#17 Fix picture format

Sharing a JPG to this app saves a PNG file on storage, making the final file much larger

Can you fix it? or does a quality loss occur?

App has not ability to change the file format. It takes file extension from mime type but mime type is sets by Sender. Mime type can be differ from file ext.

Can you save an example as file and attach it to the issue?

Can't reproduce with another app, your app is not to blame
