Convert between any two formats.

Your iPhone saves photos in a format Windows, Chrome, and half the internet still refuse to open. Here's how to convert HEIC to JPG, and what quietly gets dropped along the way.

PNG to JPG is a file size decision that usually works. Then you open the converted logo and it has a hard white box around it. Here is what actually happens in the swap.
