Frequently Asked Questions
Why do transparent PNGs need a background for JPG?
The JPG format cannot store transparency. We flatten transparent pixels onto the background color you choose so the result looks clean.
Is PNG to JPG lossy?
Yes. JPG is a lossy format, so the output is smaller but compressed. Choose quality 90+ to minimize visible differences.
Will the file be much smaller?
Usually yes. Photos and complex images shrink dramatically as JPG. Simple graphics with flat colors may not shrink much.
