Convert PNG to JPG Online
Convert PNG images to compact JPG with a white background.
A screenshot or export saved as PNG is often far heavier than it needs to be. Converting to JPG produces a much lighter file for email, marketplace listings and page speed, and the conversion runs on your device rather than on a server.

What changes when you convert
JPG has no transparency, so any transparent area in the PNG is filled with white during conversion. If your graphic was designed to sit on a coloured background, keep the PNG.
JPG is also lossy. Fine text, sharp UI edges and flat colour blocks can pick up faint halos, while photographs convert cleanly. Screenshots full of small text are the usual case where PNG is still the right answer.
When PNG to JPG is worth it
Photographs, product images and anything with gradients are the best candidates — the JPG looks the same at a fraction of the size. If the result is still too heavy for an upload limit, compress it afterwards rather than converting twice.
What to do next
- convert back to PNG — for transparency or lossless re-editing
- squeeze the JPG further — a quality slider with a live size comparison
- crop before converting — fewer pixels means a smaller file to begin with
