2. Sonix

Key Features:

  • Free trial
  • Accurate
  • User-friendly interface
  • Voice-over

Comparison with UniConverter:

Uniconverter neither mandates account or credit card information, nor does it have such a demanding paid subscription. The most important thing is that you can use Uniconverter’s free version of the video converter, but it has limited functions and watermark restrictions.

Veed may limit audio transcription to 10 minutes, and lacks customer service support.
