Convert PNG to JPG

PNG is the format screenshots and graphics come in; JPG is the one forms and portals ask for. This page converts between them on your own device, and fills any transparent area with white — because JPG has no way to store see-through, and the default when nobody decides is black.

How to convert PNG to JPG

  1. Tap Choose a PNG and pick one file, or up to thirty.
  2. Tap Convert to JPG.
  3. Check the result, especially any part that used to be transparent, then save it.

Transparency has to become something

A PNG can record that a pixel is partly or completely see-through. A JPG cannot — there is no room in the format for the idea. So a converter must paint the transparent parts some colour, and a converter that never thought about it paints them black, because an untouched canvas is transparent black. That is how a cut-out signature arrives at a government portal as a black box.

This page fills with white, which is right for the overwhelming majority of cases: logos, signatures, cut-out product shots and anything that will sit on a white page. If your image is meant to sit on a dark background, converting it to JPG is the wrong move — keep the PNG.

Which format you actually want

JPG for photographs, and for anything a form asks for by name. PNG for screenshots of text, for line drawings, for logos, and for anything that needs transparency. The difference is not quality in the abstract: JPG throws away detail your eye is bad at noticing, which is a great trade for a face and a poor one for a screenshot of small text, where it leaves visible fringing around every letter.

A photograph converted from PNG to JPG will usually get dramatically smaller. A screenshot converted the same way will sometimes get larger, and will look worse. Convert when a form insists, not on principle.

Questions

Can I choose a colour other than white?
Not on this page. White is right for nearly every conversion people need, and an extra control on the commonest path is a cost paid by everyone. If you need a specific colour behind a cut-out, place it on that background before converting.
Will the JPG be smaller than the PNG?
For a photograph, much smaller. For a screenshot or a flat graphic, possibly larger — PNG is very good at large areas of one colour and JPG is not.
Does converting lose quality?
Yes, a little, because JPG is lossy by design. At the default setting you will not see it on a photograph. On text or hard-edged graphics you might, which is the case where PNG was the better format to begin with.
