If you require to utilize image upload with a crop then you can facilely use the ngx-image-cropper npm package. it will provide you Cropping, Zooming, Scaling, and Preview functionality while uploading time. it's very facilely used with your angular 10 application.

Step - 1: Create New App

You can easily create your angular app using bellow command:

ng new ngImageCrop

In this step, we will install the ngx-image-cropper npm package for uploading the image crop function in angular. so let's run both commands:

npm install ngx-image-cropper --save

Step - 3: Import ImageCropperModule

Now, here we will import ImageCropperModule from ngx-image-cropper and then we add on declarations part. so let's update the app.module.ts file as like bellow:


import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { ImageCropperModule } from 'ngx-image-cropper';
  declarations: [
  imports: [
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }

Step - 4: Update Component ts File

Here, we will update app.component.ts file here, in this file we will write fileChangeEvent(), imageCropped(), imageLoaded(), cropperReady() and loadImageFailed() that provided by ngx-image-cropper.

You can update as bellow app.component.ts file.


import { Component } from '@angular/core';
import { ImageCroppedEvent } from 'ngx-image-cropper';
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
  title = 'ngImageCrop';
  imageChangedEvent: any = '';
    croppedImage: any = '';
    fileChangeEvent(event: any): void {
        this.imageChangedEvent = event;
    imageCropped(event: ImageCroppedEvent) {
        this.croppedImage = event.base64;
    imageLoaded() {
        /* show cropper */
    cropperReady() {
        /* cropper ready */
    loadImageFailed() {
        /* show message */

Step - 5: Update HTML File

I used bootstrap class on this form.

Here, we will update the HTML file as like below, so update it as like bellow:


<div class="container">
    <div class="card">
      <div class="card-header">

      <div class="card-body">
        <input type="file" (change)="fileChangeEvent($event)" />
        <div class="row" style="margin-top: 15px;">
            <div class="text-center col-md-8">
                <h5>Crop Image</h5>
                [aspectRatio]="4 / 4"
            <div class="text-center col-md-4">
                <img [src]="croppedImage" />
