File size reported from fs.stat does not match uploaded file size

let clip.uri = assets-library://asset/asset.JPG?id=9DC79222-EC93-45CA-9891-5D91AEDC5F7C&ext=JPG

let fd = new FormData()
let stats = await RNFetchBlob.fs.stat(clip.uri)
fileSize = stats.size
fileObj = {

try {
	return fetch(url, localOptions, callback)
} catch (e) {}

}

reported file size from fs.stat === 178,849 bytes
actual uploaded file size === 395,394 bytes

It seems that RNFetchBlob is uploading an uncompressed version of the file. Is there a way to make RNFetchBlob either report the uncompressed size or better yet, upload the file that was stat'ed?
