization results.

Such simple integrations with AWS S3 or web servers are not available even with some leading players in the market.

Images fetched through ImageKit.io are automatically optimized and converted to the appropriate format. And we can resize and transform any image by just adding URL parameters.

For example:

Image with width 300px and height is adjusted automatically to preserve aspect ratio:

https://ik.imagekit.io/your_imagekit_id/rest-of-the-path.jpg?tr=w-300

or,

https://ik.imagekit.io/your_imagekit_id/tr:w-300/rest-of-the-path.jpg

We are using https://ik.imagekit.io/your_imagekit_id format for the URLs, but custom domain names are available with ImageKIt.io.

Media library

ImageKit.io also provides a media library, a feature missing in many prominent image optimization tools. Media library is a highly available file storage for all ImageKit.io users. It comes with a simple user interface to upload, search, and manage files, images, and folders.

With platforms like Magento and WordPress

Most SMBs use WordPress to build their websites. ImageKit.io proves handy and almost effortless to set up for these websites.

Installing a plugin on WordPress and making some minor changes in the settings from the WP plugin is all we need to do to integrate ImageKit.io with our WordPress website for all essential optimizations. Learn more about it here.

Similarly, we can integrate ImageKit.io with our Magento store. The essential format and quality optimizations do not require any code change and can be set up by making some changes in Settings in the Magento Admin Panel. Learn more about it here.

For advanced use cases like granular image quality control, smart cropping, watermarking, text overlays, and DPR support, ImageKit.io offers a much better solution, with more robust features, more control over the optimizations and more complex transformations, than the ones provided natively by WordPress or Magento. And we can implement them by making some changes in our website's template files.

With other CDNs

Most businesses use CDNs for their websites, usually under contracts, or running processes other than or in addition to image optimizations on these CDNs, or simply because a particular CDN performs better in a specific region.

Even then, it is possible to use ImageKit.io with our choice of CDN. They support integrations with:

• Akamai
• Azure
• Alibaba Cloud CDN
• CloudFlare (if one is on an Enterprise plan in CloudFlare)
• CloudFront
• Fastly
• Google CDN
• Zenedge

To ensure correct optimizations and caching on our CDN, their team works closely with their customer’s team to set up the configuration.

Custom domain names

As image optimization has become a norm, services like LetsEncrypt, which make obtaining and deploying an SSL certificate free, have also become standard practice. In such a scenario, enabling a custom domain name should not be charged heavily.

ImageKit.io helps us out here too.

It offers one custom domain name like images.example.com, SSL and HTTP2 enabled, free of charge, with each paid account. Additional domain names are available at a nominal one-time fee of $50. There are no hidden costs after that.

One ImageKit.io account, multiple websites

For image optimization needs for multiple websites or agencies handling hundreds of websites, ImageKit.io would prove to be an ideal solution. We’re free to attach as many “origins” (storages or servers) with ImageKit.io. What that means is each website has its storage or image server, which can be mapped to separate URLs within the same ImageKit.io account.

The added advantage of using ImageKit.io for multiple websites and apps is their pricing model. When one consolidates the usage across their many business accounts, and if it crosses the 1TB mark, they can reach out to ImageKit.io’s team for a special quote. Learn more about it here.

Multiple server regions

ImageKit.io is a global image CDN, It has a distributed infrastructure and processing regions around the world, in North Virginia (US East), North California (US West), Frankfurt (EU), Mumbai (India), Sydney (Australia) and Singapore, aiming to reduce latency between their servers and our image origins.

Additionally, ImageKit.io stores the images (transformed as well as original) in their cache after fetching them from our origins. This intermediate caching is done to avoid processing the images again. Doing so not only reduces the load on our origin servers and storage but also reduces data transfer costs from them.

Custom cache time

There are times when a shorter cache time is required. For cases where one or more images are set to change at intervals, while the others remain the same, ImageKit.io offers the option to set up custom cache times in place of the default 180 days preset in ImageKit.io, giving us more control over how our resources are cached.

This feature is usually not provided by third-party image CDNs or is available to enterprise customers only, but it is available with ImageKit.io on request.

Deliver non-image files through ImageKit.io CDN

ImageKit.io comes integrated with a CDN to store and serve resources. And while the primary use case is to deliver optimized images, it can do the same for the other static assets on our website, like JS, CSS as well as fonts.

There is no point dividing our static resources between two services when one, ImageKit.io, can do the whole job on its own.

It’s worth a mention here that though ImageKit.io provides delivery for non-image assets, it does not process or optimize them.

With ImageKit.io’s pricing model in mind, using their CDN may prove beneficial as it bills only based on one parameter — the total bandwidth consumed.

Cost efficiency

Most image optimization tools charge us for image storage or bill us based on requests or the number of master images or transformations.

ImageKit.io bills its customers on a single parameter, their output bandwidth. With ImageKit.io, we can optimize and transform to our heart’s content, without worrying about the costs they may incur. With our focus no longer on the billing costs, we can now focus on important tasks, like optimizing our images and website.

Usually, when an ImageKit.io account crosses 1TB total bandwidth consumption, that account becomes eligible for special pricing.

One can contact their team for a quote after crossing that threshold.

Final thoughts

Image optimization holds many benefits, but are we doing it right? And are we using the best service in the market for it?

ImageKit.io might prove to be the solution for all image optimization and management needs. But we don’t have to take their word for it.
