Convert HEVC to MP4
A phone or a modern camera recorded in HEVC to save space, and an older laptop, editor or upload form will not decode it.

Where the streams already fit the target container this is a lossless remux, which is close to instant. Otherwise it re-encodes, which in a browser is slow — keep it under a few hundred MB and send long videos to the cloud engine.

What actually changes
HEVC and MP4 are not the same picture in two wrappers.
The HEVC stream is decoded and re-encoded as H.264 inside MP4. Compatibility goes up, and the file typically grows by 30 to 50 percent because H.264 needs more bits for the same quality.
Worth knowing first
The size increase is the whole trade. HEVC exists specifically to store the same picture in fewer bits, so converting to H.264 for compatibility always costs disk space, and doing it repeatedly costs quality on top.
Questions
HEVC to MP4, answered
Why does Windows charge for HEVC playback?
HEVC carries patent licensing obligations. Microsoft ships the codec as a paid extension, where H.264 licensing is already covered.
Can I keep HEVC and just change the container?
Yes, if the target device can decode HEVC. That is a fast stream copy rather than a transcode.

MPEG-4 Video is lossy, so the quality control decides the trade between size and fidelity.
