JPG does not support transparency. If your PNG has a transparent or partially transparent background, those areas will automatically be filled with white in the converted JPG. If you need to keep transparency, keep the file as PNG, or convert to WebP instead, which supports an alpha channel.
PNG is the right format for screenshots, logos, and graphics — but it produces noticeably larger files than JPG for the same image, especially for photographs. If you are attaching an image to an email with a size limit, uploading to a form that only accepts JPG, or preparing a photo for print, converting to JPG is usually the fix.
The size reduction can be substantial. A PNG screenshot or photo that's several megabytes often shrinks to a fraction of that size as a JPG, with no visible quality loss at quality settings of 85 or above. The trade-off is that JPG uses lossy compression, so some image data is discarded — for most everyday uses like email, web forms, and printing, this is not noticeable.
The one case where converting is the wrong move: if your PNG has a transparent background you actually need — a logo that has to sit on different coloured backgrounds, for example — converting to JPG will permanently flatten that transparency to white. Keep a PNG copy of anything you might need transparency for again later.
For website photos specifically, JPG is a reasonable choice, but WebP typically produces an even smaller file at the same visual quality while still supporting transparency if you need it.
