Key takeaways
- 01MP4 plays in nearly every video player, browser, and editor — MOV does not always.
- 02The conversion runs locally with WebAssembly, so videos are not uploaded.
- 03Audio and video codecs are preserved when possible, which keeps export fast and lossless.
Why convert MOV to MP4?
MOV is Apple's QuickTime container — common on iPhones, Macs, and pro video tooling. MP4 is the same kind of container in spirit, but it is the safer pick when sharing with Windows users, uploading to social platforms, or embedding in websites.
Converting locally avoids long uploads of large video files and keeps personal recordings on your device.
How to convert MOV to MP4
Drop the MOV in, run the conversion, and save the resulting MP4.
- 01
Open the MOV to MP4 tool
Go to Handytool's MOV to MP4 tool and drop your video onto the page.
- 02
Start the conversion
The browser uses WebAssembly to remux or re-encode the video into an MP4 container locally.
- 03
Wait for processing
Most short MOV files convert in seconds. Long, high-resolution recordings take proportionally longer.
- 04
Download the MP4
Save the converted file. The original MOV is untouched.
MOV to MP4 FAQ
Is the video uploaded?
No. The conversion runs in WebAssembly inside your browser, so the video stays on your device.
Why is my MOV slow to convert?
If the codec needs to change (e.g. ProRes inside MOV), the browser has to re-encode every frame. Plain H.264 MOVs remux almost instantly.
Will quality drop?
When the file is remuxed, quality is identical. When re-encoding is required, the result is near-original at sensible bitrates.
Can I convert many MOV files at once?
Yes. Drop a batch and the tool will queue them and produce a ZIP of MP4s.
