Answer 1

Base64 is a way to encode binary data as text (so it can be put anywhere you can put text, such as in an HTML attribute value).

The browser converts the Base64 data into whatever form it was in originally.

If that was a PNG it converts it back to a PNG. If it was a JPEG then a JPEG. And so on.

The browser doesn't convert the Base64 data directly to pixel values at all.
