Personally I like this.

convert -density 300 -trim test.pdf -quality 100 test.jpg

It's a little over twice the file size, but it looks better to me.

-density 300 sets the dpi that the PDF is rendered at.

-trim removes any edge pixels that are the same color as the corner pixels.

-quality 100 sets the JPEG compression quality to the highest quality.

Things like -sharpen don't work well with text because they undo things your font rendering system did to make it more legible.

If you actually want it blown up use resize here and possibly a larger dpi value of something like targetDPI * scalingFactor That will render the PDF at the resolution/size you intend.
