Frequently asked questions
What happens to a transparent background?
It becomes white. JPG cannot store transparency, and a white fill keeps the picture looking clean.
Why is the JPG so much smaller?
JPG drops detail the eye hardly notices, while PNG keeps every pixel. Photos benefit the most.
Can I turn the JPG back into a PNG later?
Yes, there is a separate JPG to PNG page, but it cannot bring back detail the JPG has already dropped.
How do I convert a PNG screenshot to JPG?
Choose the screenshot above or paste it with Ctrl+V (⌘+V on a Mac). It is converted right away, and you download a JPG.
Is PNG or JPG better for uploading to a website?
JPG for photos, because it loads faster. PNG for logos, icons and images with transparency or crisp text.
Will the colours change after converting PNG to JPG?
No, the colours stay the same. Only transparent areas change: they turn white.
