  imports: [BrowserModule],
  providers: [NgxImageCompressService],
  bootstrap: [AppComponent]
})

import {Component} from '@angular/core';
import {NgxImageCompressService} from 'ngx-image-compress';
 
 
@Component({
  selector: 'app-root',
  template: `
    <<div *ngFor="let item of imgResultBeforeCompress;let i = index;">
  -----------------------------------------------------
  <span >
  <h1>before</h1>
  <img *ngIf="imgResultBeforeCompress[i]" class="responsive" [src]="imgResultBeforeCompress[i]" alt="">
  </span>
  <span  >
  <h1>After</h1>
  <img *ngIf="imgResultAfterCompress[i]" class="responsive" [src]="imgResultAfterCompress[i]" alt="">
  </span>
 
  <div style="float: unset;"></div>
  </div>
  `
})
export class AppComponent {
 
  constructor(private imageCompress: NgxImageCompressService) {}
  
  imgResultBeforeCompress = [];
  imgResultAfterCompress = [];
 
 compressFile() {
    this.imageCompress.uploadFile().then(({images, orientation}) => {
      this.imgResultBeforeCompress = images;
      for(let i = 0; i < images.length; i++){
      console.warn('Size in bytes was:', this.imageCompress.byteCount(images[i]));
      this.imageCompress.compressFile(images[i], orientation, 50, 50).then(
        result => {
          this.imgResultAfterCompress.push(result);
          console.warn('Size in bytes is now:', this.imageCompress.byteCount(result));
        }
      );
      }
    });
  }

How it's working underwood?

We will use Renderer2, and transform the image multiple time through HTML canvas encrustation. In fact you can use the static version into the library and import renderer by yourself.
