By the far the most user friendly software to use.

As a housewife at home looking to start a YouTube channel for fun with absolutely zero editing experience, it was so easy for me to teach myself via their YouTube channel. It takes the tediousness out of editing and encourages creativity. As long as Kapwing is around, I will be using their software.

Kapwing is my secret weapon!

This is one of the most powerful, yet inexpensive and easy-to-use video editing software I've found. I blow my team away with how fast and efficiently I can edit and turnaround video projects.

Kapwing is king.

Love this site.

As an English Foreign Language Teacher, this site helps me to quickly subtitle interesting videos that I can use in class. The students love the videos, and the subtitles really help them to learn new vocabulary as well as better understand and follow the video.

Excellent subtitling features

[It] works perfectly for me. Have been using Kapwing for a year or so, and their automatic subtitle tool gets better and better every week, it's rare that I have to correct a word. Keep up the good work!

Natasha Ball

Best online video service ever. And a miracle for deaf people.

[Subtitler] is able to autogenerate subtitles for video in almost any language. I'm deaf (or almost deaf, to be correct) and thanks to Kapwing I'm now able understand and react on videos from my friends :)

This tool should be in every social media account managers' bookmark list.

I use this daily to help with video editing. Even if you're a pro video editor, there is no need to be spending hours trying to get the format correct. Kapwing does the hard work for you.
