What is an FLV joiner

FLV is a container format that is usually used by Adobe Flash Player in a web browser. It can store video, audio, and text.

Clideo's FLV Merger allows joining different videos, images and adding audio. You'll also be able to download the final result in any format you need.

The tool works online, so it won't take up the memory of your device. In the free version, each file that you add can be up to 500 MB, if it turns out to be not enough for you, you can always subscribe to Clideo Pro.

The best video editor. I've already tried out a lot of video editors, but this is the best one. It has everything in there, unlike others that need a lot of other websites to do different things. Thank you so much.
