Capacitor (Multi-) Photopicker Plugin

version npm issues license

The Photopicker API allows the user to select one or more photos from the system-wide media library.

The selected photos can be (down)scaled and compressed. The data is provided in the form of temporary files in the user's cache directory. The API provides the URIs of the processed photos.

In order to use the photos in a Capacitor application, they have to be moved from the cache directory to the final storage location.


npm install @enertrag/photopicker

(Of course, the usual Capacitor procedure npx cap sync must be executed afterwards.)

iOS Notes

Important: this plugin requires iOS 14 or later.

iOS requires the following usage description be added and filled out for your app in Info.plist:

  • NSPhotoLibraryUsageDescription (Privacy - Photo Library Usage Description)

Read about Configuring Info.plist in the iOS Guide for more information on setting iOS permissions in Xcode

Selected images are persisted in the users cache (temporary) folder. As mentioned you should move it to the final destination.

Android Notes

To use this plugin you have to register it in your MainActivity.

import ...
import com.enertrag.plugins.photopicker.Photopicker;

public class MainActivity extends BridgeActivity {

  public void onCreate(Bundle savedInstanceState) {

    // Initializes the Bridge
    this.init(savedInstanceState, new ArrayList<Class<? extends Plugin>>() {{
      // Additional plugins you've installed go here

On your MainActivity.java file add import com.enertrag.plugins.photopicker.Photopicker; and then inside the init callback add(Photopicker.class);

This API requires the following permissions be added to your AndroidManifest.xml:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

The storage permissions are for reading/saving photo files.

Read about Setting Permissions in the Android Guide for more information on setting Android permissions.


import { Plugins } from '@capacitor/core';
const { Photopicker } = Plugins;


async addPhotos() {

      const result = await Photopicker.getPhotos();
      if (result.selected) {

        for (const url of result.urls) {
            // ... do something with the url if it's not empty
            if(url) {
                // ...

Alternatively, if the code completion does not work, the import can be formulated as follows:

import { EAGPhotopicker } from 'enertrag-photopicker';
const Photopicker = new EAGPhotopicker();



getPhotos(options: PhotopickerOptions) => Promise<PhotopickerResponse>

Prompt the user to pick one or more photos from an album.

The method call may fail if the user denies the permission request.

Returns: Promise<PhotopickerResponse>
