Ratings and reviews

Holy hell, this is rad. Free tool, no damn ads, mostly intuitive. Tools like this are unironically what the internet was made for.

Fast, simple a importantly no ads. G Happy to pay a cup of coffee.

This is the only free app that I could find that allows conversion to AV1 or HEVC easily and without watching annoying ads. While on vacation with slow upload speeds, this app was a life saver to post to YouTube!
