How to do it, step by step
- Select the MOV file.
- Leave the Quality on Auto to preserve the original picture whenever possible.
- Click Convert video and follow the progress.
- Check it in the player and download the MP4.
When this is useful
Send an iPhone video to someone using another device
MP4 opens on Windows, Android and most platforms.
Upload to sites and forms that do not accept MOV
Many portals ask for MP4.
Edit in programs without MOV support
MP4 is accepted by most editors.
Tips for a good result
- On Auto, if the video is already H.264 and the audio AAC, the swap is almost instant.
- If the file is still big, use WebFaz Video Compressor afterwards.
What this tool does not do
- Videos recorded in HEVC (H.265) must be re-encoded to H.264 inside the MP4, which is slower.
- One video at a time, and the conversion depends on the device’s memory.
- The app does not change the video’s resolution or aspect ratio.
- The new file carries the “WebFaz.com” credit in the metadata (comment and artist).
Frequently asked questions
- Does converting MOV to MP4 lose quality?
- No, if the video is already in a codec MP4 accepts and the Quality is on Auto: the content is copied. If it needs re-encoding, there is some loss.
- Why did the conversion take long?
- The video is probably in HEVC and had to be re-encoded. Long and 4K videos take longer.
