There's always the risk<br>
of corrupting some data (even if it happens the 0.01% of the time), and the<br>
conversion is likely not lossless, so you'll lose some quality. Also, the<br>
original creation and modification dates for the files might be lost in the<br>
process.<br>
<br>
I would start using the HEIF format for new files, but I'd leave old ones<br>
alone, just in case.<br>
