Ngx Photo Editor for Angular

NPM version The MIT License The MIT License



Getting started

Step 1: Install ng-bootstrap

   ng add @ng-bootstrap/ng-bootstrap

Step 2: Install ngx-photo-editor

    npm install ngx-photo-editor --save

Example usage:

Add the NgxPhotoEditorModule to the imports of the module.

      import {NgxPhotoEditorModule} from "ngx-photo-editor";

  imports: [

Add the element to your HTML:

<div><input type="file" (change)="fileChangeEvent($event)"/></div>


<img [src]="base64" alt="">

And add this to your ts file:

import {CroppedEvent} from 'ngx-photo-editor';

export class AppComponent {
  imageChangedEvent: any;
  base64: any;

  fileChangeEvent(event: any) {
    this.imageChangedEvent = event;

  imageCropped(event: CroppedEvent) {
    this.base64 = event.base64;

When you choose a file from the file input, it will trigger fileChangeEvent. That event is then passed to the ngxPhotoEditor through imageChangedEvent which will load the image into the cropper. Everytime you release the mouse, the imageCropped event will be triggerd with the cropped image as a Base64, Blob in its payload.


All inputs are optional. Either the imageChangedEvent, imageBase64 or imageFile or imageUrl should be set to load an image into the cropper.

imageChangedEvent FileEvent The change event from your file input
imageFile Blob(File) The file you want to change
imageBase64 string If you don't want to use a file input, you can set a base64 image directly and it will be loaded into the cropper
imageURL string If you don't want to use a file input or a base64 you can set an URL to get the image from. If requesting an image from a different domain make sure Cross-Origin Resource Sharing (CORS) is allowed or the image will fail to load.

  • Type: Number
  • Default: 0
  • Options:
    • 0: no restrictions
    • 1: restrict the crop box to not exceed the size of the canvas.
    • 2: restrict the minimum canvas size to fit within the container. If the proportions of the canvas and the container differ, the minimum canvas will be surrounded by extra space in one of the dimensions.
    • 3: restrict the minimum canvas size to fill fit the container. If the proportions of the canvas and the container are different, the container will not be able to fit the whole canvas in one of the dimensions.

Define the view mode of the cropper. If you set viewMode to 0, the crop box can extend outside the canvas, while a value of 1, 2 or 3 will restrict the crop box to the size of the canvas. A viewMode of 2 or 3 will additionally restrict the canvas to the container. Note that if the proportions of the canvas and the container are the same, there is no difference between 2 and 3.
