No. Banner rendering is a lookup in a font table built into the page, and image conversion samples the picture on a canvas in this tab. Neither sends anything anywhere.
Figlet-style fonts are separate data files. Bundling dozens would add a large download to every visit, and fetching them on demand would mean a network request — which this site does not do during a tool run. Four fonts ship inside the page instead.
Almost certainly because the destination is not using a monospaced font. ASCII art depends on every character having the same width; in a proportional font the columns drift and the picture falls apart.
A ramp ordered from dense to sparse. The default runs from @ through %#*+=-: to a space, so a dark pixel becomes a heavy character and a bright one becomes near-empty. A block-drawing ramp is also available for terminals that render it well.

How an image becomes characters
Converting a picture to ASCII is a resampling problem followed by a quantisation problem. First the image is reduced to a grid no wider than the requested column count, where each cell averages the pixels beneath it — that average is the cell's brightness. Then each brightness value is mapped onto a ramp of characters ordered by how much ink they put on the page, so a dark cell becomes @ or # and a bright one becomes a full stop or a space. One detail decides whether the result looks right: character cells are taller than they are wide, usually around twice as tall, so sampling on a square grid produces art that looks vertically stretched. Compensating for that aspect ratio when choosing the row count is the difference between a recognisable picture and a distorted one.
Where ASCII art still earns its place
Banner text survives because some places genuinely cannot render an image. A command-line tool printing its name at startup, a server login message, a README rendered in a plain-text context, the comment block at the top of a source file, a commit message — all of these are text-only channels where a logo has to be made of characters or not exist. That is also why monospacing matters so much: these are all contexts where a fixed-width font is guaranteed, which is exactly the assumption the art is built on. Paste the same output into an email client using a proportional font and it collapses, not because the art is wrong but because its one requirement was not met.
