Question 1

How do I convert iPhone video to MP4?

Accepted Answer

Select your iPhone video (MOV or HEVC file), enable Format Conversion, and choose MP4 as the output. Click Process Video and download the result. MP4 with H.264 plays on virtually every device, including Windows and Android.

Question 2

What is HEVC and why does it fail on some devices?

Accepted Answer

HEVC (H.265) is the codec iPhone uses by default for video. It produces smaller files than the older H.264 standard but is not supported by all devices and software. Older Windows PCs, many Android phones, and some web platforms cannot play HEVC without additional codecs. Converting to MP4/H.264 resolves these compatibility issues.

Question 3

Which format works everywhere?

Accepted Answer

MP4 with H.264 encoding is the safest choice — it plays on Windows, macOS, iOS, Android, and in web browsers. If you need the smallest file and your audience is on modern devices, HEVC/H.265 is more efficient but less compatible.

Question 4

What video formats can I convert between?

Accepted Answer

You can convert between MP4, MOV, AVI, MKV, and FLV formats. MP4 is the most widely compatible format and is recommended for sharing. MOV is preferred for Apple devices and professional editing software.

Question 5

How long does format conversion take?

Accepted Answer

Conversion time depends on video length, resolution, and your device. Browser-based processing is 3–5× slower than native software. Short clips convert in seconds, while longer videos may take several minutes. Progress is shown during processing.
