Top reasons to choose ImageKit

1. Secure native integration with all leading object storage providers

You can complete the integration within 10 minutes by plugging ImageKit with existing storage instead of moving images to our storage. ImageKit offers secure native integration with Amazon S3, Firebase, Azure, Wasabi, Google Cloud, WordPress, or Magento to instantly get all real-time resizing and automatic optimization.

2. Easy to use media library

ImageKit provides a simple interface to upload, manage, search, and tag resources for efficient digital asset management in the cloud. Your marketing team will love it.

3. A vast array of image transformations

ImageKit offers 40+ image transformations so that you can adapt the image based on your layout. Smart crop and face crop features allow you to create perfect thumbnails.

5. Superior technical support

Most of the time, you won't have to speak with us, but you will be impressed when you do.

6. Faster processing timings

ImageKit has a multi-region image processing network that comes with every plan. It means, no matter where your original images are stored, first fetch timings will be minimal.

7 Performance monitoring

ImageKit has in-built automatic performance monitoring and alerting for key business pages.

8. Single account for multiple websites

You can use a single account for many websites and leverage volume discounts—no fuss about where and how you use it.

Top reasons to choose ImageEngine

The truly unique feature of ImageEngine is how device detection is built in as a core feature. The leading device detection library WURFL is built into ImageEngine. It detects the device based on the User-Agent value and automatically resizes and converts format. However, there are two downsides to this approach:

  • A low cache hit ratio - There is so much variety in the User-Agent header that many will only be seen once. The website UserAgentString identifies over 11,000 unique user agent strings.
  • Detecting device attributes, i.e., viewport size, display DPR, etc., from User-Agent, has known to be error-prone. It might result in undesired outcomes for a few users.

Feature comparison

Both products have been around for a long time and have all the features you need to store, resize, and deliver optimized images within milliseconds. However, each has certain unique advantages that could make your life easy, depending upon your use-cases.

ImageKit Features

Here is the list of features that are unique to ImageKit:

  • Media Library
  • Performance Center
  • SEO based Image URL generation
  • AI-based smart crop and face crop
  • Advance Image manipulations & transformations such as : Chained transformation & Named transformation

Media library

ImageKit has a simple interface to upload, manage, search, and tag resources for efficient digital asset management in the cloud. Your marketing team will love it. ImageEngine's doesn't have a media library.

ImageKit media library has co-located storage in all 6 geographic regions. It has two benefits:

  • It will improve your first fetch timings. The processing server is in the same AWS region where the image is stored. The download timings are minimal, and your data doesn't even leave the AWS datacenter.
  • It will help you with GDPR compliance. For example, if you choose the Frankfurt region, your assets will be stored in only the Frankfort region.

Here is how the media library works in ImageKit:

Digital asset management

Upload, organize and distribute assetsCreate, copy, move and delete multiple files and folders using an intuitive interface.
Copy ready-to-use URLsGet optimized image URLs and embed them in a blog post, landing page or email.
Quickly find the right assetSearch the assets for your campaigns and landing pages using tags and advanced search filters.

Performance monitoring & alerting

This feature is unique to ImageKit. You will get an in-depth image optimization report for key business pages delivered to your inbox. This allows your team to proactively fix issues without having to check generic web-performance reports in third party tools manually.

  • Get actionable advice that will fix performance issues immediately.
  • Automatic daily analysis on desktop and mobile devices.
  • Performance insights delivered to your inbox.

Here is how a typical alert email looks like:

Advanced image transformation & manipulations

ImageKit has more than 40 URL parameters for image manipulation. You can dynamically adapt images as you want to fit the layout. Here are some URL based transformations that you can do with ImageKit:

  • Resize
  • Crop image
  • Quality
  • Focus
  • Format
  • Blur
  • Image enhancement and color manipulations
  • Overlay images

You can read about the complete list of transformations in our docs.

Apart from a vast array of image transformations options, ImageKit offers named transformation and signed URL.

Let's see how image manipulation works in ImageKit:

Deliver responsive imagesAdapt images using height, width, crop, aspect ratio, and DPR transformations.
Add watermark and text overlaysLeverage more than 40 URL-based transformations to modify the image exactly as you like.
Show perfect thumbnailsGenerate attention-grabbing thumbnails using content-aware smart cropping and face detection.

Show perfect thumbnail example
https://ik.imgkit.net/ikmedia/bucket.png?tr=w-400,h-333,dpr-2,fo-auto:r-max

SEO-friendly image URLs

In ImageKit.io, you can give your images an SEO-friendly name without modifying the actual file name in the storage.

