PNG is generous to a fault: it stores a photograph pixel by pixel and produces a file several times larger than that picture needs to be. Turning it into a JPG is what makes it small enough to attach, to push through an upload form with a two megabyte cap, or to place in a document without bloating it. The re-encode runs in this tab, so nothing about the image is disclosed to a server.
Frequently asked questions
- How much smaller does a photo become as a JPG?
- A photographic PNG commonly shrinks to a fifth or a tenth of its size. Flat graphics shrink less and can even look worse, because JPG smears the hard edges that PNG stores cleanly.
- My PNG is transparent, what fills the background?
- White. There is no alpha channel anywhere in the JPG specification, so every see-through pixel has to be given a colour, and white is the one that suits documents and print.
- Can I undo this later?
- Not meaningfully. Saving the JPG back out as a PNG restores the file format but not the detail the JPG discarded, so hold on to the PNG if it is your only master.
