The classic meme typeface is used, with a fallback to a heavy sans-serif if the browser does not have it. Because the font may not be installed on every device, the rendered result can look slightly different from another machine that shares the same meme.

Why does my caption look too big or too small?

The font size you choose is scaled to the height of the picture and then reduced further if the line is too wide to fit the frame, so long lines wrap into several rows instead of running off the edge. Raise the size for a punchier look and lower it for a subtler one.

Does the outline really help?

Yes. A dark outline around light text, or a light outline around dark text, keeps the words readable when the photo behind them is busy. Set the outline thickness to zero for a clean flat look, or raise it when the background is busy.

Is my image uploaded?

No. The picture is drawn on a canvas inside the page, and the finished meme is generated from that canvas and downloaded directly. Nothing is sent to a server.
