WEBM → MP4 · ON YOUR DEVICE
Screen recordings and web videos as MP4 that plays everywhere. Nothing is uploaded.
Not when the video is already H.264 with AAC audio: VidFold copies it into the MP4 without re-encoding, so quality stays the same and it’s fast. Other codecs, such as HEVC, VP9, AV1 or Opus, are re-encoded to H.264 and AAC at high quality.
WebM uses VP8, VP9 or AV1 video with Opus audio. Browsers play it, but many phones, editors and messaging apps don’t.
It’s the MP4 combination that almost every phone, computer, TV, browser and editing app can play.
No. VidFold processes the file with your browser’s own video APIs, on your device. Nothing is sent to a server, and location and device details are removed from the export by default.
Install it from your browser: it opens in its own window, starts instantly and keeps working without an internet connection. No app store, no account, nothing extra to download.
