How KEY to WEBM Conversion Works

The KEY file format stores data in the KEY format. Converting to WEBM produces a video file that packages VP8/VP9 or AV1 video with Vorbis/Opus audio in a royalty-free container designed for web streaming. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. This makes WEBM the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
