Combine WebM Files

What is a WebM joiner

WebM is an open container format for multimedia files that was first presented by Google in 2010. It supports VP8 and VP9 video, Vorbis and Opus audio.

Clideo's WebM Merger is able to combine videos, pictures and audio of different formats. It also lets you adjust the final result and save it in any extension.

Our service is online, it works on any device and in any browser with no installations needed. Each file that you upload can be up to 500 MB for free.

How to combine WebM files

1. Upload WebM and other files

   To add files from your device, click on "Choose files". Note that you can add all the needed content at once.

   To upload a video or an image stored online, click on the arrow on the right side and select the option you like.

   

2. Join WebM files together

   Add more files if necessary by using the menu of the top right. Then rearrange them.

   

   Select an aspect ratio among the four available ones. Crop the frame or add borders. You're also able to add an audio file, cut it and set its volume.

   

   Once you're done, select an output format on the bottom left and click "Merge".

   

3. Download the result

   The compilation is ready to be saved to your personal device or cloud storage. If you want to make some changes, click "Back to edit" — don't worry, this button won't make you start over.
