WEBP format doesn't work on iOS?

[Reagankm]

I'm using "@bam.tech/react-native-image-resizer": "^3.0.4", and I call the resizer like this:

export const resizeImageToMax = (uri: string): Promise<ResizerResponse> => {
    return ImageResizer.createResizedImage(
        uri,
        photoUploadMaxWidth,
        photoUploadMaxWidth,
        'WEBP',
        100,
        0,
        undefined,
        false,
        { onlyScaleDown: true }
    );
}

On Android it works fine. On my iOS emulator I get this error:

If I change the format to 'JPEG' then it works on iOS, but I really want to use WEBP, especially since it is supported natively as of iOS 14.

@Reagankm

As specified in the README, WEBP format is at the moment only supported on Android:

react-native-image-resizer/README.md

Line 86 in 254e4df

| compressFormat | Can be either JPEG, PNG or WEBP (android only). |

Any contribution is welcome 🙂

Ah. Sorry, I missed that. I went a different way for my resizer library, but I appreciate the work you've put into this. It seems like a great utility
