Why convert WebM to MP4?
WebM is common on the web but not supported by every editor or device. MP4 plays almost everywhere, making it the safe choice for sharing.
Is it safe?
Yes. This conversion runs entirely inside your browser, and your WebM file is never sent to a server. Metadata such as location is also removed automatically.
