Morphr uses the browser’s own video decoder to pull a frame from your MP4 video and save it as WebP. You get one still image with no motion or audio — useful for a thumbnail or a single clean shot from a clip.
MP4 video and WebP, explained
MP4 is the video container almost everything can play, from phones to TVs to upload forms. Its H.264 video is the safe default when you just need a file to work everywhere. WebP is a modern Google format that is usually 25–35% smaller than JPEG or PNG at the same quality, with support for transparency and animation. Every current browser displays it.
Good to know
- Your MP4 video files never leave your device — everything converts locally in the browser, so even confidential ones stay private.
- Convert as many MP4 video files as you like at once; a batch comes back as a single ZIP.
- Everything runs in your browser, so large videos take longer and need enough free memory.
- No sign-up, no watermark and no size limit beyond your device’s memory.
The private way to turn MP4 video into WebP
With Morphr, the whole conversion runs inside your browser tab using your browser's built-in decoder, so your file is never uploaded to a server, queued, or stored. That makes it a safe choice for personal photos, scanned documents and anything you'd rather not hand to a third party.
