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.

How to combine FLV files into one

Add FLV files
Click the "Choose files" button and select the necessary videos from your device. If you want to add a video stored on Google Drive, Google Photos, or Dropbox, call a drop-down menu by clicking on the small arrow. Note that you can add not only FLV but files of any format.
Merge FLV and other files
Rearrange the FLV files to your liking. Set one of the available aspect ratios and crop the frame. Upload a soundtrack, click on the scissors icon to cut it, and adjust its volume. When you're all done, choose a format and click on "Export".
Save joined FLV
Take a look at the result. If you like it, download it back to your device or cloud storage. Otherwise, you can go back to editing without the need to start over.

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.
