Takes a Base64 string or a complete data URI and turns it back into a picture you can view and save.
It accepts either form: the full data URI beginning data:image/png;base64, or just the encoded part on its own. Line breaks and spaces are ignored, so a string copied out of a source file or a JSON response works as it is.
If the string is not valid Base64, or decodes to something that is not an image, you are told plainly rather than being handed a broken file.

Questions
It says my Base64 is not valid.
Usually the string was copied incompletely. Make sure you have the whole thing, from the first character to the last, with nothing cut off at either end.
What image format do I get back?
Whatever the data actually is. A data URI states its own type, and for a bare string the format is detected from the decoded content.
