Setting Up Your Cloudinary Account

1. Go to the Cloudinary website and sign up for a free account. You can log in if you have an account already.

2. Once you’ve signed up, log in to your account and navigate to the Dashboard. In the Dashboard, you’ll see your Cloudinary Cloud Name, API Key, and API Secret. You’ll need these credentials to integrate Cloudinary with your React JS app. So copy these and save them somewhere else.

Installing and Setting Up Cloudinary React SDK

1. Now that you have your Cloudinary account set up, it’s time to install and set up the Cloudinary React SDK. It’s the official SDK from Cloudinary. Install the Cloudinary React SDK using npm or yarn

npm install cloudinary-react
#or
yarn add cloudinary-react

2. The Cloudinary API key includes a cloud name, API key, and API secret which we have got after signing up in Cloudinary. We need to add these credentials to our React JS application. We can do this by creating a .env file in the root of our project and adding the following lines.

// .env
REACT_APP_CLOUDINARY_CLOUD_NAME=your_cloud_name
REACT_APP_CLOUDINARY_API_KEY=your_api_key
REACT_APP_CLOUDINARY_API_SECRET=your_api_secret
REACT_APP_CLOUDINARY_UPLOAD_PRESET=your_preset_name

Advanced Image Features of Cloudinary

We have a Cloudinary account and we have installed the Cloudinary React SDK. Now we can dive into the Advanced Image Features of Cloudinary. This advanced feature includes image cropping, face detection, image filter and many more.

If you want the detailed code for these features you can find it on GitHub.

You can also check all the examples of features in the demo

In the code examples, you’ll find CLOUD_NAME which is basically the cloud name which is saved in .env file.

const CLOUD_NAME = process.env.REACT_APP_CLOUDINARY_CLOUD_NAME;

The url is the image public_id for the image which can get in the Cloudinary. You can also get a public_id in response after uploading the image to CLoudinary.

1. Resizing and Cropping Images in Cloudinary

You can easily resize and crop images using Cloudinary’s image manipulation features. You can specify the width, height, and crop mode to achieve the desired result. For example, if you want to resize an image to a width of 500 pixels and crop it to fit, you can use the following code:

<Image 
  cloudName={CLOUD_NAME}
  publicId={url} 
  width="500" 
  crop="scale" 
/>

2. Applying Filters and Effects with Cloudinary

Cloudinary provides a wide range of filters and effects that you can apply to your images. For example, you can apply a grayscale filter to an image by adding the “effect” attribute to the Image component:

<Image 
  cloudName={CLOUD_NAME} 
  publicId={url} 
  effect="grayscale" 
/>

3. Adjusting Image Quality with Cloudinary

You can optimize your images for the web by adjusting the image quality. Cloudinary automatically compresses images to reduce file size without sacrificing quality. You can use the “quality” attribute to specify the desired level of compression. For example, to automatically optimize the image for the web, you can use the following code:

<Image 
  cloudName={CLOUD_NAME} 
  publicId={url} 
  quality="auto" 
/>

4. Converting image formats with Cloudinary

You can convert images to different formats using Cloudinary’s format conversion features. For example, you can convert a JPEG image to a PNG image by adding the “format” attribute to the Image component:

<Image 
  cloudName={CLOUD_NAME} 
  publicId={url} 
  format="png" 
/>

5. Adding Watermarks with Cloudinary

Cloudinary-React also supports adding watermarks to your images to protect them from unauthorized use or to promote your brand. The overlay transformation option allows you to add an image or text as a watermark on top of your original image. Here’s an example

<Image
  cloudName={CLOUD_NAME}
  publicId={url}
  transformation={{
    width: 400,
    height: 400,
    crop: 'thumb',
    overlay: {
      font_family: 'Arial',
      font_size: 40,
      text: 'My Watermark',
    },
  }}
/>

6. Face detection and recognition with Cloudinary

Cloudinary provides built-in support for face detection and recognition. You can use the “gravity” attribute to automatically crop an image to focus on faces. You can also use the “faces” attribute to retrieve information about faces detected in an image. For example, you can use the following code to crop an image to focus on faces:

<Image
  cloudName={CLOUD_NAME}
  publicId={url}
  transformation={{
    width: 400,
    height: 400,
    crop: "thumb",
    face: "auto",
  }}
/>

7. Text and image overlays with Cloudinary

You can add text and image overlays to your images using Cloudinary’s overlay features. You can specify the position, size, and opacity of the overlay. For example, to add a text overlay to the top-left corner of an image, you can use the following code:

<Image
  cloudName={CLOUD_NAME}
  publicId={PUBLIC_ID}
  overlay="text:arial_30_bold:Hello World!"
  gravity="north_west"
/>

8. Blur Faces with Cloudinary

Another useful feature of Cloudinary-React is the ability to blur faces in an image. This can be useful for protecting the privacy of individuals in images, especially in cases where the images are used for public display or sharing. Here’s an example:

<Image
  cloudName={CLOUD_NAME}
  publicId={url}
  transformation={{
    width: 400,
    height: 400,
    crop: 'thumb',
    effect: 'pixelate_faces',
    gravity: 'auto',
  }}
/>

9. Image Placeholder with Cloudinary

Cloudinary-React supports image placeholders, which can help to improve the perceived performance of your application by displaying a low-resolution version of the image while the full-sized version is loading. Here’s an example:

<Image 
   cloudName="demo" 
   publicId="sample"
   placeholder="blur" 
/>

10. Multiple Transformation with Cloudinary

With Cloudinary-React, you can chain multiple transformations together to create complex image transformations. Here’s an example:

<Image
  cloudName={CLOUD_NAME}
  publicId={url}
  transformation={{
    width: 400,
    height: 400,
    crop: "fill",
    effect: "brightness:20",
    angle: 45,
    border: "2px_solid_black",
  }}
/>