For example, the following image:

https://ik.imgkit.net/demo/DSC1234.jpg

can be accessed over an SEO-friendly URL as follows:

https://ik.imgkit.net/demo/ik-seo/DSC1234/eiffel-tower.jpg

Learn more from the docs.

AI-Based Smart crop & Face crop

Commonly, center cropping is the go-to cropping strategy for generating thumbnails, i.e., preserving the center of the image and crop out the edges. While this sounds fine, it fails when the subject of the image is not centered!

Take a look at the following cases where center cropping results in a poor thumbnail:

Original images (scaled down)Image thumbnails 150×200px

ImageKit's smart crop is a content-aware cropping method that analyses the image and ensures that its most critical part is preserved while generating the thumbnail.

Let's compare the results with smart cropping:

ImageEngine Features

ImageEngine offers a basic set of essential operations for an image CDN; however, it provides fewer image transformations & manipulations than ImageKit.

Integration comparison

ImageKit is built to integrate with your existing setup in minutes.

No need to move imagesUse with AWS S3, DigitalOcean, Firebase, any web server, ELB, WordPress, Magento or Web Proxy.
Use your domain nameFor example, use https://img.example.com for better SEO and control.
Use in-built AWS CloudFront or your CDNIntegrate with Akamai, CloudFlare, Fastly, Azure, Google CDN, Alibaba Cloud CDN or Limelight.

A few highlights of ImageKit are:

  • No URL change required - setup the same custom domain and start delivering optimized images. It comes with a paid plan, which is $49 per month.
  • Secure integration with all leading object storage - Native integration with Amazon S3, DigitalOcean Spaces, Google Cloud Storage, Firebase, Ali storage, Wasabi, and other S3-compatible storages. Available on all plans.
  • Integrate with any web server - Attach any public server or load balancer, e.g., Magento, WordPress, Shopify, AWS EC2, or ELBs. Available on all plans.
  • Fetch any remote URL - Optimize & transform any public image through ImageKit using Web Proxy origin. Available on all plans.
  • Manage multiple websites in the same account - Add multiple external storages and access them on unique URL endpoints. Available on all plans.
  • Use in-built AWS CloudFront or your CDN - Integrate with Akamai, CloudFlare, Fastly, Azure, Google CDN, Alibaba Cloud CDN, or Limelight. It comes with a minimum monthly billing of $300.

ImageEngine can only integrate with Amazon S3, google cloud, and the webserver.

Infrastructure comparison

ImageKit.io uses an established Global CDN with 200 plus caching nodes and can serve cached images in sub-milliseconds. ImageEngine has a self-managed network of 18 caching servers, which might not give all users optimal performance.

Apart from a well known global CDN, ImageKit has the advantage of a multi-region core processing network, which decreases the response time for new transformations and increases overall uptime.

ImageKit was the first one to offer multi-region co-located storage.

CDNAmazon CloudFrontSelf-managed
Core processing locations6 regions available on all plans (North California, North Virginia, Singapore, Frankfurt, Sydney, Mumbai)Unknown

Pricing comparison

ImageKit has a predictable and simple to understand pricing model. In most cases, your monthly cost depends on viewing bandwidth. If you use advanced features such as video manipulation or extensions, you pay as per actual usage.

Few good points about ImageKit pricing:

  • Free plan option.
  • Small overage unit. It means your cost increases proportionally to your site traffic.
  • Unlimited master images.
  • Unlimited image transformations.
  • Unlimited thumbnail storage.

Apart from bandwidth inclusions, the difference between free and paid plan is:

  • One custom domain name, e.g., images.example.com.
  • One time 30 min consultation call will cover how you can improve website performance and user experience.
  • Automated performance monitoring and alerting.
  • Live chat support.
  • User management.

ImageEngine does not have a free plan; however, they do have a 60-day trial that you can use to experience the product. ImageEngine also charges based on optimized bandwidth usage similar to ImageKit.

Uptime comparison

In ImageKit, six image processing regions act as a failover for each other if one region goes down. This type of distributed architecture not only improves the TTFB for the first image fetch but also make ImageKit more available. ImageKit is committed to expanding its infrastructure in other regions in the future.

Based on the status pages, ImageKit seems to be more transparent about past incidents. You will see recent uptime reports for different regions from a single view without further digging.

ImageEngine doesn't have a public status page as of 11 Nov 2020.

Support comparison

ImageKit offers live chat support. You can initiate a conversation with us from the dashboard, docs, or any page on the website. You will get expert advice from actual engineers.

Here is a screenshot of our Intercom's conversation ratings.
