    React Native Image Resizer

    A React Native module that can create scaled versions of local images (also supports the assets library on iOS).


    Install the package:

    • React Native >= 0.60
    yarn add react-native-image-resizer
    cd ios && pod install
    • React Native <= 0.59
    yarn add react-native-image-resizer
    react-native link react-native-image-resizer


    Note: on latest versions of React Native, you may have an error during the Gradle build on Android (com.android.dex.DexException: Multiple dex files define Landroid/support/v7/appcompat/R$anim). Run cd android && ./gradlew clean to fix this.

    Usage example

    import ImageResizer from 'react-native-image-resizer';
    ImageResizer.createResizedImage(imageUri, newWidth, newHeight, compressFormat, quality, rotation, outputPath, imageName).then((response) => {
      // response.uri is the URI of the new image that can now be displayed, uploaded...
      // response.path is the path of the new image
      // response.name is the name of the new image with the extension
      // response.size is the size of the new image
    }).catch((err) => {
      // Oops, something went wrong. Check that the filename is correct and
      // inspect err to get more details.

    Sample app

    A basic, sample app is available in the example folder. It uses the module to resize a photo from the Camera Roll.


    promise createResizedImage(path, maxWidth, maxHeight, compressFormat, quality, rotation = 0, outputPath, imageName)

    The promise resolves with an object containing: path, uri, name, size (bytes), width (pixels), and height of the new file. The URI can be used directly as the source of an <Image> component.

    Option Description
    path Path of image file, or a base64 encoded image string prefixed with 'data:image/imagetype' where imagetype is jpeg or png.
    maxWidth Image max width (ratio is preserved)
    maxHeight Image max height (ratio is preserved)
    compressFormat Can be either JPEG, PNG or WEBP (android only).
    quality A number between 0 and 100. Used for the JPEG compression.
    rotation Rotation to apply to the image, in degrees, for android. On iOS, rotation is limited (and rounded) to multiples of 90 degrees.
    outputPath The resized image path. If null, resized image will be stored in cache folder. To set outputPath make sure to add option for rotation too (if no rotation is needed, just set it to 0).
    imageName Name of image.
