Introduction
 0:00 |
You can display Cloudinary-hosted images on your website using HTML, or you can use the CldImage component from the Svelte community-developed library for simplified access to Cloudinary's transformation and optimization features. |
Deliver an image using an the Cloudinary CldImage component
| 0:31 |
Once Svelte Cloudinary is installed, import the CldImage component into your project and replace your existing image tag with CldImage. In addition, instead of referencing the entire delivery URL, just specify the public ID. |
Automatically optimize your images
| 0:59 |
When using the CldImage component, your images are delivered with f_auto and q_auto by default. This means they're automatically delivered in the best format for the requesting browser and compressed for optimal performance while maintaining visual quality. |
Format your image as a square
| 1:17 |
You can crop an image to a height and width of 600 pixels with the fill crop mode, to format your image as a square. |
Automatically focus on the most important part of the image
| 1:34 |
Use the AI-based gravity="auto" property to ensure that all cropped images center on the essential area, avoiding any unwanted cuts. |
Apply any transformation using the CldImage component
| 1:41 |
The CldImage component provides access to all Cloudinary transformations, such as special effects, text and image overlays, and more. |
