Compress images in React: React Image File Resize

Okay for this one I highly recommend, the speeds is just amazing. I loved it. I am gonna do a comparison real quick, between browser-image-compression and react-image-file-resizer.

`browser-image-compression`	`react-image-file-resizer`
Really fast	Compressed the same took a while
Quality option on the config	Only offers size limit
Return `base64` or `Blob`	Returns `Blob` only do the conversion yourself
No need to handle Promise	Must handle Promise
Specify compress format (png, webp, jpeg)	The compress format provided is the one returned

Below is an image I was able to compress with the following config



width -> 480px
height -> 480px
file format -> Set to JPEG
quality -> 50
rotation -> 0

Actual size: 1.6mb

Click on the link its a huge image and I just want the load time for this blog to be faster.

Compressed size: 16.3kb

Let's jump into how you can plug it into your React app

React Image File Resizer

Install the package



   yarn add react-image-file-resizer

Create your react component



   import React from "react";

   // ...

   class App extends React {
     // ...
     render() {
       return (
         <div className="App">
           // ...
           <h3>React Image File Resizer</h3>
           <br />
           <input
             type="file"
             id="file"
             accept="image/*"
             onChange={this.onFileResize}
           />
         </div>
       );
     }
   }

Start compressing



   ...
   import Compress from "react-image-file-resizer";

   ...
   onFileResize = e => {
       const file = e.target.files[0];

   Compress.imageFileResizer(
     file, // the file from input
     480, // width
     480, // height
     "JPEG", // compress format WEBP, JPEG, PNG
     70, // quality
     0, // rotation
     (uri) => {
       console.log(uri);
       // You upload logic goes here
     },
     "base64" // blob or base64 default base64
   );
   }

Again I highly recommend this library especially because it supports compressing to WEBP(files of this format are really fast).

Note: Set quality to 100 if you want to compress to PNG/WEBP(Lossless) else set the compress format to JPEG(Lossy)

We will cover understanding Lossy and Lossless compression.
