No. A plain Base64 string works too, and the tool detects the image type from the first bytes of the file.

The usual causes are missing padding, line breaks inside the string, or characters that were copied incorrectly.
Strings of a few megabytes work, but very large ones can make the browser slow, so keep the image reasonably small.
Yes. Pick PNG, JPEG or WebP in the output selector and the image is redrawn on a canvas before the download starts.
