How to Use Imagekit

Get started in a few simple steps

1

Connect Your Storage

Sign up at imagekit.io and connect your existing media storage - S3, Google Cloud Storage, Azure, or other sources. ImageKit sits in front of your storage and transforms media on delivery.

2

Update Your Image URLs

Replace your direct storage URLs with ImageKit URLs. Add transformation parameters to the URL to resize, crop, or optimize - no manual image processing required.

Monitor Performance

Use the ImageKit dashboard to track delivery performance, see how much bandwidth optimization is saving, and identify opportunities to improve media loading times further.


ImageKit.io's Core Features in Detail

Powerful features from ImageKit.io

Zero Manual Processing

Creating multiple image variants for different screen sizes and formats manually is tedious and error-prone. ImageKit does this automatically through URL parameters eliminating the image processing pipeline

Real-Time Adaptability

URL-based transformations mean you can change how an image is delivered without re-processing and re-uploading - just change the URL parameters and the transformation changes immediately

Modern Format Adoption

WebP and AVIF can reduce image file sizes by 30-50 percent versus JPEG. ImageKit automatically serves these formats to browsers that support them without any code changes

CDN Performance

Delivering optimized images through a global CDN means users get fast media regardless of their geographic location relative to your origin storage
