Those picks count once per PC, not per batch, and a batch of 500 costs none until you choose. A license ($129 once) removes the watermark from everything you convert.
No. Contenta Converter is a one-time purchase. You pay once and own it forever, including all future updates. No monthly or yearly fees.
