Why Convert MOV to MP4?

MOV files created on iPhones, iPads, and Macs use Apple's QuickTime container which fails to play on Android phones, Windows PCs, and web video players without QuickTime installed.

Converting to MP4 with H.264 encoding creates universally compatible video that plays on every device and embeds cleanly in any website.

Frequently Asked Questions

Will converting MOV to MP4 reduce video quality?
At the default 'High' quality setting, quality loss is negligible. MP4 and MOV often use the same H.264 codec; the conversion primarily changes the container, not the codec.
Does the MP4 keep the original audio?
Yes. The audio track is preserved in the converted MP4 file.
Why does the converted MP4 sometimes look different?
Some MOV files use Apple ProRes or HEVC codec. Re-encoding to H.264 MP4 for broad compatibility introduces minor quality tradeoffs, especially at lower bitrate settings.
Can I convert MOV files larger than 500 MB?
The browser converter supports files up to 500 MB. TeraConvert Desktop has no file size limit and processes large video files natively.
Is this conversion really free, and is my file private?
Yes. The browser conversion runs entirely on your device using WebAssembly. Files are never uploaded to a server and are discarded from memory when you close the page. There is no file size tracking, no account link to your upload, and no cloud storage.
Do I need to create an account to convert files?
No. The browser converter works without signing in. An optional account is only needed if you want to save favorites, track conversion history, or upgrade to the desktop app with Polar license activation.
How fast is the conversion?
Most browser conversions complete in a few seconds. Large files (over 100 MB) or heavy formats (video, high-page PDFs) take longer depending on your device's CPU and available memory. The desktop app runs significantly faster using native engines.
