Frequently asked questions
Can I convert MOV to MP4?
Yes, when your browser can decode the video and audio codecs inside the MOV file. Most common MOV files work in current Chrome, Safari, or Edge, but support depends on the codec and operating system.
Why is MP4 unavailable in my browser?
The tool only enables formats that the browser reports it can encode. If MP4 encoding is unavailable, choose WebM or try the latest version of Chrome, Safari, or Edge.
What is the difference between a file format and a codec?
MP4, MOV, and WebM are containers that hold video and audio streams. Codecs such as H.264, HEVC, VP8, VP9, and AAC describe how those streams are compressed. A browser must understand the source codecs before it can convert the file.
Will the converted video include audio?
Yes. The converter carries the source audio into the new file when the browser can decode it and the selected output format supports it.
Is the video sent to a conversion server?
No. The source and converted files remain on your device. The conversion uses browser video, canvas, audio, and recording features locally.
How long does conversion take?
When the source codecs already fit the output format, the video is repackaged without re-encoding and finishes in seconds. When re-encoding is needed, the time depends on the video length and your device speed, and is usually still faster than the video duration.
