Why convert PDF to BMP?
PDF is a fixed-layout document format that looks the same on every device. It is the standard for forms, contracts, invoices and printing.
Each page is rendered exactly as a PDF viewer would show it.
BMP is still required by some older Windows programs, embedded devices and simple tools that cannot read compressed formats.
