About this tool

Video Converter

Upload a video, choose MP4, WebM or MOV and press Convert. MP4 (H.264) plays on every phone, computer, TV and social network; WebM makes small files for websites; MOV is the QuickTime format used by iPhones, Macs and editing apps.

You can also make the video smaller by choosing 1080p, 720p or 480p, and remove the sound. When a video already uses a codec the new format supports, it's copied over directly, which is almost instant and keeps the full quality.

Everything happens on your device with your browser's own encoder, so the video is never uploaded and there's no watermark or size limit.

    Convert in any direction between the three.

  • Change resolution

Usually, yes. Convert it to MP4 here: H.264 MP4 plays on practically every device. If your browser can't open the video at all, it uses a codec the browser can't decode; try Chrome or Edge.

Recent versions of Chrome, Edge, Safari and Firefox on phones and computers. It uses your browser's built-in video encoder (WebCodecs), which is usually hardware-accelerated, so it's fast. Chrome and Edge support the most formats.

No. The video is processed entirely in your browser and never leaves your device, so private videos stay private.
