Frequently Asked Questions
Does it matter if my text has a data: prefix or is broken over several lines?
No. The prefix is detected and removed, line breaks, spaces and surrounding quotes are ignored, percent-escapes copied out of a URL are turned back, and the URL-safe - and _ characters are read as + and /. The page then lists exactly what it took out of the paste, so nothing is changed silently.
What decides the name and extension of the downloaded file?
The decoded bytes, not the prefix. Their header is read to work out whether this really is a PNG, JPEG, GIF, WebP or SVG, and the file is named from that. If the prefix claims a type the bytes disagree with, the page says so and follows the bytes. Text that decodes but is not a recognisable picture is still handed back as those exact bytes.
