What changes when you convert PDF to JP2
PDF describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the JP2 afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after. One PDF file can hold several pages or frames, while JP2 holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
