Frequently asked questions
Does converting JPG to PNG improve quality?
It cannot recover detail already lost by JPG compression, but it prevents any further loss and gives you an editable, lossless file.
Will the PNG be larger?
Usually yes — PNG is lossless, so photo PNGs are bigger than the source JPG.
Is it private?
Yes, the conversion is done locally in your browser.
