Why convert JPG to PNG?
JPG and PNG save pictures in different ways. JPG throws away a little detail to keep files small, which is great for photos. PNG keeps every pixel exactly as it is and can have a transparent background, which suits logos, screenshots and graphics with text.
One thing to know: converting a JPG to PNG does not bring back detail that the JPG already lost, and the PNG file is usually bigger. People mostly convert because a program or website asks for PNG, or because they want to edit a picture many times without losing more quality.
Good to know
A 2 MB JPG often becomes a 6 to 10 MB PNG. That is normal. If file size matters most, keep the JPG.
Questions people ask
Does converting improve my photo?
No. It cannot add detail that the JPG already lost. The picture looks the same, just in a different file type.
Why is the PNG so much bigger?
PNG stores every pixel without throwing anything away, so photos take more space than they do as JPG.
Will the PNG have a transparent background?
No. JPG has no transparency, so the PNG keeps the same background your photo already has.
Are my photos uploaded?
No. They are converted in your browser and never leave your device.
