React Native Image Picker
A React Native module that allows you to select a photo/video from the device library or camera.
Make sure you're reading the doc applicable to your version, for example if you're using version 3.8.0 go to tag 3.8.0 and read those docs. This doc is always that of main branch.
Also read version release notes for any breaking changes especially if you're updating the major version.

yarn add react-native-image-picker
# RN >= 0.60
cd ios && pod install
# RN < 0.60
react-native link react-native-image-pickerPost-install Steps
iOS
Add the appropriate keys to your Info.plist,
If you are allowing user to select image/video from photos, add NSPhotoLibraryUsageDescription.
If you are allowing user to capture image add NSCameraUsageDescription key also.
If you are allowing user to capture video add NSCameraUsageDescription add NSMicrophoneUsageDescription key also.
Android
No permissions required (saveToPhotos requires permission check).
Note: This library does not require Manifest.permission.CAMERA, if your app declares as using this permission in manifest then you have to obtain the permission before using launchCamera.

| includeBase64 | OK | OK | OK | If true, creates base64 string of the image (Avoid using on large image files due to performance) | |
| includeExtra | OK | OK | NO | If true, will include extra data which requires library permissions to be requested (i.e. exif data) | |
| saveToPhotos | OK | OK | NO | (Boolean) Only for launchCamera, saves the image/video file captured to public photo | |
| selectionLimit | OK | OK | OK | Default is 1, use 0 to allow any number of files. Only iOS version >= 14 & Android version >= 13 support 0 and also it supports providing any integer value | |

The Response Object
| key | iOS | Android | Web | Description |
|---|---|---|---|---|
| didCancel | OK | OK | OK | true if the user cancelled the process |
| errorCode | OK | OK | OK | Check ErrorCode for all error codes |
| errorMessage | OK | OK | OK | Description of the error, use it for debug purpose only |
| assets | OK | OK | OK | Array of the selected media, refer to Asset Object |
Asset Object
| key | iOS | Android | Web | Photo/Video | Requires Permissions | Description |
|---|---|---|---|---|---|---|
| base64 | OK | OK | OK | PHOTO ONLY | NO | The base64 string of the image (photos only) |
| uri | OK | OK | OK | BOTH | NO | The file uri in app specific cache storage. Except when picking video from Android gallery where you will get read only content uri, to get file uri in this case copy the file to app specific storage using any react-native library. For web it uses the base64 as uri. |
| width | OK | OK | OK | BOTH | NO | Asset dimensions |
| height | OK | OK | OK | BOTH | NO | Asset dimensions |
| fileSize | OK | OK | NO | BOTH | NO | The file size |
| type | OK | OK | NO | BOTH | NO | The file type |
| fileName | OK | OK | NO | BOTH | NO | The file name |
| duration | OK | OK | NO | VIDEO ONLY | NO | The selected video duration in seconds |
| bitrate | --- | OK | NO | VIDEO ONLY | NO | The average bitrate (in bits/sec) of the selected video, if available. (Android only) |
| timestamp | OK | OK | NO | BOTH | YES | Timestamp of the asset. Only included if 'includeExtra' is true |
| id | OK | OK | NO | BOTH | YES | local identifier of the photo or video. On Android, this is the same as fileName |
| originFilepath | NO | OK | NO | PHOTO ONLY | YES | thr origin file path when select image |
waring: the uri is point at a temporary file! When you pick a same image twice, it will be two different uri,
the fileName also to be the temporary file's name.
Note on file storage
Image/video captured via camera will be stored in temporary folder so will be deleted any time, so don't expect it to persist. Use saveToPhotos: true (default is false) to save the file in the public photos. saveToPhotos requires WRITE_EXTERNAL_STORAGE permission on Android 28 and below (You have to obtain the permission, the library does not).
For web this doesn't work.
ErrorCode
| Code | Description |
|---|---|
| camera_unavailable | camera not available on device |
| permission | Permission not satisfied |
| others | other errors (check errorMessage for description) |
