Drag and drop is a common interaction method, It is primaryly used to amplify the user experience when it comes to move objects or data from one location to another by clicking, holding, dragging.

We will use drag and drop feature to build image upload in React and also show image preview using the functional component.

How to Upload Image Files, Show Image Preview with Progress Percentage Bar in React

  • Step 1: Install New React Project
  • Step 2: Install Bootstrap Package
  • Step 3: Add React Dropzone Package
  • Step 4: Install HTML File Selector Package
  • Step 5: Create and Register File Upload Component
  • Step 6: Implement React Dropzone in React Component
  • Step 7: Start React Application

Install New React Project

Invoke the first step by creating a brand new React app; if you already know this process, then you are good to go to the subsequent step.

npx create-react-app react-social

Get into the project root.

cd react-social

Install Bootstrap Package

This step is optional; we are using the Bootstrap CSS framework to ramp up the UI of the image upload module; you can ignore this plugin if you want.

npm i bootstrap --legacy-peer-deps

Add React Dropzone Package

In this section, you will likely install the react-dropzone-uploader package in React application; make sure to add the required packages’ in the file upload component file.

npm i react-dropzone-uploader --legacy-peer-deps

Install HTML File Selector Package

Next, install the html5 file selector package; it eloquently deals with custom input control that handles the files array chosen by file input control.

npm i html5-file-selector

Create and Register File Upload Component

Ideally, components are independent and reusable pieces of code that are used to manage code eloquently.

They are very much identical to programming functions; however, they work independently and return HTML through a render() function.

Next, create src/components folder, then fileUpload.component.js file within.

Once the new component is created, then place the following code in the src/components/fileUpload.component.js file.

import React from 'react';
import 'react-dropzone-uploader/dist/styles.css'
import Dropzone from 'react-dropzone-uploader'
import { getDroppedOrSelectedFiles } from 'html5-file-selector';

const FileUploadComponent = () => {
export default FileUploadComponent;

There after, move to the src/App.js file and update the given code within the file.

import React from 'react';
import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
import './App.css';
import FileUploadComponent from './components/fileUpload.component';
function App() {
  return (
    <div className="App container mt-5">
      <FileUploadComponent />
export default App;

Implement React Dropzone in React Component

Next, we are going to integrate the drag and drop image files upload with the image preview feature, not just that.

We will also show you how to create a percentage progress bar and how to blitzkrieg several other functionalities that are essential and build using dropzone’s methods and event handlers.

Add code in src/components/fileUpload.component.js file.

import React from 'react';
import 'react-dropzone-uploader/dist/styles.css'
import Dropzone from 'react-dropzone-uploader'
import { getDroppedOrSelectedFiles } from 'html5-file-selector'

const FileUploadComponent = () => {
    const fileParams = ({ meta }) => {
        return { url: '' }
    const onFileChange = ({ meta, file }, status) => { 
        console.log(status, meta, file) 
    const onSubmit = (files, allFiles) => {
        allFiles.forEach(f => f.remove())
    const getFilesFromEvent = e => {
        return new Promise(resolve => {
            getDroppedOrSelectedFiles(e).then(chosenFiles => {
                resolve( => f.fileObject))
    const selectFileInput = ({ accept, onFiles, files, getFilesFromEvent }) => {
        const textMsg = files.length > 0 ? 'Upload Again' : 'Select Files'
        return (
            <label className="btn btn-danger mt-4">
                    style={{ display: 'none' }}
                    onChange={e => {
                        getFilesFromEvent(e).then(chosenFiles => {
    return (
            inputContent="Drop A File"
                dropzone: { width: 600, height: 400 },
                dropzoneActive: { borderColor: 'green' },
export default FileUploadComponent;

Start React Application

In the eventual step, you have to start the react app; this helps to check the subtle nuances in the file upload functionality we have just added in react.

npm start
