Frequently asked questions
Can I make the MP4 smaller or lower the resolution?
Yes. Open "More options" to pick a resolution (4K down to 360p), a frame rate (60, 30, 25 or 24 fps) and a quality level. These settings re-encode the video.
Is my video uploaded?
No. Everything happens in your browser using your own device. Your video never leaves your computer or phone.
Will converting to MP4 lose quality?
If your video already uses H.264 or H.265 (most MOV and many MKV files), it is copied with no quality loss. Other formats are re-encoded at high quality.
Which video formats can I convert?
MP4, MOV, WebM and MKV inputs are supported. The exact codecs your browser can decode may vary.
Is there a file size limit?
No paywall. The practical limit is your device's memory.
Which browsers are supported?
Recent Chrome, Edge, Firefox and Safari (16.4+). The tool uses WebCodecs, your browser's built-in video encoder, and tells you before you start if something isn't supported.
