Convert Mac screen recordings to MP4
macOS saves screen recordings as MOV files. Colleagues on Windows, support portals and some learning platforms handle MOV badly or reject it, while MP4 plays almost everywhere.
MOV to MP4 converts the recording in your browser, so a recording of your screen, which may show private information, is not uploaded.
Screen recordings can capture more than you intend: notifications, open tabs, email previews or saved passwords in a browser bar. Before recording, close unrelated apps and turn on Do Not Disturb. Because the conversion runs in your browser rather than on a server, the recording itself is not sent anywhere, but you should still review the finished MP4 before sharing it with anyone. For bug reports, mention what you clicked and what you expected to happen, and keep the recording focused on that single problem so support teams can understand it quickly.
Step by step
- Record your screen with Screenshot or QuickTime on your Mac.
- Open MOV to MP4 and add the recording.
- Convert and wait; longer recordings take more time because your computer does the work.
- Download the MP4 and share or upload it.
Tips
- Trim long recordings before converting to save time and space.
- Close other heavy apps while converting long videos.
- For a short silent demo, a GIF made with MP4 to GIF can be easier to embed.
Questions
- Is the recording uploaded?
- No. Conversion happens in your browser.
- Is the sound kept?
- Yes. Audio in the recording is carried into the MP4.
- Why is it slow?
- Video conversion is demanding and runs on your own device; long recordings take longer.
