MakeMKV contains both freeware and shareware functionality. You may use this software to convert or rip DVDs for free. Yet when it comes to "rip Blu-ray", you need to purchase a MakeMKV activation key after a 30-day trial period. If you only rip Blu-rays with MakeMKV occasionally and think it costs too much to buy this software, you can reinstall this software after 30 days to obtain a new trial period, as MakeMKV is a beta version.
