WebM is a format designed purely for the web by Google. It uses efficient VP8, VP9, or AV1 codecs. While great for browsers like Chrome, it often fails to play on iPhones, Mac QuickTime, or within video editing software.
Our conversion engine bridges this gap. We take the highly compressed WebM stream and transcode it to the industry-standard H.264 (AVC) format. This is a complex process because VP9 and H.264 handle color and compression differently.
We use a two-pass encoding methodology to retain the visual sharpness of the original WebM file while ensuring the output MP4 is strictly compliant with the ISO Base Media File Format spec. This guarantees your video works on everything from a 2010 iPod to the latest Smart TV.

WebM is an open, royalty-free media file format designed for the web. It is sponsored by Google and is highly efficient for streaming. However, its focus on the web ecosystem means it lacks the broad desktop and mobile support that MP4 enjoys.
MP4 (MPEG-4 Part 14) is the swiss-army knife of video containers. It is supported by the MPEG group and is the default format for recording on almost all cameras and phones.
The conversion from WebM to MP4 involves a full transcode because the underlying technologies are different.
