MP4 → WebM

Convert MP4 video to the browser-focused WebM format. The conversion engine runs on your device, so your file does not need to be uploaded to Formatify.

WHAT CHANGES

MP4 input, WebM output

Formatify decodes the source and creates a fresh WebM file. Quality and file size can change because the formats store video data differently.

PRIVACY

Your file stays in the browser

The self-hosted conversion code runs locally. Closing the tab clears the working data kept by the page.
