Is my encoding of bitmap usable for other platforms?

Multi tool use
My question is is an encoded string generated with the code below usable on another platforms and if not - how do I make it? The code is working good on android, but I am not sure what will happen if I try to expand the project.
This is the code for generating the string:
private String BitMapToString(Bitmap bitmap){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 50, baos);
byte b = baos.toByteArray();
String imageEncoded = Base64.encodeToString(b, Base64.NO_WRAP);
return imageEncoded;
}
And this is the code for decoding it:
private Bitmap StringToBitMap(String encodedString){
byte decodedByte;
try {
decodedByte = Base64.decode(encodedString, 0);
} catch(Exception e) {
return null;
}
return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length);
}
I'm sending the string to the database and retrieving it and everything works just fine hence I can display the image. But is it usable elsewhere? And if not - how do I make it?
java

Define "elsewhere". Sure, if you implemented equivalent transforms in another app ... or another programming language ... it should work. Provided that you implement them correctly.

Lets say I get that string and try to decode it on JS or swift. Will it be okay or I have to use for example UTF-8 encoding somehow in my code?

You don't need to use UTF-8 with Base64. Any encoding that will support a subset of the ASCII / LATIN 1 charset will do. Digits, lowercase and uppercase letters,+
and/
are all that are required. Read up on the spec for base64 encoding. (Google it)
