WEBM is a web video format, developed for streaming videos without delay. Some of the undeniable advantages of this format are free-of-charge mode of distribution, higher video quality even on obsolete devices, and compatibility with main streaming platforms.

On the other hand, it can be incompatible with mobile devices, especially outdated models. Also, WEBM is not supported by some browsers, and quite often this format requires the installation of additional codecs and plugins.

Still, sometimes you have to resize a WEBM file to make it meet the specifications of the chosen platform, such as YouTube or others. The altered recording will be of limited use due to the reasons mentioned above, so it may be a good idea to convert WEBM to MOV or MP4.

This tool can perform both functions. Basically, the functionality of Clideo’s WEBM resizer is limited to resizing and converting videos, which makes the service extremely easy to use. Follow three basic steps.

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.
