Format description
WebM is a relatively recent video file format for storing high-quality, highly compressed videos with very little quality loss. Because it is also royalty-free, it is frequently used on the web for HTML5 video playback. Its container is based on a Matroska (MKV) profile. It used the VP8 and VP9 technologies for video, and Vorbis and Opus for audio.
Common questions about converting to WEBM
Can I convert to WEBM in bulk?
Yes, MConverter supports batch converting to WEBM. You can even drag and drop folders to convert to WEBM. Pasting files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert a file to WEBM, if its size is 2 GB?
Yes, with MConverter Pro you can convert big files, up to 2 gigabytes each. The free version lets you convert files up to 100 MB. If you need to convert files over 100 megabytes to WEBM, try MConverter Pro. If your files aren’t over 1 GB, then you can use MConverter Plus instead, as it’s cheaper.
Is converting to WEBM safe with MConverter?
Yes, we encrypt your connection using industry standards. Plus, your files are only accessible by you. 4 hours after the conversion completes, they are automatically deleted from MConverter’s servers.
