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 M4A to WEBM
Will the video be black?
If the M4A has no embedded album cover, then the video will be a just black background. If your M4A contains album art, the WEBM video will display it throughout the whole duration.
Can the WEBM be uploaded to YouTube without a "Processing abandoned" error?
Yes, your converted videos can be uploaded to YouTube successfully. Still, keep in mind that music copyright laws may have an impact on your uploads.
Can I convert M4A to WEBM in bulk?
Yes, MConverter supports batch converting of multiple M4As to WEBMs simultaneously. You can even drag and drop folders containing M4As to convert to WEBM. Pasting M4A files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert an M4A file to WEBM, if its size is 2 GB?
Yes, with MConverter Pro you can convert big M4As, up to 2 gigabytes each. The free version lets you convert files up to 100 MB. If you need to convert M4A files over 100 megabytes, try MConverter Pro. If your files aren’t over 1 GB, then you can use MConverter Plus instead, as it’s cheaper.
Is converting M4As to WEBM safe with MConverter?
Yes, we encrypt your connection using industry standards. Plus, your M4A files are only accessible by you. 4 hours after the conversion completes, they are automatically deleted from MConverter’s servers. You can also delete your M4As and other converted files immediately after finishing the conversion by clicking the bin icon.
